Chapter 1: Getting Started
If you are new to Auto-Tune, we encourage you to read this manual and work through the tutorials in Chapter 4. It's the quickest way to become familiar with what Auto-Tune 4 does and how it does it. If you are upgrading from a previous version of Auto-Tune, you will find that most of what youre already doing will continue to work in Auto-Tune 4, only better. To get up to speed quickly, just check out the new feature overview below and then refer to the detailed New Feature Quick Start Guide in Chapter 5, which will tell you everything you need to know to make use of Auto-Tune 4's new capabilities.

So what exactly is Auto-Tune 4?
Auto-Tune 4 is a precision tool for correcting intonation errors or creatively modifying the intonation of a performance. Auto-Tune 4 employs state-ofthe-art digital signal processing algorithms (many, interestingly enough, drawn from the geophysical industry) to continuously detect the pitch of a periodic input signal (typically a solo voice or instrument) and instantly and seamlessly change it to a desired pitch (defined by any of a number of userprogrammable scales or through the use of graphical editing tools.). To take maximum advantage of the power of Auto-Tune 4, you should have a basic understanding of pitch and how Auto-Tune 4 functions to correct pitch errors. This chapter presents basic terminology and introduces AutoTune 4s operating paradigm, giving you information you need to use it effectively.

A little bit about pitch

Pitch is typically associated with our perception of the highness or lowness of a particular sound. Our perception of pitch ranges from the very general (the high pitch of hissing steam, the low pitch of the rumble of an earthquake) to the very specific (the exact pitch of a solo singer or violinist). There is, of course, a wide range of variation in the middle. A symphony orchestra playing a scale in unison, for example, results in an extremely complex waveform, yet you are still able to easily sense the pitch. The vocalists and the solo instruments that Auto-Tune 4 is designed to process have a very clearly defined quality of pitch. The sound-generating mechanism of these sources is a vibrating element (vocal chords, a string, an air column, etc.). The sound that is thus generated can be graphically represented as a waveform (a graph of the sounds pressure over time) that is periodic. This means that each cycle of waveform repeats itself fairly exactly, as in the periodic waveform shown in the diagram below:
Because of its periodic nature, this sounds pitch can be easily identified and processed by Auto-Tune 4. Other sounds are more complex. This waveform:
is of a violin section playing a single note in unison. Our ears still sense a specific pitch, but the waveform does not repeat itself. This waveform is a summation of a number of individually periodic violins. The summation is non-periodic because the individual violins are slightly out of tune with respect to one another. Because of this lack of periodicity, Auto-Tune 4 would not be able to process this sound.

How Auto-Tune 4 corrects pitch
Auto-Tune 4 provides two separate and distinct ways to approach pitch correction: Automatic Mode and Graphical Mode. The basic functionality of each is described below.

Automatic Mode

Auto-Tune 4s Automatic Mode works by continuously tracking the pitch of an input sound and comparing it to a user-defined scale. The scale tone closest to the input is continuously identified. If the input pitch exactly matches the scale tone, no correction is applied. If the input pitch varies from the desired scale tone, an output pitch is generated which is closer to the scale tone than the input pitch. (The exact amount of correction is controlled by the Retune Speed parameter, described below and in Chapter 3.) SCALES The heart of Automatic Mode pitch correction is the Scale. Auto-Tune 4 lets you choose from major, minor, chromatic or 26 historical, ethnic and microtonal scales. Individual scale notes can be bypassed, resulting in no pitch correction when the input is near those notes. Individual scale notes can also be removed, allowing a wider range of pitch correction for neighboring pitches. The scale can be detuned, allowing pitch correction to any pitch center. For added flexibility, you can also select the target pitches in real time via MIDI from a MIDI keyboard or a pre-recorded sequencer track.
RETUNE SPEED Auto-Tune 4 also gives you control over how rapidly, in time, the pitch adjustment is made toward the scale tone. This is set with the Retune Speed control (see Chapter 3 for more details). Fast Speed settings are appropriate for short duration notes and for mechanical instruments, like an oboe or clarinet, whose pitch typically changes almost instantly. A fast enough setting will also minimize or completely remove a vibrato, as well as produce the infamous Cher effect. Slow Speed settings, on the other hand, are appropriate for longer notes where you want expressive pitch gestures (like vibrato) to come through at the output and for vocal and instrumental styles that are typified by gradual slides (portamento) between pitches. An appropriately selected slow setting can leave expressive gestures intact while moving the average pitch to the correct tonal center. VIBRATO Auto-Tune 4 can also apply a vibrato to the input sound. You can program the vibrato rate along with individual vibrato depths for pitch, amplitude (loudness) and formant (resonant frequencies). You can also specify delayed vibrato with independently programmable onset delay and onset rate. By combining a fast Retune Speed setting with Auto-Tune 4s Vibrato settings, you can even remove a performers own vibrato and replace it with Auto-Tune 4s programmed vibrato, all in real time. Also, unusual combinations of Vibrato Waveform, Rate and Depth settings can be used for some interesting special effects. AN EXAMPLE OF AUTOMATIC MODE CORRECTION As an example, consider this before-and-after graphic representation of the pitch of a vocal phrase that contains both vibrato and expressive gestures.

