CHAPTER 1 GETTING STARTED

1.1 INTRODUCTION

What It Is
The Alesis QuadraVerb GT is a stereo effects unit that is ideal for guitar. It combines analog and digital electronics to provide the best of both worlds. Analog effects include: Compression Distortion Flat/Presence/Brightness Control Bass Boost Speaker Cabinet Simulator (ideal for use with headphones or recording direct; can be bypassed when feeding a guitar amp) Noise Gate Programmable Effects Loop for inserting other effects (can also provide a signal send from the analog outputs, and receive a return signal into the digital processor) The digital effects are the same ones that have made the QuadraVerb Plus a favorite in studios and live equipment racks world-wide: Reverb Delay (stereo or mono) Pitch Change (chorus, flange, detune, phaser, etc.) Equalization (graphic or parametric) Panning and Tremolo Ring Modulation Tunable Resonators (a very resonant filtering effect) Sampling (up to 1.5 seconds of sound can be captured and replayed) The order of the analog effects are preset in their optimum positions; the routing of the digital effects is flexible and programmable. All effects parameters are editable. 100 edited programs can be saved in memory, and called up by front panel switches or MIDI program change commands. The QuadraVerb GT is also MIDI controllable. Settings need not be staticyou can control them in real time with Continuous Controller foot pedals, or with sequencers or keyboards.

1.4 FOOTSWITCH HOOKUP

There are two footswitch jacks on the rear panel that accept standard, normally open, momentary contact footswitches. A footswitch plugged into the Bypass jack duplicates the BYPASS button function. Press on the footswitch to toggle between bypass and active modes. When bypassed, the LED in the middle of the BYPASS button will be lit. A footswitch plugged into the Advance jack increments (or decrements)
the program number by one with each footswitch press. You can set an upper and lower program number limit, as described in section 5.7.
1.5 EXTERNAL EFFECTS HOOKUP
The QuadraVerb GT offers an effects loop where you can patch in effects other than the ones included in the unit (you might want to insert, for example, a wah-wah pedal or vintage fuzz). The effect can be bypassed or enabled for each patch. Patch the Effects Loop Send jack to the effect input, and the Effects Loop Receive jack to the effect output. Also note that the Send jack provides a post-analog effects, pre-digital effects send suitable for driving guitar amps or a studio console; the Receive jack lets you plug directly into the digital effects and bypass the analog effects. The effects loop can therefore split the QuadraVerb GT into two separate effects, as described in section 2.1. It is important to note that turning off the effects loop does not turn off the effects send. Selecting In or Out on the Effects Loop page will only enable or disable the Effects Loop Return jack. Also, the effects loop will be bypassed if there are no jacks inserted, regardless of whether the Effects Loop page is set to On or Off.

1.6 SETTING LEVELS

After hooking up your cables, set the proper levels. Start off with your amplifier turned down to a low volume to prevent any ear-shattering surprises as you learn about the QuadraVerb GT. After you know what you're doing, increase the level to normal monitoring levels. 1. Press the BYPASS button (its red LED will light) so that you hear only the straight guitar sound. 2. Play your instrument and observe the 4-step LED meter toward the left of the QuadraVerb GT. 3. Adjust the Input control so that the -6 dB LED lights consistently but the Clip (red) LED lights rarely, if ever. The red LED indicates that distortion is either about to occur or is actually occurring. 4. Adjust the output control for a comfortable monitoring level. Make sure the output is turned up high enough to provide the amplifier, mixer, or subsequent processor with sufficient level, but not turned up so high that it overloads the unit it is feeding. 5. Press the BYPASS button again so that you can hear the effect of the different QuadraVerb GT programs. BYPASS can be used at any time to toggle between processed and straight sounds.

The multiple effects are all placed in parallel. Each effects output feeds a
mixer, and is variable so that you can change the balance of that particular effect with respect to the overall sound. The effect input can come from the main input if you only want the effect to process the dry sound, but in many configurations, the effect can get its input from the output of other effects, or from a combination of processed and dry sounds.

