Torq LE User Guide Decks

DJing begins with music, so you will get to know Torqs Decks very well. A Deck is what Torq LE uses to play back a single digital music le and is analogous to the turntable or CD player used by DJs. The Deck allows you to play a track, change its speed and its key, as well as rearrange it by looping and jumping to new locations within the song. Torq is equipped with two of these Decksone on each side of the screen.

Main Waveform Display

One of the wonderful benets of computer technology is the ability to visualize audio. While being interesting to the eyes in their own right, waveform displays can be an invaluable tool when DJing. Torqs user interface is dominated by two such waveforms at the top-center of the screen, one corresponding to each of the Decks. Use these scrolling waveforms to check the synchronization of tracks, locate sounds, predict breakdowns, and much more.
Its all in the mix, or so they say, and Torqs Mixer delivers the goods. The Mixer takes the audio from the two Decks and gives you control over what can be heard by means of volume controls, audio equalizers, and a crossfader. Two Decks and a Mixer: the essential tools for a DJ.
Torq LE User Guide PFL/Headphone Cue
DJs commonly listen to a track on their headphones without letting their audience hear it. This allows them to match the tempo of the new song to the current one, along with nding the correct starting position for the song. Torq LE will allow you to monitor either Deck on headphones, and also features a stereo headphone split normally reserved for high-quality DJ mixers.

Browser/Database

There is a third ingredient to DJing, and thats musiclots of music. To help you stay on top of your massive music collection, Torq LE features a Database for cataloging and searching tracks. It will monitor your favorite folders and allow you to create playlists for future performances.

Effect Racks

Effects are a great way for you to manipulate (or mangle) your music in unique ways to enhance your mix. Torq LE has three built-in effects that are specically designed for DJ use: dual lter, phaser, and strobe. You can use these three effects on each Deck.

Master Module

When all is tweaked and mixed to perfection, the resultant audio is sent to the Master Output. Torq LE features an automatic output limiter that will keep your music from distorting as well as a module for recording the nal mix to a le as you play. You can then burn the results onto a CD or convert them to MP3 for podcasts.

< Loop In/Out Looping an entire song doesnt have much benet for a DJ, so Torq allows you to move the Loop Markers by using the Loop In and Loop Out buttons: 1. Load a song into a Deck and press Play. The song will begin to play. 2. When playback reaches the beginning of the section you want to loop, click the Loop In button. This will place a Loop In Marker at the Now Line (shown as an yellow marker line in the scrolling and overview waveforms) and the song will continue to play. The Loop In marker will snap to the beginning of the nearest 16th-note in the song waveform. 3. When playback reaches the end of the section you want to loop, click the Loop Out button. This will place a Loop Out Marker at the Now Line, which will also snap to the nearest 16th-note. At the same time, the Loop On/Off button will automatically be activated causing playback to jump back to the Loop In Marker. The music will now loop between these two points indenitely. 4. When youre nished looping this section of the song, you can click the Loop On/Off button to turn it off. Now, when playback reaches the Loop Out Marker, it will simply pass it and proceed playing the rest of the song. Note: If you reposition playback using one of the QuickCue buttons while Looping is activated, playback will jump to the new location. Torq will then automatically place the Loop In Marker at that point and will place the Loop Out Marker in a position to maintain the same loop length in use prior to pressing the QuickCue button. < Loop On/Off The Loop button will indicate whether Torq is looping audio or not. Whenever this button is illuminated, Torq will be looping something, whether triggered with one of the QuickLoop buttons or set manually with the Loop In and Loop Out buttons. Click this button to toggle looping on and off. < QuickLoop More often than not, a DJ will loop audio that is an even number of beats or bars. That is, they will loop a single bar (four beats) or two bars (eight beats), or may do micro-loops of only one or two beats. Instead of having to quickly press the Loop In and Loop Out buttons to create loops of these lengths, Torq LE provides one-button access to these loops via the QuickLoop buttons. Using QuickLoops The QuickLoop buttons allow you to instantly loop a section of a song by a preset length. By default, each of the four buttons represents a different bar length; one bar, two bars, four bars, and eight bars. Simply press one of these buttons at the beginning of the section you want to loop and Torq will automatically place the Loop In and Loop Out Markers in the appropriate locations: 1. Load a song into a Deck and press play. 2. Press the QuickLoop button labeled 1. The Loop button will be switched on and the Loop In Marker will immediately be placed at the Now Line. Furthermore, the Loop Out Marker will be placed exactly one bar later and the song will begin looping a perfect bar. 3. To turn the loop OFF, click the Loop button. Playback will now proceed beyond the Loop Out Marker.

