Page 54 Program Edit Mode The COMMON Page The Intonation Map parameter works just like the Global mode Intonation Map parameter, except the Intonation Map parameter on the Program Common page only applies to the current program. (The Global mode Intonation Map parameter applies to all programs.) See Editing Intonation Maps on page 9-12 for more details on intonation maps.
Page 55: Portamento Rate
Program Edit Mode The COMMON Page Portamento When the Monophonic parameter is set to “On”, the Portamento parameter appears. When the Portamento parameter is set to “On”, notes played in a monophonic Program can glide from the pitch of the previously played note to the pitch of the currently played note. Portamento is often used in synthesizer lead sounds, or to mimic acoustic instruments like violin and bass, where a pitch glide is achieved by sliding a finger along a vibrating string.
Page 56 Program Edit Mode The COMMON Page Out Pan Use the Out Pan parameter to adjust the left/right balance of the entire Program output signal (post-FX). Negative values pan the audio signal to the left channel, positive values to the right, and a value of zero pans to the center. Out Pan Mode When the Out Pan Mode is set to Fixed, the Out Pan position remains as defined with the Out Pan parameter, ignoring MIDI pan messages.
Page 57: Demo Song
Program Edit Mode The Arpeggiator (ARP) Page Demo Song The Demo Song parameter allows you to choose the demo song for the current program. The demo song is a short, pre‐programmed song that gives you a demonstration of the program in a musical context. You can play a program’s demo song in Program mode by simultaneously pressing the 0/MISC and ENTER buttons.
Page 58 Program Edit Mode The Arpeggiator (ARP) Page The SAVE ARP Soft Button If you have adjusted any Arpeggiator settings, you have the option of saving a new Arp Preset to a User location, where it will be available to use with other Programs and Multis. All settings on the ARP page are saved as part of the arp preset, except for the State and KeyRange parameters, which are stored with the Program/Multi.
Page 59 Program Edit Mode The Arpeggiator (ARP) Page In Classic mode, the ARP page will offer algorithmic options, as well as independent note- Shift, Velocity and Duration patterns. These patterns are editable. See Arpeggiator Classic Mode Parameters on page 3-26 for details on Classic mode parameters. In Step Sequencer mode, you can edit sequences step-by-step, specifying Note, Velocity, Duration and Beat for each step in a sequence.
Page 60: Limit Option
Program Edit Mode The Arpeggiator (ARP) Page Overplay: Notes are arpeggiated only when the Latch switch is turned on while notes are held. Overplay latches any keys that are being held when the Latch switch is turned on. Latched keys continue arpeggiating after they are released until the Latch switch is turned off.
Page 61 Program Edit Mode The Arpeggiator (ARP) Page Stop causes the Arpeggiator to stop when it reaches the shift limit. Reset causes the Arpeggiator to return to its original pitch and repeat the cycle of notes. Unipolar means that after playing up to the shift limit, the Arpeggiator begins shifting notes in the opposite direction, until it reaches the original pitch, where it reverses again.
Page 62: Shift Limit
Program Edit Mode The Arpeggiator (ARP) Page Arpeggiator Classic Mode Parameters Beats The Beats parameter sets the number of notes per beat. The tempo is based on quarter notes. Therefore, if you set Beats to 1/4, you will get one note per beat of the clock. At 1/16, you will get 4 notes per beat, and so forth.
Page 63 Program Edit Mode The Arpeggiator (ARP) Page Shift Patterns are most easily used and understood when triggered by only one key at a time. One way to prevent triggering from multiple keys is to use one of the Latch types 1NoteAuto, 1NoteAutoLow, or 1NoteAutoHi when using a shift pattern.
Page 64 Program Edit Mode The Arpeggiator (ARP) Page Play Order When the Shift Mode is set to Alg, Play Order appears. Play Order determines the order in which the arpeggiator plays notes. Played causes them to play back in the chronological order in which you played them. Upwards means that notes play in ascending pitch order.
Page 65 Program Edit Mode The Arpeggiator (ARP) Page With Velocity set to Fixed, all notes play with the same velocity. The Velocity Fixed field appears, which allows you to set a specific velocity. In Multi Mode, you can control the velocity in real-time by assigning a controller to destination 175 VelFixed. When you select Pattern, the Velocity Patt parameter will appear, allowing you to select a preset or user defined velocity pattern.