Modulation

As mentioned earlier, many QuadraVerb GT parameters can be changed in real time via pedals that generate continuous controller commands, or from commands issued by a sequencer or synthesizer. Continuous controller pedals are available from a variety of manufacturers at various price points. These generate signals that are tagged with a particular controller identification number. If you set a QuadraVerb GT parameter to be controlled by this particular controller number, moving the pedal will change the QuadraVerb GT parameter. Modulation consists of choosing up to 8 target parameters to be modulated by any one of several types of MIDI source data types (pitch bend, aftertouch, note number, and note velocity as well as continuous controllers). Several parameters can be changed by one controller, so that, for example, moving a pedal could increase chorus depth and boost the midrange frequencies.

Bi-Timbral Effects

The QuadraVerb GT can serve as two separate effects units by proper patching to and from the effects loop. For example, consider a situation where a guitarist plays guitar and sings. Plug the guitar into the QuadraVerb input; the effects loop send provides the post-analog effects signal, which can be routed to a guitar amp. Meanwhile, the voice mic can be externally preamplified and sent into the effects loop return. This allows the vocal to be processed by the digital chorus, reverb, equalization, etc. sections. The QuadraVerb GT output, which now carries only the processed vocal sound, can be routed to a PA for further amplification.

2.2 ABOUT CONFIGURATIONS

No matter which program you select, the analog effects are always in the same order. However, the digital effects can be connected together in one of eight different ways, each of which is called a configuration. A configuration doesn't just include a specific collection of effects, but also the way in which they interconnect (e.g., whether the delay signal is derived from an equalized or non-equalized signal). This allows for a great deal more flexibility than you would expect from a fixed configuration of effects. This flexibility allows for some great sounds, but also requires a bit of experimentation to learn the subtleties of each configuration and how these subtleties affect the sound. It's probably easiest to start off by tweaking the factory presets to learn what the different parameters do, then graduate to creating programs from scratch. These configuration descriptions use block diagrams to indicate signal flow. Keep the following in mind: Think of the connecting lines as patch cords between different effects boxes (the individual modules). Switches are enclosed in rectangular boxes with rounded corners. The knobs act as volume controls if two wires hook into the knob, or mix (pan) between two signals (incoming wires) and provides an output (outgoing wire) if three wires hook into the knob. Heavy lines indicate a stereo path. Note that most effects output a stereo signal, but accept a summed, mono signal at the input.

4.7 A WORD ABOUT EQ, RESONATORS, AND GUITAR TONE

Resonators, EQ, and Tone

A guitar tone is a complex thing. Factors as diverse as the wood, size, and shape of a guitar can alter its tone. Strings, pickups, hardware, active electronics, and a myriad of other factors make up the distinctive and elusive intangible known as "tone". All of these factors, however, have one thing in common: they alter the harmonic structure of the guitar's sound. While the fundamental frequency of A above middle C is 440 Hz, the timbre of the note itself is made up of not only the fundamental frequency, but a series of overtones (harmonics) as well. When you play an A on one guitar, the note will have a unique sound. When you play an A on a different guitar, the note will have the same 440 Hz fundamental, but can have a completely different sound. This is due to the difference in overtones. This difference, which can be caused by all of the previously mentioned factors, means that every guitar setup has its own unique sound. Its own unique tone. The Quadraverb GT's EQ/Resonator section gives you specific control over fundamental and harmonic overtones in your guitar's tone. The parametric EQ gives you precise control of the fundamentals of your guitar tone by increasing or decreasing the amplitude of specific pitches over a variable bandwidth. By tuning the resonators and controlling their amplitude and delay resonance you can accentuate harmonics in your guitar tone. A resonator is a special filter whose response is so sharp that it actually imparts a pitch to any signal going through it.