QuickLoop Size Preference As mentioned above, the default loop lengths for the four QuickLoop buttons are one bar, two bars, four bars, and eight bars. The QuickLoop Size preference allows you to change the QuickLoop buttons to beat values instead of bar values: 1. Open the Torq LE Preferences menu and click on the Behaviors tab. 2. Click the arrow next to QuickLoop Size option and choose Beat from the drop-down list. 3. Click the X to close the Preferences window. Now, when you use the QuickLoop buttons as described above, youll nd that they capture loops of one beat, two beats, four beats, and eight beats in size. QuickLoop Behaviors Along with the obvious functions stated above, the QuickLoop buttons are capable of a few other behaviors: You can change various loop lengths while the song is looping. For instance, if you have set a one-beat loop, pressing the 4 button will automatically extend the Loop Out marker to make the song loop perfectly four beats. Also, repeatedly pressing a QuickLoop button will cut the current loop length in half. For example, if you press QuickLoop 2 to loop two bars of audio, pressing the button again will change the loop to one bar in length. Pressing it again will reduce the loop length again, this time to two beats (half a bar). By holding the Shift key while pressing these buttons, the opposite behavior will occur: The loop will double its length each time you press the QuickLoop button. Speed Slider Torqs Decks are each equipped with a Speed Adjust slider for the purpose of beat-matching songs. This slider behaves just like the pitch adjusters found on DJ turntables and CD players. As you move this slider, the neighboring ADJ display will show how much the songs speed is being altered (expressed as a percent where 0% is the original speed of the song). For those not familiar with these controls, your rst impression may be that the slider is working backward since the speed of the song will increase as you move the slider down on screen. However, this is the proper behavior for pitch controls found on DJ turntables and CD players. It makes sense if you consider the following: The pitch adjust slider on a turntable is mounted at on the surface of the turntables housing. Therefore, when you use the slider, you either push it away from you or pull it towards you. When a song is going too fast, you push the slider away from yourself, just as if you put out your hand in a slow down motion. If you need the song to go faster, you pull the slider toward you, similar to how you would gesture towards yourself if you wanted someone to move quickly. After a few hours of practice, this backward response will feel natural.

< Slider Range By default, the range of the Speed Adjuster is +/- 8%. That means that if you move the slider to either of its extremes, youll only get an 8% change in the speed of the song. To the left of the Speed Adjuster is a display showing the current range setting for the slider: You can change the range of the Speed Adjuster by clicking on this range display. Each time you click, the range will advance to the next highest setting. The order is: 8%, 10%, 20%, then 50%. When you click the display again, the range will wrap around back to 8%. Youll only need to increase the range when youre trying to match two songs with very different tempos, or when you want to perform an extreme speed change as a special effect. Most experienced DJs will simply match the tempos of two songs by hand using the Speed Adjust slider, which is a perfectly acceptable method of matching songs (indeed, this is the way its been done for decades). Since it requires a lot of practice to hear when one song is playing faster or slower than another, those new to DJing will benet from some of the extra features built into Torq LE. Such features include automatic beat detection, BPM displays, scrolling waveform displays, and automatic synchronization. < BPM Display Tempo is a measurement of the speed of a song and is normally expressed as Beats Per Minute (BPM). As the BPM increases, the speed of the song increases. In order for two songs to be mixed together with their beats aligned, the two songs will need to be playing at the same tempo. This is why Torqs Decks are equipped with Speed Sliders. In the event the DJ is trying to mix two songs with different tempos (which happens more often than not), he will need to use the Speed Sliders to match the tempo of the new song to the tempo of the current song. Automatic BPM Detection Any time you load a new track into a Deck, Torq will analyze it and attempt to determine the tempo of the song. For most dance music, Torq LE will be able to determine the tempo accurately. Once scanned, the tempo of the song will be shown in the BPM display for the Deck, which is located just to the left of the Speed Adjust slider. The BPM shown here is a living valueit will change when you alter the speed of the song with the Speed Adjuster. This is extremely helpful when trying to synchronize two songs since youll be able to nearly match the tempos of the two songs just by matching the BPM values shown in the displays. Double/Halve Button When Torq LE incorrectly identies the tempo of a song, it will often return a result that is half the original tempo or double the original tempo. This occurs frequently when using Drum & Bass tracks with tempos in the neighborhood of 170 BPM. Torq may think that the tempo of the song is 85 BPM, which is half the actual tempo. When this happens, you can quickly double the tempo using the Double/Halve button. The rst time you press this button, the up arrow will light and the tempo of the current song will be doubled. The second time you press the button, the down arrow will light and the tempo of the song will be cut in half from the original tempo. The third time you press this button, the arrows will turn off and the tempo will revert to the originally detected tempo.

Phase Grid Torq LE superimposes a Phase Grid over the Scrolling Waveforms to indicate the location of the beats in a song. The thicker lines in the Phase Grid indicate the locations of the downbeats in the music. Torq will attempt to position the Phase Grid in the proper location as part of the analysis when loading a song into a Deck. Torq uses the position of the Phase Grid to properly synchronize the song.

Playback Manipulations

The Waveform Display allows you to manipulate the song playback in a variety of ways using your mouse. The method of control differs depending on the control type you have selected for the Deck (Vinyl/CDJ/Hybrid). Vinyl Mode With this mode selected, using the mouse on the waveform will work in a similar fashion to using your hand on a turntable. 1. 2. 3. Click and hold the mouse on the waveform. Playback will stop, as if you have placed your hand on a record to stop it. Continue holding the mouse button, then drag the mouse left and right. This will scrub, or scratch, the song. Releasing the mouse button will cause the Deck to play the song back from the current location.
Hybrid Mode With Hybrid mode active, the waveform will respond exactly like the CDJ mode while the Deck controls (Play/Pause, Cue, etc.) behave like Vinyl Mode. 1. 2. 3. 4. Click and hold on the waveform. The music will continue to play While holding on the mouse button, drag the mouse left. The playback tempo will be momentarily increased, making the waveform scroll a little faster to the left. Now hold and drag the mouse to the right. Playback will remain going forward, but the tempo will be slowed slightly, resulting in a waveform that still scrolls right to left, but at a slower rate. As soon as you stop dragging, playback will return to its original tempo even if you are still holding the mouse button.
CDJ Mode With this mode selected, the waveform will not be scratched with the mouse. Instead, mouse movements will simply nudge the music ahead or behind by a small amount. 1. 2. 3. 4. Click and hold on the waveform. The music will continue to play While holding on the mouse button, drag the mouse left. The playback tempo will be momentarily increased, making the waveform scroll a little faster to the left. Now hold and drag the mouse to the right. Playback will remain going forward, but the tempo will be slowed slightly, resulting in a waveform that still scrolls right to left, but at a slower rate. As soon as you stop dragging, playback will return to its original tempo even if you are still holding the mouse button.