THE EDIT SCALE DISPLAY The Edit Scale Display is used to create custom scales or to modify any of the preset scales. Edits made using this display are associated with each scale. That is, each scale retains its own edits independent of the other scales. For example, if you select C Major and Remove or Bypass certain notes and then change to C Minor and make other edits, when you return to C Major your previous edits associated with C Major will be restored. The Edit Scale window displays each note of the currently selected scale in the currently selected key. If the selected scale includes more than twelve notes, Up and Down arrows will appear to allow scrolling through all of the available notes. Beside each note name are two buttons: a Bypass button and a Remove button. Click on a button to toggle its state. The button will light to indicate that its mode is active. If neither of these buttons are lit, Auto-Tune 4 treats this note as a normal scale note, i.e., when the input pitch is close to this note, Auto-Tune 4 will correct the pitch to this note at the rate set by the Retune Speed control.
If the scale selected in the Scale popup contains exactly 12 notes (e.g., Chromatic, Pythagorean, Meantone Chromatic, Just, etc.), the Virtual Keyboard (see below) will be active and any edits to the scale notes made in the Edit Scale Display will also be reflected on the Virtual Keyboard. NOTE: Although Auto-Tune 4 allows setting scale note behaviors in individual octaves, any edits made via the Edit Scale Display will affect all octaves. To edit notes in individual octaves, use the Virtual Keyboard. BYPASS If the Bypass button is lit, when the input pitch is close to this note the input will be passed through with no correction. Why set Scale notes to Bypass? There are two main reasons to set one or more scale notes to Bypass. 1. If a performance includes pitch gestures around one or more specific notes that you want to preserve with no modification whatsoever, you can set just those notes to Bypass. This lets Auto-Tune 4 correct any pitch problems elsewhere in the scale but passes everything near the bypassed notes completely unprocessed. 2. If a performance contains only a single error, you can set all notes to Bypass except the one sour note. Auto-Tune 4 will then pass the entire performance through unprocessed except for the sour note, which will be corrected. REMOVE If the Remove button is lit, then the note is simply removed from the current scale. For example, selecting the Chromatic scale and then setting C#, D#, F#, G#, A# to Remove would cause a C Major scale to remain. In that case Auto-Tune 4 would always retune the input to the closest note of the C Major scale. Why set Scale notes to Remove? To understand why it is sometimes necessary to set even correct scale notes to Remove, lets look again at the example from Chapter 1.

This phrase is in D Major and, if all the pitch errors were no greater than about 49 cents, would work fine with a standard D Major scale (D, E, F#, G, A, B, C# ). However, the pitch error of three semitones at the end of the last note is so large that with B and C # present in the Scale, as the pitch fell, AutoTune 4 would see first C# and then B as the target pitch and therefore allow the error to remain. With C# and B removed from the Scale, Auto-Tune 4 continues to see D as the target pitch for the entire duration of the note and therefore pulls the phrase up to the correct pitch.
CENTS The number in the Cents column is the associated notes interval, in cents, from the root note of the scale. Its provided for reference purposes and to help you choose which notes of a microtonal scale to include or remove.
SET ALL Clicking this button sets all notes in the current scale to Scale Notes in all octaves. This function is useful as a Reset button to instantly erase all previous Remove and/or Bypass settings and reset an edited scale to its default state.
REMOVE ALL Clicking this button sets all notes in the current scale to Remove in all octaves. BYPASS ALL Clicking this button sets all notes in the current scale to Bypass in all octaves.
SET MAJOR SCALE/SET MINOR SCALE When any scale that includes more than seven notes (i.e., any non-diatonic scale) is selected, the Set Major Scale and Set Minor Scale buttons will appear. Clicking on either of these buttons will Remove all notes from the scale except for those notes closest to the notes of a traditional diatonic major or minor scale (depending, of course, on which button you clicked).
VIRTUAL KEYBOARD The Virtual Keyboard displays Auto-Tune 4s pitch detection range and acts as a realtime display of the currently detected pitch, a display of the current Scale settings, and as a tool for setting target note behaviors in specific octaves. NOTE: The keyboard is only active for scales with exactly twelve notes. It will be grayed out (hence inactive) when any other scale is selected. But wait! you might be thinking, I want to edit Major and Minor scales in individual octaves and the keyboard is grayed out when I select either one. No problem. Simply select Chromatic, then use the Set Major or Set Minor button to set up the scale of your choice and edit away.
KEY COLORS The color of the keys of the Virtual Keyboard indicate their current state as follows:

COLOR STATE

Blue White or Black Invisible Brown

IMPORTANT NOTE: If you will not be defining Auto-Tune 4s target pitches via MIDI, be sure that the Target Notes Via MIDI button is off. If it is left on and no MIDI note data is present, Auto-Tune 4 will pass through all audio unprocessed giving the impression that Auto-Tune 4 is not functioning. LEARN SCALE FROM MIDI In most cases, you will probably tell Auto-Tune 4 which notes to correct to using the Edit Scale Display and/or the Virtual Keyboard. However, there may be occasions when it is not clear exactly what key a melody line is in, or where the line has too many accidentals to fit comfortably into a conventional scale. For those occasions, the Learn Scale From MIDI function allows you to simply play the line into Auto-Tune 4 from a MIDI keyboard or sequencer track and let Auto-Tune 4 construct a custom scale containing only those notes that appear in the line. To use the Learn Scale From MIDI function, ensure that the desired MIDI source is routed to Auto-Tune 4 and then click the Learn Scale From MIDI button. Its associated LED will light and the Edit Scale display will automatically be set to a chromatic scale with all of the notes set to Remove. Now simply play the melody to be corrected from your keyboard or sequencer. Tempo and rhythm dont matter, so take your time and make sure you dont play any wrong notes. As each note is played, the corresponding Remove button in the Edit Scale Display is turned off (adding that note to the scale as a Scale Note). Assume, for example, that your melody starts with D, B, and then A. After playing those notes the display would look like this:
When you have played the entire melody, press the Learn Scale From MIDI button again to end the process. The Edit Scale Display will now contain a scale containing only those notes that appeared in your melody. If you happen to make an error during note entry, or want to try again for any other reason, simply click the Learn Scale From MIDI button and start the process again. NOTE: When you start the process by pressing the Learn Scale From MIDI button, all notes are first Removed from the chromatic scale in preparation for adding just the notes you play. If you then press the Learn Scale From MIDI button again without playing any notes, you will be left with a chromatic scale with all notes removed. In this state, Auto-Tune 4 will pass all notes with no correction applied. So dont do that. ANOTHER NOTE: We realize that there is some possibility of confusion between the Learn Scale From MIDI function and Target Notes Via MIDI function described above. To clarify: Target Notes Via MIDI is used to specify target pitches in real time while pitch correction is occurring, while Learn Scale From MIDI is used in advance of correction to create a custom scale. OCTAVE AS PLAYED/ ALL OCTAVES For both of the MIDI functions (Learn Scale from MIDI and Target Notes via MIDI), you can now choose whether you want incoming MIDI notes to affect all octaves or just the notes in the specific octaves in which they are played. Simply click the desired button. The associated LED will light to indicate your choice. SCALE DETUNE The Detune parameter allows you to change the pitch standard of Auto-Tune 4 from the default A = 440Hz. The value is set in cents (100 cents = 1 semitone). The range of adjustment is from -100 to +100 cents. For convenience, the detune amount is also displayed in Hertz relative to A440. The Detune function can be used to tune a vocal performance to some irreparably out-of-tune instrument (a piano or organ, for example), or to allow correction to other than the conventional 440Hz standard.