Programmable Tone Curves

To simplify the process of getting a great guitar sound (after all, you'd rather play, right?), each configuration in the Quadraverb GT includes six preset tone curves with EQ and/or resonator parameters that have been pre-programmed to yield certain types of guitar tones with a minimum of programming. You can easily select one of these tones and store it to the program you're working on, or, if you wish, you can use the presets as starting points for creating your own custom tone curves. You might want to create tone curves for specific programs to be used with specific guitars, for example.
4.8 EDITING 3-BAND EQ AND RESONATOR PARAMETERS (config 1)

EQ Preset

The display says: EQ PRESET: U SER This page allows you to access 6 preset tone curves, or to create your own curve from scratch. The EQ and/or resonator parameters of the 6 preset curves have been programmed to give you a variety of tones to choose from. To listen to each tone curve, press the Up VALUE button which will scroll through presets 1 through 6. If you find a preset you like, you can store it to the current program by pressing the STORE button twice. To use a preset as a starting point for your own custom tone curve, simply edit its EQ and/or resonator parameters until you have the sound you want (for more about the specific parameters, see their explanations below). Then press the STORE button twice. This will store the edited tone curve as part of the program that you are currently working on. The next time you call up that program, your edits will appear as the program's USER curve. Configuration 1 has 6 tone curves. They are: #1 (3 Band EQ Mode) #2 (3 Band EQ Mode)

4.11 EDITING 5-BAND EQ AND RESONATOR PARAMETERS (config 4)
The display says: EQ PRESET: U SER This page allows you to access 6 preset tone curves, or to create your own curve from scratch. The EQ and/or resonator parameters of the 6 preset curves have been programmed to give you a variety of tones to choose from. To listen to each tone curve, press the Up VALUE button which will scroll through presets 1 through 6. If you find a preset you like, you can store it to the current program by pressing the STORE button twice. To use a preset as a starting point for your own custom tone curve, simply edit its EQ and/or resonator parameters until you have the sound you want (for more about the specific parameters, see their explanations below). Then press the STORE button twice. This will store the edited tone curve as part of the program that you are currently working on. The next time you call up that program, your edits will appear as the program's USER curve. Configuration 4 has 6 tone curves. They are: #1 (5 Band EQ Mode) #2 (5 Band EQ Mode) #3 (5 Band EQ Mode) #4 (5 Resonator/3 Band EQ Mode) #5 (5 Resonator/3 Band EQ Mode) #6 (5 Resonator/3 Band EQ Mode)
The display says: EQ MODE: 5 RESONATOR/3 EQ This page switches between the 5 BAND EQ and 5 RESONATOR/3 EQ modes.

Low EQ Frequency

Low EQ Amplitude
Low Mid EQ Frequency (5 Band EQ mode only)
The display says: LOW MID EQ FREQ 500Hz
All three midrange filters are parametric types. This parameter sets the lower midrange frequency at which signals will be boosted or cut.
Low Mid EQ Bandwidth (5 Band EQ mode only)
The display says: LO MID EQ WIDTH 1.00 OCTAVES Bandwidth refers to the width (range of frequencies) of the band of frequencies that will be affected by the EQs boost and cut values. Example: A bandwidth of one octave boosts a wider range of frequencies than a bandwidth of 0.2 octaves.
Low Mid EQ Amplitude (5 Band EQ mode only)
The display says: LOW MID EQ AMP + 00.00dB This sets the amount of boost (positive numbers) or cut (negative numbers) at the lower midrange frequency set on the Low Mid EQ Frequency page.
The display says: MID EQ FREQUENCY 2000Hz All three midrange filters are parametric types. This parameter sets the midrange frequency at which signals will be boosted or cut.
Hi Mid EQ Frequency (5 Band EQ mode only)
The display says: HIGH MID EQ FREQ 05000Hz All three midrange filters are parametric types. This parameter sets the high midrange frequency at which signals will be boosted or cut.