SYNCHRONIZATION

t most of todays dance clubs and events, the DJ will mix the songs together using a technique called beat-matching. The goal is to fade the volumes between two songs while keeping them perfectly in beat with one another. If done properly, the audience will never have to stop dancing as the beat of one song will blend in with the beat of the new songsounding like one single song. DJs will do this for hours at a time, creating one gigantic non-stop mix from the individual songs they have in their collection. Proper execution of this technique requires the mastery of two tasks: matching tempo and matching phase.

Torq LE User Guide File List
The window to the right of the Browser pane is called the File List. If you have selected a source in the Browser that contains music (such as the Database or an individual folder), the songs contained therein will be listed here. The File List not only shows you the name of the song, but also shows the artist name, album name, track number, genre, and other elds contained within the songs ID3 tag. These additional categories can help you nd song with greater efciency. Note: While ID3 tags will support storage of the information listed above, it is common to nd music les with some (if not all) of the ID3 elds blank. Even if the music le does not contain information for all categories, you are still able to ll in the missing info by hand in order to aid in searching through your les. Editing Fields Torq LE will extract the relevant song information from the les ID3 tag in order to populate the elds of the File List as described above. You are free to edit the information shown in the File List simply by double-clicking a eld and typing in new data. It is important to note that Torq LE does not update the songs ID3 tag with your edits. Instead, your edited elds are stored in a special le with the same name as the song, but with the extension.tqd at the end. This is the Torq LE Data le. By saving your edits to the TQD le, Torq LE can save your changes much faster (changing an ID3 tag requires re-writing the entire audio le, something that could affect system performance during live use). Additionally, the audio le could become corrupted during the re-write process. So, Torq LE leaves your precious music les untouched by saving data to the TQD le. Artist/Song Filename Swap Occasionally the ID3 tag information of a song (described above) may contain incomplete song information. In the worst case, the ID3 tag may not even contain the name of the song or the artist who wrote it. When this happens, Torq LE will list blank audio les (they will look blank in the File List, but youll still be able to load them and play them). Obviously, its almost impossible to tell which les youre working with in this situation, so Torq LE will allow you to swap out the Song and Artist categories with one larger Filename category: 1. 2. Right-click (CTRL-click on Mac) on the Artist or Song category heading. The Artist or Song category will then be replaced with a single Filename category that will display the lename of the song rather than the artist and song information contained in the ID3 tag.

< Reset Button When you are done with your search and are ready to begin a new one, press the Reset button. This will clear the Search and Ignore elds as well as deselect any categories that had been previously selected. Playlists While many DJs will perform off-the-cuff without any previous rehearsal or forethought, other DJs will pre-program their sets, either due to the complexity of the set or simply as a method for remembering vital songs (this can be helpful for wedding or party DJs who take requests). Torq features Playlists to help you organize and store lists of songs. You can create and manage multiple Playlists, each with as many songs as you like. Each Playlist can then be edited by adding or deleting tracks, or by rearranging their order within the Playlist.
< Creating New Playlists To start, you must create a new Playlist as follows:
1. Right-click (CTRL-click on Mac) on the Playlists heading in the Browser and choose New Playlist from the pop-up menu. 2. A new Playlist titled Empty Playlist will appear below the Playlist heading (click the plus sign in front of Playlists in order to see this list). Note: If there is already an Empty Playlist in the list, a number will be appended to the name to differentiate it from the other(s), i.e. Empty Playlist 1. < Rename Playlist 1. Right-click (CTRL-click on Mac) on your desired Playlist and choose Rename Playlist from the pop-up menu. 2. Type in the new name you would like to give the Playlist and hit the Enter key on your computer keyboard. 3. The Playlist will display its new name. < Deleting a Playlist 1. Right-click (CTRL-click on Mac) on the Playlist and choose Delete Playlist from the pop-up menu. 2. The Playlist will be removed from the list in Torq LE. It will still be on your computer, however, stored in the Deleted Playlists folder. These Playlists will be kept for up to 30 days, then permanently deleted. < Duplicating a Playlist If you like a particular Playlist and would like to build a new one based upon it, you can duplicate (or copy) it for future modication. 1. Right-click (CTRL-click on Mac) the Playlist you would like to duplicate and choose Duplicate Playlist from the pop-up menu. 2. A duplicate of the selected playlist will be created and displayed underneath it. 3. A number will be added to the name of the Playlist to differentiate it from the original. Of course, you can rename this Playlist using the method described above. < Adding Songs to a Playlist Once you have created and selected a Playlist, youll begin adding les to it using the following procedure: 1. Using the Browser or Database, locate the song youd like to add to the Playlist. 2. Right-click (CTRL-click on Mac) the song name and select Add to Playlist from the pop-up menu. 3. The song will be added to the bottom of the Playlist. < Removing Songs from a Playlist You can remove songs from a Playlist as follows: 1. Right-click (CTRL-click on Mac) the song in the Playlist you wish to delete. 2. Select Remove from Playlist from the pop-up menu. 3. Torq LE will remove the song from the Playlist, but the song will remain in the Torq LE Database (it will not be deleted from your computer).