NOTE: As mentioned above, although we perceive vibrato primarily as a variation in pitch, in most cases there is also matching (though more subtle) variations in amplitude and timbre. Setting Auto-Tune 4s Retune Speed to 0 will remove an existing vibratos pitch variation, but the amplitude and timbral variation will remain. If you then apply a new vibrato using Auto-Tune 4s Vibrato section, the results may be less than convincing. Auto-Tune 4s Vibrato section is more often useful for adding a vibrato to an input that originally had none, or for various special effects.
THE PITCH CHANGE INDICATOR The Pitch Change Indicator shows you how much the pitch is being changed, measured in cents (100 cents = one semitone). For example, if the indicator bar has moved to the left to -50, it indicates that the input pitch is 50 cents too sharp and Auto-Tune 4 is lowering the pitch by 66 cents to bring the input back to the desired pitch. HOLD BUTTON Clicking and holding the Hold button while Auto-Tune 4 is processing audio will freeze both the Pitch Tuning display and the blue Detected Pitch indication on the keyboard for as long as you hold down the mouse button. This is useful for figuring out exactly whats going on with a particular note in a performance that would otherwise pass too quickly to see.

Graphical Mode Controls

The Playback Controls
TRACK PITCH The Track Pitch function is used to detect the pitch of the audio to be processed so that it can be displayed on the Pitch Graph Display. Locate the desired audio and press the Track Pitch button. Its LED will flash to indicate that Auto-Tune is waiting for audio. Next, start playback of the audio. (The Track Pitch LED will light steadily.) When all of the audio you want to correct has played, stop playback. Track Pitch is automatically deactivated and the detected pitch is displayed on Pitch Graph Display. NOTE: After tracking, the pitch display will automatically scale in such a way as to include all of the tracked audio. ANOTHER NOTE: If the length of the audio to be processed exceeds the currently set size of the buffer as set in the Options dialog, playback will stop when the buffer is full. If this happens, increase the buffer size as necessary. 33
CORRECT PITCH After you have used the graphical tools (as described below) to create a target pitch contour, this button is used to apply the pitch correction to the audio. In all cases, pressing the Correct Pitch button and then starting playback will cause the pitch correction to be applied to the audio. In some host applications, starting playback when the Pitch Graph contains any yellow pitch correction contour will automatically engage the Correct Pitch function. Check your Auto-Tune 4 Read Me file for details.
THE PITCH GRAPH DISPLAY The Pitch Graph displays the pitch contour of the audio to be processed as well as the target pitch contour objects that you create. On this display, the vertical axis represents pitch (with higher notes towards the top) while the horizontal axis represents time. NOTE: As explained in the Options section, you can select from three different color schemes for the Pitch Graph Display. In the descriptions below we will refer to the colors that appear in the Classic scheme. The red curve represents the original pitch contour of the input track, while the desired target pitch or pitch contour is indicated in yellow.

THE REDO BUTTON The Redo button becomes active whenever you have executed at least one Undo. Clicking the Redo button once will redo the most recent undone change. If you have executed multiple undos, you can continue to click Redo to redo additional changes up to the limit that you set in the Options dialog. THE CUT AND COPY BUTTONS The Cut and Copy buttons become active whenever a pitch contour object is selected. Cut removes selected objects. Both Cut and Copy copy selected objects to the Auto-Tune 4 clipboard. You can then paste the objects elsewhere in the Pitch Graph display. THE PASTE BUTTON The Paste button becomes active whenever an object has been Cut or Copied to the clipboard. Clicking Paste places the contents of the clipboard in the center of the current Pitch Graph view. NOTE: Since only one pitch contour object (line or curve) can exist at any time point on the Pitch Graph, any object(s) that previously existed at the time where an object is Pasted will be deleted. Hence, before you press Paste, be sure that the Pitch Graph view does not contain any pitch contour object(s) that you want to keep. THE SELECT ALL BUTTON The Select All button causes all pitch contour objects, whether currently visible on the Pitch Graph view or not, to become selected. KEYBOARD EQUIVALENTS Some host applications support the following keyboard command equivalents for the above Edit Buttons. Others reserve these commands for their own use. Consult your host applications manual for details (or just try them and see if they work). Command/Control-Z Command/Control-X Command/Control-C Command/Control-V Command/Control-A undo cut copy paste select all
THE MAKE CURVE BUTTON The Make Curve button is enabled whenever there is any red input pitch contour data present in the Pitch Graph (whether it is displayed in the current Pitch Graph view or not). Pressing the Make Curve button causes yellow target pitch contour objects (curves for short) to be created from the input pitch contour data. These curve objects can then be dragged and stretched for very meticulous pitch correction. This is the central technique of Auto-Tune 4s Graphical Mode and is described in more detail in Chapter 4. NOTE: If a range of time has been selected by using the I-beam Tool, the Make Curve button works only in the selected time range. Otherwise it works on all red pitch data. THE MAKE AUTO BUTTON The Make Auto button is enabled whenever there is any red input pitch contour data present in the Pitch Graph (whether it is displayed in the current Pitch Graph view or not). Pressing the Make Auto button causes yellow target pitch contour objects (curves for short) to be created from the red input pitch contour data. The yellow curve(s) created by the Make Auto function is a precise representation of the pitch correction that would result from processing the tracked input pitch through the current settings of Auto-Tune 4s Automatic Mode. These include the Automatic Modes Key and Scale selections, the Edit Scale settings, the Improved Targeting mode (if selected), and the Scale Detune, Retune Speed and Vibrato settings. NOTE: If a range of time has been selected by using the I-beam Tool, the Make Auto button works only in the selected time range. Otherwise it works on all red pitch data. ANOTHER NOTE: If you are adding pitch variation using the Automatic Modes Vibrato function, the variation in pitch will be visually reflected in the yellow curve when you Make Auto. However, since there is no easy way to visually represent specific changes in amplitude or formant, if you have used the Automatic Modes Vibrato function to introduce amplitude and/or formant variation, the Make Auto curve will be blue rather than yellow to remind you that these elements will be introduced into your Graphical Mode output. YET ANOTHER NOTE: The Automatic Mode Tracking control is not involved in the Make Auto function. In Graphical Mode, the input pitch has already been determined, (i.e., the red input pitch contour), hence the Automatic Mode Tracking setting is not needed for the Make Auto computation.