The display says: HIGH EQ FREQUENCY: 08000Hz This sets the frequency above which all signals will be boosted or cut by the amplitude amount set on the next page.
The display says: HIGH EQ AMPLITUDE: + 00.00dB This sets the amount of boost (positive numbers) or cut (negative numbers) at the High EQ Frequency set on the previous page.
4.13 EDITING 5 BAND RESONATOR (config 7 only)
Resonator Gate Mode (config 7 only)
The display says: RESONATOR GATE MODE: M IDI GATED There are two options, Continuous and MIDI Gated. In Continuous mode, the resonators are active at all times, with the tuning set by the tuning parameter on subsequent pages. In MIDI Gated mode, the resonators track up to five notes you play on a MIDI keyboard. Example: Play C2, E2, G2, D3, and G3 on a MIDI
keyboard, and the five resonators will assume those pitches; the resonators will change to different notes as you play different keys. Furthermore, the MIDI notes gate the resonators on and off. So, when a resonator receives a MIDI note-off message, it will decay to zero according to the decay time (set on the next page) even if theres still a signal present at the QuadraVerb GT input.
Resonator Decay (config 7 only)
The display says: RESONATOR DECAY: 90 This sets a global decay time for all five resonators. The higher the number, the longer the decay.
Resonator Tune (config 7 only)
The display says: RESONATOR 1 TUNE + 00 SEMI TONE The PAGE buttons switch between the 5 resonators, as shown by the upper line. The VALUE buttons tune the resonators in semitones over a five-octave range, from -24 semitones to +36 semitones. If MIDI gated mode is selected, standard chromatic pitch tracking will occur only if the tuning for all resonators is set to 00. However, if you offset the resonator tunings and play the same MIDI key repeatedly, youll hear an arpeggiator effect.
4.14 EDITING MIX PARAMETERS (config 1)
Configuration 1 offers separate mix levels for the Preamp or EQ, Pitch,
Delay, and Reverb modules, tremolo or panning, and master/direct mix levels.

Direct Signal Level

The display says: DIRECT LEVEL: 50 This sets the level for the direct signal path. Use this and the Master Effects level control to balance the levels of the straight and processed signal paths.

5.1 SELECTING THE SAMPLING CONFIGURATION
Configuration 8 is used for sampling. All sampling parameters are accessed through the DELAY module (although the EQ button is used for triggering and stopping sample playback). To select this configuration: 1. Press the CONFIG button. 2. Press the UP VALUE button until the display reads: CONFIGURATION: SAMPLING

5.2 RECORDING A SAMPLE

There are two ways to record a sample. In the first (the easiest way to get a good sample), the QuadraVerb GT waits for the incoming audio to trigger recording. With the second method, pressing the front panel BYPASS button initiates recording.
Recording By Audio Trigger
1. Press the DELAY button. The display says: SAMPLE PLAYBACK: LOOPING (The lower line may also show ONE SHOT or AUDIO TRIGGER.) This page is primarily for playback and can be bypassed for now. 2. Press the PAGE UP button three times. The display says: AUDIO TRIGGER SAMPLING: ON 3. Use the VALUE buttons to select Audio Trigger On mode (if it is turned off). 4. Press the BYPASS button. The display says: WAITING FOR AUDIO THRESHOLD 5. Send a signal to the QuadraVerb GT. When the first LED (-18dB) lights, the input signal has passed the audio threshold and recording has begun. For the best signal quality, vary the input level control so that the -6dB LED lights. The signal, and sample, will be distorted if the red "Clip" LED lights.
Recording from the Front Panel
1. Press the DELAY button. The display will read: SAMPLE PLAYBACK: LOOPING (The lower line may also show ONE SHOT or AUDIO TRIGGER.)
This page is primarily for playback and can be bypassed for now. 2. Press the PAGE UP button until the display says: AUDIO TRIGGER SAMPLING: ON 3. Use the VALUE buttons to select the Audio Trigger Off mode. 4. Press the BYPASS button to start sampling. The display will read: SAMPLING.
For the best signal quality, vary the input level control so that the 6dB LED lights. The signal will be distorted if the red "Clip" LED lights.

Playing Back a Sample

There are three ways to play back a recorded sample: from the front panel, from an audio trigger, or through MIDI. Playback from the front panel (manual playback) would normally be used when you want to manually trigger a recorded sample. Playback from an audio trigger is useful for replacing one audio source with a recorded sample, as in the case of replacing a snare drum on a tape track with a better recorded sample. Playback through MIDI enables a recorded sample to be played, and transposed, from a MIDI keyboard. NOTE: Make sure that the Sample Playback Level in the Mix section (section 7.2) is set to an audible level (i.e., greater than zero).

Front Panel Playback

1. Press the DELAY button. The lower display line shows either ONE SHOT or LOOPING: SAMPLE PLAYBACK: ONE SHOT ONE SHOT means that once a sample is initiated, it will play until the end of the sample and then stop. If you want to play back the sample continuously until you tell it to stop, select LOOPING. 2. To begin playback, press the EQ button. The sample will play to the end and then automatically stop. To play back again, press EQ again. If you selected LOOPING in step 1, push the EQ button to stop sample playback. 3. Use the OUTPUT control to increase or decrease the sample volume.