Channel Volume Faders Besides going to the PFL, the audio leaving the EQ also goes to the Channel Volume fader. This is the primary volume control for the channel (though it is subordinate to the crossfader) which works just like a volume fader on a traditional mixer. You can match volumes of the two tracks using the Channel Volume faders. However, some DJs prefer the technique of leaving the Channel Volume faders fully upyou then match the volumes of the songs using the Gain knobs. The reason for this is that youre then free to use the Channel Volume faders for other effects such as volume fades, cuts, and stutter effects, similar to the scratch techniques used on the Crossfader. Whichever approach you choose is entirely up to you. Note: You can quickly return a Channel Volume fader to full volume by holding SHIFT and clicking on the fader. Crossfader After the audio leaves the individual mixer channels via the Channel Volume faders, the signals enter their respective sides of the Crossfader. The Crossfader is the large horizontal fader just below the Mixer. As you will see, its name is very appropriate as it allows you to fade between the two channels in a motion that goes side to side across the mixer. When the Crossfader is in its middle location, you will hear both of the mixer channels. If you move the Crossfader all the way to the left, you will only hear the channel for the left Deck. Similarly, if you move the Crossfader all the way to the right, you will only hear the right Deck. The Crossfader was invented to offer DJs an easy way to fade out of one song while fading in another while only using one hand. Indeed, it still performs this task quite well. However, since its introduction, DJs have taken this simple tool and transformed it into a virtual razor blade that allows them to perform lightning-fast cuts, scratches, and a myriad of other techniques. Note: Torqs Crossfader has been designed to be very quick and responsive. However, if you are only using a mouse to control Torq LE, you probably wont be able to use the Crossfader for more than fading between songs. If you want to use the Crossfader for cuts and scratching, we recommend you control the Crossfader using one of the real Crossfaders found on M-Audio or SynchroScience MIDI controllers (such as X-Session Pro). The tactile response of the Crossfader comprises part of the scratching technique. < Crossfader Curve Speaking of scratching, one of the improvements to crossfader design is an adjustable Crossfader Curve. This refers to the rate at which the songs fade in and out as the crossfader is moved from one side to the other. At one extreme is the Equal Power Contour, which is good for slow fades between two songs. As you move the fader from the edge toward the center, it will slowly fade in one song. However, as it is fading in this song, it will also start fading out the other song. The end result is that the overall volume remains the same as you fade, even when both songs are playing at the same time. At the other extreme of the adjustable range is the Hard Cut. This shape causes a song to fade in to full volume almost immediately after moving the fader inward from the edge. Similarly, the other song will not begin to fade out until the crossfader is almost all the way at the other edge. Then, right before the crossfader reaches the edge, the other song will fade down. This is the shape preferred by scratch DJs as they can cut in a track to full volume with very little motion of their hand. When performed quickly, you dont even hear the volume fade up and downit sounds as if the sound is being abruptly cut in and out.

< Tweak Knob This knob will adjust the Cutoff Frequencies of the lters. When the Tweak button is off, the knob will behave as follows: 1. Placing the knob at 12 oclock will result in the audio passing through the Dual-Filter unaffected. 2. Turning the knob counterclockwise from 12 oclock will begin to lower the Cutoff Frequency of the Low-Pass lter. You will hear the music become dull and mufed as you turn this down to the point where youll only hear low bass rumbles. 3. Turning the knob clockwise from the 12 oclock position will begin to raise the Cutoff Frequency of the High-Pass lter. You will hear the music become more thin and brittle as you do this until only the highest of the high frequencies remain. When the Tweak button is on, the Tweak knob will merely control the center frequency of the BandPass lter. As you turn the knob down (counterclockwise), youll hear the high frequencies become mufed while you begin to hear more of the bass. Strobe Just about anyone who has been to a dance club in the last 20 years has experienced a strobe light. Those are the super-bright lights that ash really quickly. They have the effect of making everyone look like theyre in stop motion the ash is so fast that you cant see movement anymore. Torqs Strobe effect will create a similar stop-motion effect, but it will do it to audio. The Strobe will essentially mute and unmute the audio at a rate that you can control. The rate can be as slow as one bar (2 beats unmuted followed by 2 beats muted) or as fast as 1/64-note. < Enable Button Turns the Strobe effect on and off. < Tweak Knob This knob changes the rate of the Strobe. A tooltip will appear whenever you adjust this knob to show the current rate (expressed in note values).
< Tweak Button Activating this button reverses the behavior of the Strobewhat was normally muted will be unmuted and vice versa.