Once you have used the Make Auto function to create a yellow (or blue) target pitch curve, setting the Graphical Mode Retune Speed to 0 and clicking Correct Pitch will result in exactly the same output as you would have gotten by processing the audio through Automatic Mode. Alternatively, you can adjust the Retune Speed or further edit the yellow curve using any of the Graphical Mode tools to get precisely the effect you want. If you arent satisfied with the results of the Make Auto function, simply switch to Automatic Mode, modify any of the settings as desired, and then return to Graphical Mode and click Make Auto again. NOTE: In addition to its use as a Graphical Mode correction tool, the Make Auto function can also be used to provide an informative visual representation of the results of Automatic Mode settings. If there are times when youd prefer to use Automatic Mode, but cant quite zero in on the ideal settings, examining the results of various settings with the Make Auto function can give you a visual picture of exactly whats going on. This will often make it readily apparent which Automatic Mode settings need to be changed to give your desired results. STILL ANOTHER NOTE: One potentially confusing aspect of the Make Auto function is the relationship between the Automatic Mode Retune Speed setting and the Graphical Mode Retune Speed setting. To summarize: The Automatic Mode Retune Speed controls how the input audio would be processed in Automatic Mode. Changing this setting will change the shape of the yellow curve that will be created by the Make Auto function. The Graphical Mode Retune Speed controls how quickly the pitch of the input audio will be changed to that of the yellow target pitch curve by the Correct Pitch function. As mentioned above, to precisely duplicate the results of Automatic Mode, set the Graphical Mode Retune Speed to 0. VIBRATO SCALING The purpose of this function is to quickly and easily change (either increasing or decreasing) the amount of an existing vibrato, while preserving the original shape and character of the vibrato. To use this function, select the I-beam tool and highlight the range of audio youd like to edit. When a range of audio is selected, the Make Vibrato Curve button becomes active. Set the desired amount of change using the Scale Vibrato Amount knob and then click the Make Vibrato Curve button to create a correction curve. Audition the result. If its not exactly what you wanted, click Undo and try again. 42

13. Select the Scissors Tool and click on an existing line or curve to break it in two at that point. A stacked pair of anchor points will be created at the point you click. Select the Arrow Tool again and use it to drag each of the new end points in turn to new positions. 14. Select one or more objects and play with the Edit Buttons (Undo, Cut, Copy, Paste, Select All). This would also be a good time to see if the Edit Button keyboard equivalents work in your host application: Command/Control-Z Command/Control-X Command/Control-C Command/Control-V Command/Control-A undo cut copy paste select all