Audio Trigger Playback

1. Press the DELAY button. The display says: SAMPLE PLAYBACK: ONE SHOT 2. Press the VALUE UP button until the display reads: SAMPLE PLAYBACK: A UDIO TRIGGER Any incoming audio signal that passes the threshold (makes the 18dB LED light) will cause the sample to play.
The recorded sample can still be manually played back by pressing the EQ button.
Looping is not available in the Audio Trigger mode. Once a sample is audio triggered, the -18dB LED must turn off before sample can be re-triggered.

MIDI Playback

It is also possible to trigger the recorded sample from a MIDI keyboard in two different ways: MIDI One Shot When the QuadraVerb GT receives a MIDI note on, the recorded sample will play back to the selected sample end point, regardless of how long that the key is pressed. MIDI Gated The sample will stop playing when you lift your finger off the key. It is also possible to select the note on the keyboard that will trigger the sample at its original pitch, as well as the highest and lowest notes to which the sample will respond.

Select MIDI Trigger Mode

1. Press the DELAY button. The lower display line shows either ONE SHOT or LOOPING: SAMPLE PLAYBACK: ONE SHOT 2. Press the PAGE UP button until the display reads: MIDI TRIGGER: GATED Use the VALUE buttons to select the desired mode: MIDI Gated The sample stops playing as soon as the key is released.
Off The QuadraVerb GT will not respond to MIDI note on/off information). MIDI One Shot The recorded sample will play back to the selected end of the sample, regardless of how long the key is pressed. IMPORTANT: If the playback mode is set to "Looping" and MIDI Trigger is set to One Shot, the sample will play indefinitely until the mode is changed or the sampling configuration is deselected. MIDI Trigger and Sample Playback mode need to be set to the same value (either both Looping or both One Shot.)
Select the MIDI Trigger Note
1. Assuming the DELAY module is selected, use the PAGE buttons to select the display that says: MIDI TRIGGER LOW LIMIT: 000 2. Press the VALUE UP button to select the lowest note that can trigger the recorded sample. (Note number 60 = Middle C.) 3. Press the PAGE UP button. The next display says: MIDI TRIGGER BASE: 060 4. The Base value is the note where the sample plays back with no pitch change. Press the VALUE buttons to select the desired note. 5. Press the PAGE UP button. The next display says: MIDI TRIGGER HIGH LIMIT: 060 6. Press the VALUE DOWN button to select the highest note that can trigger the recorded sample.

Because of the nature of sampling, the timing of the sample as well as the pitch will change the farther away from the base note from which it is transposed, with the higher notes sounding like munchkins and the lower notes like giants. This is a normal phenomena that occurs during sample playback. The pitch of the sample will follow within a 2 octave range and will loop back into the range if any note information falls outside of the 2 octave range. For instance, if the base note has been selected to note number 60 (Middle C or C3) and you play note number 84 (C5), the sample pitch will be triggered 1 octave higher than the bass (C4).
Adjusting the Sample Playback Length
In any playback mode it is possible to adjust the sample playback length to either ignore unwanted sampled material or dead air, or to make a loop more musical. To do this: 1. Assuming the DELAY module is selected, use the PAGE buttons to select the display that says: SAMPLE START: 0.00 SECONDS This page determines the point from which the sample plays back. 2. Use the VALUE buttons to select the desired Start time. The start can be anywhere in the sample in 10 millisecond steps. Moving the sample start maintains the loop length unless the sample end moves past the loop end point. In this case, the loop will end at the actual sample end regardless of the loop duration. However, the duration value will remain intact, and will retake effect if the loop start is moved forward enough to allow the complete loop length. 3. Use the PAGE buttons to select the display that says: SAMPLE LENGTH: 1.55 SECONDS
This page determine the length of the sample playback. 4. Use the VALUE buttons to select the desired sample length time.
Adjusting the Sample Mix Parameters
The Mix module allows for adjusting the relative balance between the direct signal, and the recorded sample playback signal. 1. Press the MIX button. The display says: DIRECT LEVEL: 50 This page controls the level of the direct signal. 2. Press the VALUE buttons to select the desired direct signal level. The range is 0 to 99 (0 is off). 3. Press the PAGE UP button to select the next page. The display says: PREAMP LEVEL: 50 This page controls the samples output level. 4. Press the VALUE buttons to select the desired preamp signal level. The range is 0 to 99 (0 is off). 5. Press the PAGE UP button to select the next page. The display says: PLAYBACK LEVEL: 50 This page controls the samples output level. 6. Press the VALUE buttons to select the desired recorded Sample signal level. The range is 0 to 99 (0 is off).
CHAPTER 6 THE MIDI BUTTON
This Chapter describes how to set up the QuadraVerb GT for MIDI operation. The next Chapter covers how to modulate different parameters via MIDI continuous controllers. Please note that the MIDI button selects global settings that apply to all programs. Only the MIDI modulation options are stored with each program. All operations begin by pressing the MIDI button. The LED in the middle of the button will light. Use the PAGE buttons to select the following pages, and the VALUE buttons to select the parameter value for each page.