Torq LE User Guide Chapter 12 Torq LE User Guide Chapter 1
Sample Rate Below the Audio Interface selection you will see sample rate adjustment. Increasing this value will improve sound quality (depending on your source material) but will also place heavier demands on your computer. It is therefore recommended to leave the sample rate only as high as you need it to be. If you only play MP3 les or songs from CDs, you wont really have any reason to raise this value beyond 44,100 since that is the sampling rate used by MP3s and CDs.
Buffer Size The other important setting for your audio interface is the Buffer Size. This parameter can cause a lot of confusion for some users, but is actually not that complicated. To understand how the buffer size affects the performance of Torq, you must understand a little bit about how your computer processes audio. Multi-tasking is a term that refers to doing multiple jobs all at once. Its what allows your computer to run more than one program at a time (i.e. listening to iTunes while surng the Web). While it looks like the computer is doing two separate things at once, its actually notits still doing only one task at a time, but changing between tasks faster than you can see. This provides for a streamlined computing experience, but creates a problem when using audio applications. Audio is non-stopa 5-minute song will play for 5 minutes without interruption. So how can the computer keep audio playing while its jumping around to do other tasks? The answer is buffering. An audio buffer is a temporary storage tank that can hold a brief moment of audio. The computer will ll the audio buffer with music then let the buffer play while it does other things (like update the clock on your screen, check your network connections, monitor RAM usage, etc.). When all things work properly, the computer will complete its other tasks and ll the buffer with more data before the buffer empties, thus resulting in perfect audio while multi-tasking. If the audio buffer happens to empty before the computer can ll it with more data, the audio playback will stop until the computer can ll the buffer again. These dropouts happen very quickly, not sounding like prolonged gaps of silence, but sounding more like clicks and pops or otherwise distorted audio. When this happens, the solution is to either lighten the CPU load (by closing unnecessary applications or processes that are wasting the computers time) or by increasing the size of the audio buffer, allowing it to play longer (thus giving the computer enough time to perform its other tasks). So why not just go with a large buffer size and avoid dropouts? The problem is that increasing the buffer size increases the system latency. Latency is the time between when you tell the computer to do something (such as activating an EQ Kill) and when you actually hear the results from the speakers. If you have a large audio buffer, the buffer will have to play out its entire contents before youll hear any new EQ changes in the audio. When DJing, this can be a nightmare if youre trying to do things with accurate timingall of your actions will have a delayed effect on the music. The solution is to set the buffer size as low as it can go without inducing any audio problems. This is just like playing a game of limbo: 1. 2. 3. 4. 5. 6. Load some music into a Deck and play it. While the music is playing, open the Audio Preferences. If music is playing back properly, open the Buffer Size menu and select the next smallest buffer size. The buffer will be updated immediately and the music will continue to play. Listen to the music for a moment. If it sounds clean (no click, pops, or glitches), then lower the Buffer Size to the next lowest setting. Keep repeating this procedure, listening to the quality of the audio each time, until you reach a setting where the audio breaks up. Once you nd this lower threshold, set the Buffer Size to the next highest setting (the last one that worked properly) and your system will be optimized. While Torq should be very stable at these settings, keep in mind that the system performance can be compromised as you increase the CPU load.

Torq LE User Guide Chapter 12 Torq LE User Guide Chapter 1 Miscellaneous Tab
This tab contains miscellaneous options that affect the behavior of certain features of Torq LE.
Torq Engine This setting is used to switch the Torq Audio Engine between Normal and Economy modes. This option should be left on Normal unless you have a slow computer. Switching to Economy will degrade graphical performance and have a slight impact on sound quality, but can often allow Torq LE to run smoothly on older machines. Cue Exclusivity This option affects how the Deck Cue buttons behave. When this option is On, pressing the PFL button on a channel will cause the PFL button on the other channel to turn off. This will ensure that you are only hearing one audio source through your headphones at a given time. When this option is Off, you can cue multiple channels at once. These Cue sources are mixed and heard through your headphones simultaneously. With each channel that is added to the Cue mix, the overall Cue bus volume wi
Schaffel Mode Schaffel is German for shufe, which has become a popular form of dance music based on a triplet rhythm as opposed to a straight 4/4 rhythm. When this mode is activated, any of the effects (or parameters that quantize their values) will include triplets in their quantizing options. Take the Strobe effect for example: The Parameter knob changes the rate of the Strobe effect. Normally, this would select rates of 12, 14, 1/8, 1/16, and 1/32. With Schaffel engaged, the knob would quantize to 12, 14, 1/8, 1/8T, 1/16T, and 1/32T. The T after the number stands for Triplet. Note: Selecting a triplet quantization will give the effect or parameter a shufed or funky feel. QuickLoop Size This option affects how the QuickLoop buttons behave. When this preference is set to Bar, your loops will be established in lengths of musical bars. When this preference is set to Beat, your loops will be established in lengths of musical beats. Search iPod with Database When this preference is set to Yes, any connected iPods will have their music libraries incorporated into the Database for instant searching. If this option is off, you will have to specically select the iPod Library in the Browser to view its contents. Search iTunes Library with Database If you happen to have a copy of Apple iTunes installed on your computer, selecting Yes for this option will integrate its Music Library into Torqs Database. Any songs currently a part of your iTunes Library will be instantly accessible in Torq along with all other folders assigned to the Database. If this option is off, youll have to specically select the iTunes Library in the Browser window to view its contents.
Transport Mode The Nudge and Offset buttons in the Decks can have their directions reversed using this preference. By default, this option is set to Reverse, meaning the buttons operate in a manner similar to a DJ using turntables. Instead of pressing right to go faster or ahead in the song, youll press left (just like the closest edge of a record spinning past a DJ). If you prefer more of a tape machine style control, switch this option to Normal. Tooltips If you hover your mouse over a control in Torq LE, often a small Tooltip will appear describing the function of the control. Additionally, when you move a knob or slider with the mouse, a Tooltip will be displayed showing the new setting of the knob or slider. This preference chooses the level of detail in the Tooltips. Fullwhen selected, all Tooltips will be displayed, both when you hover your mouse and when you operate a control. Adjustwhen selected, the only Tooltips that will appear are those showing the adjustment applied to a knob or slider. The normal Tooltips seen when hovering the mouse over a control will be hidden. Nonewhen selected will disable all Tooltips entirely.

Sync Mode This option determines the forcefulness of the synchronization used in Torq LE. Barwhen selected, Torq will align a synced Deck to the tempo and downbeat of the other Deck. Any attempts to adjust the alignment of the track will result in Torq forcing the tracks back into synchronization with their downbeats aligned (the thick lines of the Phase Grids will be aligned with each other at all times). Beatwhen selected, Torq will match a synced Deck to the tempo and beat of the other Deck with no regard to the downbeats in the Phase Grids. Any attempts to realign the synced Deck will result in Torq forcing the track back into alignment with the nearest beat (the thick lines of the Phase Grids may be out of alignment with each other). Tempo Onlywhen selected, Torq will only match the tempo of a synced Deck to the other Deck. When you press Play on the Deck, Torq will not force the song into alignment. It will be up to you, the DJ, to start the music at the right moment and keep it in alignment.
Skin This option allows you to select a different Skin or color scheme for Torq LE. 1. 2. 3. Click to drop down the Skin menu. Select a skin (color-scheme) from the list. Torq will change its color scheme, but all interface features will maintain their shape and orientation within the interface.