Tutorial 5: Precision

This tutorial is actually more of a demonstration to show the extraordinary precision with which Auto-Tune 4 can track and correct intonation problems. If this doesnt sound interesting, feel free to proceed to Tutorial 6 below. (By this time, well assume youre comfortable loading files and calling up Auto-Tune 4.) 1. Arrange the files C2 Ahhh v3 and C2 Ohhh v1 so that they are on separate tracks and can be played simultaneously. 2. Assign a separate instance of Auto-Tune 4 to each of the two tracks and select Automatic Mode for each of them. 3. In each Auto-Tune 4, set the Retune slider to 0. 4. In each Auto-Tune 4, set the Key pop-up to B-flat. 5. Do whatever your host application requires to bypass both instances of Auto-Tune 4. 6. Play back the files so you can hear them together without processing. Believe it or not, these vocal samples from a sample CD are supposed to be the same pitch. Yikes! 7. Now enable Auto-Tune 4 on each of the tracks and play the files again. If youve done everything right, you will hear the samples so well in tune that they sound like one voice.
Tutorial 6: The Make Curve Function
This tutorial will introduce you to the Make Curve function. The Make Curve function gives you by far the most precise control over pitch accuracy and inflection. 1. Setup to process the file Crowd All through Auto-Tune 4. 2. Select Graphical Mode. 3. Press the Track Pitch button. 4. Play the Crowd All file. 5. Select the Magnifying Glass Tool and drag out a box on the Pitch Graph that encloses the red curve for the -gether part of the last word, together. You will see something like the following:
6. Use the I-beam Tool to drag a selection of -gether in the Pitch or Envelope Display. The result will be something like the following:
7. Click the Make Curve button. Auto-Tune 4 will compute a new yellow curve object from the existing pitch data. (The new curve may be difficult to see at first because it will exactly overlay the red curve.) Click the I-beam Tool on the background of the Pitch Graph to cancel the area selection. 8. Both anchor points of the new curve will be selected. Select the Arrow Tool and click precisely on the left end of the curve to select only the left anchor point (youll know youre over the anchor point when the cursor changes to the four-pointed arrow cursor). Drag this straight up, stretching the curve so it is centered around the D3 graph line. (If you press Option/Alt on your keyboard before clicking the anchor point, your movement will be constrained to the vertical, assuring that you maintain the time relationship of the curve.) 9. Move the Arrow Tool over the body of the yellow curve so that the cursor changes to the horizontal bar. Press and hold Option/Alt on your keyboard (to constrain movement to the vertical) and click and drag the curve straight down so it is centered on the C3 graph line. The Pitch Graph should now appear as follows:

VIRTUAL KEYBOARD The Virtual Keyboard displays Auto-Tune 4s pitch detection range and acts both as a display of the current Scale settings and as a tool for setting target note behaviors. NOTE: The keyboard is only active for the Major, Minor and Chromatic scales. KEY COLORS: The color of the keys of the Virtual Keyboard indicate their current state as follows: Blue: The currently detected input pitch White or Black: Scale Note Brown: Bypass Invisible: Remove KEYBOARD EDIT: These buttons are used to select which state (Remove or Bypass) will be toggled when you click on a key. When Remove is selected, clicking on any key that is not currently set to Remove will set that key to Remove. Clicking on any key that is currently set to Remove will set that key to a Scale Note. When Bypass is selected, clicking on any key that is not currently set to Bypass will set that key to Bypass. Clicking on any key that is currently set to Bypass will set that key to a Scale Note. NOTE: In the descriptions above, clicking on a key refers to pressing the mouse button down and then releasing it. The edit action is executed when the mouse button is released. Therefore, if the Momentary button is Off (see below), dragging across the keyboard highlights each key in turn, but it is only when you release the mouse button that the resulting key will change state. MOMENTARY: When this button is not On (i.e., its LED is not lit), any edits made to the keyboard will latch - i.e., clicking a key will change its state and the key will retain that state until some other action causes it to change. When the button is On (i.e., its LED is lit), keyboard edits are only active for as long as the mouse is held down on a key. Pressing and holding the Shift key on your keyboard will temporarily toggle the state of the Momentary button. A TIP: The main purpose of the Momentary function is to allow you to deal easily with specific individual events in a performance. However, you can also use it to play the target melody notes in real time. To do this, set the scale to Chromatic and use the Scale Edit window Remove All button to remove all notes from the scale. Set Keyboard Edit to Remove and Momentary to On. Now use your mouse to play the target melody on the keyboard. Its not as easy as Target Notes via MIDI, but if you dont have a MIDI controller handy, itll do in a pinch.