6.1 SELECT MIDI MODE

The display says: MIDI CHANNEL: OMNI There are two options. Omni In this mode, the QuadraVerb GT will respond to any data coming in from any MIDI channel. If youre using the QuadraVerb GT only with something like a MIDI Program Change Footswitch or Continuous Controller pedal, this is a hassle-free setting. If there are several devices connected to the MIDI line, you will need to assign each one to its own channel number, described next. 01-16 This selects a MIDI channel from 1 to 16. The QuadraVerb GT will respond only to information appearing on the selected channel. Example: If you want to control two independent QuadraVerb GTs from the same MIDI line, set each one to a different channel, such as 1 and 2, 5 and 10, 11 and 16, etc.
6.2 PROGRAM CHANGE ENABLE
The display says: MIDI PROGRAM CHANGE: ON There are three options. Off When off, the QuadraVerb GT will ignore any incoming program changes. On When on, the QuadraVerb GT will respond to incoming program change commands. There is a one-to-one correspondence between program change numbers and QuadraVerb GT programs (i.e., MIDI program 0 calls up QuadraVerb GT program 0, MIDI program 1 calls up QuadraVerb GT program 1, MIDI program 43 calls up QuadraVerb GT program 43, etc.). MIDI programs 100-127 will call up QuadraVerb GT programs 00-27 MIDI Weirdness Consumer Alert! Not all program changegenerating devices number their programs from 000-127; some number their programs from 001 to 128 (which would offset all program numbers by one), others group programs as banks of 8 or 16 programs, and so on. To figure out whats going on, set the QuadraVerbs MIDI Program Change parameter to on, select various programs on your program change-generating device, and see which programs are called up on the QuadraVerb GT. Table This enables a program change table (see next section) that lets you assign any QuadraVerb GT program number to any incoming program change number. Example: You can have MIDI program change 23 select QuadraVerb GT program 75. With Table selected, it is not necessary to have a one-to-one correspondence between QuadraVerb GT program numbers and incoming program change commands.
6.3 EDIT THE PROGRAM CHANGE TABLE
The display says: PROGRAM TABLE: 000 = 00 The lower left, three-digit number represents the incoming program change number. The lower right, two-digit number represents the QuadraVerb GT program that will be selected in response to the displayed program change number. In a new QuadraVerb GT, the two numbers should be equal up to MIDI program change number 100. At that point, the QuadraVerb GT program numbers start over again (i.e., 100=00, 101=01, 102=02, etc.). While this screen is showing, the PAGE UP button moves the cursor underneath the QuadraVerb GT program number. The PAGE DOWN button moves the cursor back under the MIDI program change number. The VALUE buttons change the selected parameter. To edit the program change table: 1. Select the incoming MIDI program change number with the VALUE buttons. 2. Press the PAGE UP button to move the cursor under the corresponding QuadraVerb GT program number. 3. Use the VALUE buttons to select the desired QuadraVerb GT program number. 4. To do more edits, press the PAGE DOWN button to return the cursor to the incoming MIDI program change parameter. 5. Repeat steps 1-4 until the table is completely edited.