English

Welcome

Tutorial

Part I: Preparation
First, well need to check a few settings required for the following examples Click the icon in the upper right section of the Torq LE window. The Audio Preferences dialog opens. Make sure your soundcard is selected under Audio Interface. (Windows users: If a driver with the word ASIO in its name is available, select it) 3. Click on the eld labeled Master Output and check the available choices: For serious DJing, you need a soundcard that features separate stereo outputs for pre-listening (cueing) and for the sound the audience hears. Your soundcard features only one stereo output. Torq still allows you to use all of its features, including pre-listening, by using a trick: Torq splits your soundcards stereo output into two mono outputs one for prelistening and one for the audience (the left/right choices in this dialog). All you need to follow the examples in this tutorial is a Y-adapter cable that connects to your soundcards stereo output via a male 1/8 jack and provides two female 1/8 jacks for your headphones and your sound system. You can nd such cables at every well stocked electronicsor music store. Please also check the full Torq User Guide for more information, which can be found on the in the Torq LE application folder.
a. If Left / Right / Left -- Right are available: Select Left for Master Output and Right for the Cue Output.
b. If there are multiple entries listed in the Master Output eld, and some of them say 1/2 in their name and others say 3/4: Select a 1/2 driver for the Master Output and a 3/4 driver for Cue Output. Make sure to connect your sound system to your soundcards rst stereo output and your headphones to your soundcards second stereo output.
Torq MixLab is composed of two parts: the Torq LE DJ software and the M-Audio X-Session Pro DJ controller. Torq LE is a full-featured DJ application that has all the functions youd nd on expensive DJ CD players and turntables. It plays back music at varying speeds and pitches and automatically matches tempos of songs, creating smooth transitions between tracks. You can also perform remix tricks such as looping and instant jumps to other locations in the song. Lastly, Torq LE allows you to apply effects to the music and fully control the mix of the songs. The M-Audio X-Session Pro provides you with hands-on control over Torq LE. After plugging the X-Session Pro into one of your computers USB ports, Torq LE instantly recognizes it. Moving the controls on the X-Session Pro results in the corresponding on-screen controls moving in kind. This is the best way to DJ since you can perform multiple tasks at once on the controller, as opposed to controlling only one thing at a time with the mouse. DJing is an art. As with any art, it takes practice to become procient. However, there are many features in the Torq MixLab package that will jump-start your learning process. This manual describes the features and use of the Torq MixLab system and offers insight into the art of DJing. Once you are procient with Torq MixLab, the skys the limityoull be ready to take the step up to the tools used by the pros!

Food For Thought

In some ways, DJing resembles the circus tricks of spinning plates or juggling objects. As the DJ, it is your job to keep everything up in the air in a smooth fashion, so that the music never stops as you move from one song to another. All of the tools available to you merely inuence and cajole the playback of music that would normally play straight through, uninterrupted and independent from each other from beginning to end. It is therefore a necessity to think one step ahead of where you are, since some DJ techniques must be performed before you actually want your audience to hear them. This ability to anticipate changes in the music directly relates to how well you know the music in your library. If you know the structure and patterns of a song like the back of your hand, youll know what sections are appropriate for looping, interesting places to introduce lters and other effects, and empty or quiet areas where you might need to mix in another song. Intimate knowledge of your music library is also what helps you select the right progression of songs, by choosing songs of similar style and feel.

Part II: Overview

Getting the Music Together
1. If youre using a PC, click the + in front of My Music in the Browser pane. If youre using a Mac, click the + in front of Music in the Browser pane. 2. Right-click on the Torq Traqs folder (CTRL+click if using a Mac with one mouse button) and select Add to Database. 3. Torq LE now includes the Torq Traqs folder in any searches of the Database. You can conrm this by clicking on Database in the Browser panethe following list of songs should be displayed:
In case this is your rst stab at mixing, weve provided you with an exciting and diverse collection of music from various M-Audio M-Powered artists. During installation, the installer copies this collection onto your hard drive, in a folder called Torq Traqs. If you are a Windows user, youll nd this folder in your My Music folder. Mac users will nd the folder in their Music folder. In order to help you select songs, Torq LE includes a Browser and Database to organize your music library. To search and sort your music library with ease, simply add your music folders to the Database. To illustrate, lets start by adding the Torq Traqs folder to Torq LEs database:

Playing Music

1. Click on the song titled Somnambulist by BT and drag it up to Deck A on the left side of the screen. Release the mouse button to load the song into the Deck. Move the crossfader on your X-Session Pro to the left. This ensures that youll hear only Deck A. Press the Play/Pause button to start the song. You should now hear the music from you computers speakers. You can adjust the overall volume of Torq LE using the Master Volume slider, located to the right of the crossfader (pictured below). Keep an eye on the meter in this windowif the top segments light up, turn down the Master Volume until they turn off. This prevents the music from distorting.

The next step is to load one of the songs onto a Deck, so you can play it:

Loading the Next Song

1. Click on the song titled Gabriel and Dresden Club Mix, and drag it up to Deck B (on the right side of the screen). Release the mouse button to load the song onto the Deck.
While the BT track plays on Deck A, you can load another song into Deck B:

Part III: Action!

Previewing the Next Song
1. Put your headphones on and press the Right Headphone Button on the X-Session Pro. Youll see the PFL/Headphone icon light up on the right side of the Mixer on screen.
Turn down the headphone volume by moving the Headphone Volume slider to the left with the mouse.
Press the Play/Pause button on the right side of the X-Session Pro to start playback of Deck B. Youll hear the beginning of Gabriel & Dresden Club Mix in your headphones. Turn up the Headphone Volume slider until the song is at a comfortable listening level.
Now take off your headphones. Notice that you still hear the BT track over the speakers and not Gabriel & Dresden? That is because you moved the Crossfader all the way to the left. Pressing the headphone button on the right mixer channel allows you to hear Gabriel & Dresden (Deck B) privately in your headphones.

Synchronizing the Songs

Put your headphones back on, but leave one of the earcups off. This way, you can hear one song in your speakers, and the other in your headphones. Notice how the two songs are completely out of sync with each other? It sounds pretty terrible. If you were to try to mix Gabriel & Dresden into the speakers right now, it would result in what DJs fondly call a train wreck. In order to avoid a train wreck, you need to change both the speed and position of Gabriel & Dresden so that it matches the speed and position of BT. Torq LE has a handy Sync button to accomplish this task for you. Click the Sync button on Deck B and listen to what happens.
The two songs now play at the same speed and are in sync with each other. You can see that the BPM values for the two Decks are matched, indicating that the songs are running at the same speed.

Mixing the Songs

1. Slowly move the crossfader on the X-Session Pro from the left towards the center. Youll hear the Gabriel and Dresden track fade in on top of BT. 2. When the crossfader is at the middle, youll hear both songs at the same time. Both songs are playing in sync so they almost sound like one. Continue moving the X-Session Pro crossfader towards the right. The BT track on Deck A will start to fade away. When the crossfader is fully right, youll hear only the Gabriel and Dresden track on Deck B.
Now that you have Deck B synchronized to Deck A, you can try mixing them together:
Congratulations! You just performed your rst DJ crossfade! It may not have sounded as smooth as other DJ mixes youve heard, but this was only your rst attemptand you may not have heard those songs before. Once you begin to work with familiar music, youll nd it easier to do clean crossfades.

Part IV: An Advanced Mix

So lets take this up a notch. In this example, youll mix three songs together. Youll start with Defective by The Crystal Method, mix into Picture Of You by East Coast Boogiemen & DJ Heather, and nally, youll mix into A Spirit Lost by The Nova Dream Sequence. You wont use the crossfader to mix this timeyoull leave it right in the center. Instead, youll use the EQs and Filters to create the mix. Youll see how adjusting the frequencies of a song can help create a subtle blend between songs. This example also introduces you to QuickCue Markers. There are ve assignable QuickCue markers for every song. When placed in the song, they appear in the small Overview Waveform in the Deck and in the larger Scrolling Waveform display in the middle of the screen. They show up as white numbers with a white circle around them, and Torq LE saves their locations with every song. We have already placed the QuickCue Markers in the songs youre about to use. During this example, youll perform certain tasks when playback reaches these various markers. Lets get started: 1. Click on the song Defective by The Crystal Method and drag it over Deck A. 2. Replace Somnambulist with Defective by releasing the mouse button. 3. Move the Volume A slider on the X-Session Pro down 4 lines. This turns down the volume of Defective, which happens to be a very loud song. 4. Press the left Play/Pause button on the X-Session Pro to start Deck A.
< The next song youre about to load onto Deck B is not as loud as Defective on Deck A. Youll therefore need to increase the volume of Deck B in order to match the loudness of Deck A: 1. Use the mouse to increase the right Gain knob all the way to +6dB. This makes the song twice as loud as normal, in order to match it with the song on Deck A. 2. On the X-Session Pro, turn the right Low EQ knob down all the way. This action removes the bass frequencies from Deck B when it starts playing.
3. Click on Picture Of You (Kens Drunk on Jack Mix) by ECB & DJ Heather and drag it up to Deck B. Release the mouse button to load the track. 4. Click the Sync button on Deck B to turn it on. Even though the ECB & DJ Heather song is already the same speed as The Crystal Method (they both have a BPM of 125), having Sync on keeps the two tracks aligned with each other automatically.

1. By looking in the Overview Waveform in Deck A, youll see that the yellow Now Line is slowly approaching QuickCue Marker 1. Put your nger on the Play/Pause button for Deck B so youll be ready to press it.
2. When playback gets close enough, youll also see QuickCue Marker 1 show up in the Scrolling Waveform display, as shown below.
3. When QuickCue Marker 1 is in the center of the Scrolling Waveform, press Play/ Pause on Deck B. This action starts playback of Deck B and synchronizes it to Deck A. It should look like this:
If all went smoothly, you now hear both The Crystal Method and ECB & DJ Heather playing from your speakers at the same time.
< Your next task is to start the ECB & DJ Heather track at just the right moment so that it will play along with The Crystal Method in a complimentary fashion. Weve placed a QuickCue Marker in Defective to indicate where Picture Of You should start.
< Next, youll use the Filter effect to remove the high frequencies from Picture Of You, right when the drums stop in Defective. Weve placed a QuickCue Marker in Picture Of You to indicate where this should happen. 1. If you look at the Overview Waveform for Deck B, youll see that the yellow Now Line is approaching QuickCue 1. Put your hand on the Filter knob for Deck B (this is the knob in the upper-right corner on the X-Session Pro controller). 2. When QuickCue Marker 1 of Deck B (pictured in the Scrolling Waveform display) passes under the Now Line, quickly turn the Filter knob counter-clockwise to the 9 oclock position (the indicator will be pointing to the left). This makes the ECB & DJ Heather song sound mufed, and youll only hear a little bit of the bass drum. 3. Now slowly turn up the Filter knob as the music builds in this section. Your goal is to have the knob at 12 oclock when QuickCue Marker 2 passes under the Now Line of Deck B. If you did that properly, then you managed to cause the ECB & DJ Heather track to mirror the same pause in energy as heard in The Crystal Method songyou made the two songs sound like one. < This whole time, the bass has been removed from Picture Of You because you turned the Low EQ knob on Deck B all the way down. In a moment, the bass on Defective will stop, and youll need to turn the Low EQ back up: 1. You should see the yellow Now Line of Deck Bs Overview Waveform approaching QuickCue 3. Go ahead and put your hand on the Low EQ knob of Deck B. 2. When QuickCue 3 scrolls under the Now Line at the center of the Scrolling Waveform display, quickly turn the Low EQ knob to the 12 oclock position. 3. With the bass restored, the ECB & DJ Heather track carries the beat during this breakdown in The Crystal Method track. 4. When QuickCue 4 passes under the Now Line, quickly turn the Low EQ back downfully counter-clockwise. This removes the bass from Picture Of You when the beat in Defective starts again. By turning down the bass in one of the songs, it allows your mix to sound cleaner. While not always necessary, this is a good trick to remember, as playing multiple bass parts together often sounds bad.

1. When QuickCue 2 of Deck A passes under the Now Line, slowly turn down the Filter on Deck A. 2. Youll want to do this slower than before, as your goal is to have the Filter knob at the 9 oclock position, right when Defective ends. 3. At the same time, put your hand on the Low EQ knob for Deck B. Turn this knob to the 12 oclock position the instant Defective ends. That action allows the bass from Picture Of You to take over when Defective ends. < Now that Defective has ended, its time to load a new song in its place. Youll use A Spirit Lost by The Nova Dream Sequence: 1. Now that Defective has ended, turn off the Sync button on Deck B. This will keep Picture Of You playing at its current speed when you load the next song. 2. Click and drag A Spirit Lost from the File List and drop it onto Deck A, replacing Defective. 3. This song is not as loud as Defective, so turn the left Volume slider on the X-Session Pro all the way up. 4. Turn the left Filter to the 12 oclock position, in order to disable the effect. 5. Turn the Low and Mid EQ knobs on Deck A all the way down. Youll also need to turn up the High EQ to roughly the 3 oclock position (so the indicator on the knob is pointing to the right). 6. Press the Sync button on Deck A to match tempos to Deck B. A Spirit Lost is now standing by to play. 7. When QuickCue Marker 5 of Picture Of You passes under the Now Line, start A Spirit Lost by pressing the Play/Pause button. The songs should sync up as shown below:
< Very soon, youll reach the end of the song Defective. To help make the transition as smooth as possible, youll use the Filter to gradually mufe the song until it ends.
< Unlike a moment ago, when you started Picture Of You, you wont hear A Spirit Lost when you rst start playing it. This is because you removed the majority of the frequencies in the song by turning down the Low and Mid EQ knobs. Therefore, to make the song audible, youll need to turn up the EQ knobs. 1. When Deck A reaches QuickCue Marker 1, quickly turn up the left Mid EQ knob to the 9 oclock position. 2. Continue to slowly turn up the Mid EQ. Your goal is to have the knob set to the 11 oclock position when A Spirit Lost reaches QuickCue Marker 2. Youll hear the synthesizer pattern from A Spirit Lost begin to fade in as you do this. 3. Once youve passed QuickCue Marker 2, play around with the Phaser effect on Deck A. Slowly move the knob around and listen to the sound of the synthesizer pattern change. 4. When playback of Deck A reaches QuickCue Marker 3, youll need to do two things at once. First, turn the Phaser knob all the way down (to turn off the effect). Second, turn the Low EQ of Deck A to 12 oclock. 5. Immediately turn the Deck A Mid EQ the rest of the way to the 12 oclock position. At the same time, use your other hand to turn down the Mid EQ on Deck B by the same amount. This action causes A Spirit Lost to become the dominant song in the mix. 6. Continue to turn down the Mid EQ on Deck B until its completely counter-clockwise. You should do this before A Spirit Lost reaches QuickCue 4. 7. When A Spirit Lost reaches QuickCue Marker 4, the bass drum in the song stops, but youll still hear the bass drum from Picture Of You. Slowly turn down the Low EQ on Deck B during this breakdown, to make the bass drum fade away. The Low EQ should be all the way down by the time A Spirit Lost reaches QuickCue Marker 5.

Give yourself a pat on the backyouve just performed a rather complex mix between three songs! In case you didnt perform everything just right, feel free to repeat this example until it feels natural. Also feel free to experiment with other mixing techniquestry using the High EQ knobs in addition to the others when blending between tracks. Try using the crossfader, too, to add volume changes to the mix. In the end, its all about what you like to hear. Experiment! These two examples offer only a glimpse of what is possible with Torq MixLab. Please continue reading the complete Torq MixLab user guide on the included CD-ROM to learn the specic details of the Torq LE program, or refer to the interactive manual (press the Help button of Torq LE, located at the top right of the application, and choose User Manual from the resultant dialog box). There are many features that you havent used yet. There are also some troubleshooting tips for synchronizing tracks in the event that Torq LE doesnt analyze the song properly (some music cant be analyzed due to variations and complexity in the song). Read more and youll be ready to mix anything at your next party or podcast.