Page 67 Program Edit Mode The Arpeggiator (ARP) Page Note: For patterns with negative velocity values, if the velocity of the first played note is low enough that a pattern step could result in a velocity of zero, some notes may have a velocity of zero and therefore produce no sound.
Page 68 Program Edit Mode The Arpeggiator (ARP) Page Editing Duration Patterns You can edit the highlighted pattern by pressing the EDIT button. You can create a new user pattern by editing an existing pattern and saving it to a user ID. Each step can have a duration from 0-100% of the current arpeggiator Beats setting.
Page 69 Program Edit Mode The Arpeggiator (ARP) Page Arpeggiator Step Sequencer Mode Parameters In Step Sequencer mode, the ARP page will give you the ability to create a unique Arpeggiator pattern step-by-step. Select a parameter using the up/down navigation buttons. To change steps, select the Step# parameter, then press the left or right navigation buttons.
Page 70: The Cc Sequencer (Cc Seq) Page
Program Edit Mode The CC Sequencer (CC SEQ) Page Veloc (Velocity) Veloc (Velocity) values shift the velocity of each step up or down from the last latched note. Velocity can be shifted -127 to +127 from the original value of the last latched note. Durat (Duration) Durat (Duration) determines how long each step is sustained, based on the Beats value of each step.
Page 71 Program Edit Mode The CC Sequencer (CC SEQ) Page CC Seq Preset Use the CC Seq Preset parameter to recall factory or user created CC Sequencer settings. A CC Seq Preset contains settings for all of the parameters on the CC SEQ page (except for the State parameter, which is stored with the Program/Multi).
Page 72: Note Value
Program Edit Mode The CC Sequencer (CC SEQ) Page When the Sync parameter is set to Arp with Reset, the sequence begins playing only when the program’s arpeggiator is playing, and it restarts whenever it reaches the end of the sequence, or whenever the program’s arpeggiator restarts its sequence.
Page 73 Program Edit Mode The CC Sequencer (CC SEQ) Page Each of the four sequences uses the same settings for the State, Number Steps, Sync, Note Value, and MIDI Dest parameters. All other CC Sequencer parameters can be adjusted independently for each of the four sequences. Scale Use the Scale parameter to change the range of CC values sent by the sequence (in combination with the Scale Mod, Add, and Add Mod parameters).
Page 74 Program Edit Mode The CC Sequencer (CC SEQ) Page The selected physical controller will use values 0-127 to add -127 through 127 to the CC values sent from the sequence. MIDI CC Use the MIDI CC field to select a MIDI CC number and/or assigned program parameter to control with a CC Sequence.
Page 75: The Keymap Page
Program Edit Mode The KEYMAP Page The KEYMAP Page Use the Keymap Page to select keymaps for the current layer of the Program, as well as other keymap parameters. A keymap is a group of samples that can be played by the current layer. Keymap, Keymap 1, Keymap 2 Assign a keymap to the current layer.
Page 76 Program Edit Mode The KEYMAP Page The PC4 contains both stereo and mono samples. Keymaps designed for stereo use are labeled with names beginning with “Stereo” or ending in “Left,” “Right,” “L,” or “R.” For stereo keymap playback, set Stereo to “On” and assign corresponding Left and Right keymaps to Keymap 1 and Keymap 2 respectively.
Page 77: Timbre Shift
Program Edit Mode The KEYMAP Page Alt Method Each sample root in a keymap can have an alternate sample start point. The sample start points in the selected keymap can be varied between the original and alternate start point by using an assigned physical controller or other control source.

(Layers set to Off will still resonate any other strings that have been emulated.) If more than one layer in a program is set to play piano notes for the exact same velocity and key range, the FX preset will function the best if only one of those layers has the String Resonance parameter set to On.
Page 80: The Layer Page
Program Edit Mode The LAYER Page The LAYER Page Use the Layer page to set the current layer’s keyboard range, velocity range, and other layer specific parameters. Low Key, High Key Use the Low Key and High Key parameters to set the key range for the current layer. The Low Key and High Key parameters set the lowest and highest active notes for the current layer.
Page 81 Program Edit Mode The LAYER Page Bend The Bend parameter determines how Pitch bend control messages will affect the current layer. To apply the same Bend setting to the entire program, set the same value for each layer. When Bend is set to All, pitch bend is applied to all notes. When Bend is set to Key, pitch bend is applied only to held notes (pitch bend is not applied to notes held with the sustain pedal).
Page 82 Program Edit Mode The LAYER Page Enable, Enable Low, Enable High, Enable Sense Use the Enable parameters to determine when the layer will be active, based on the value of a physical controller or other control source. For details on using the Enable parameters with velocity, see “Low Velocity, High Velocity”...
Page 83: Sustain Pedal
On3 setting also enables the use of half damper pedal techniques when using a compatible continuous switch pedal (such as the Kurzweil KP-1H). On3 emulates the behavior of an acoustic piano’s sustain pedal by increasing the release portion of the current layer’s amplitude envelope as the pedal is pressed down, before becoming fully sustained.
Page 84 Program Edit Mode The LAYER Page When the Freeze Pedal parameter is set to Off, notes will not respond to freeze messages. When the Freeze Pedal parameter is set to On, any note that is played or is already playing when the destination 69 receives a value of 64-127 will sustain without decay until destination 69 receives a value of 0-63.
Page 85: The Wiring Algorithm (Alg) Page
Program Edit Mode The Wiring Algorithm (ALG) Page The Wiring Algorithm (ALG) Page The PC4’s algorithms are the core of VAST programs (Variable Architecture Synthesis Technology). Use the Wiring Alg page to select an algorithm and route DSP (digital signal processing) functions for the current layer.

The OUTPUT Page Use the Output page to adjust the left/right panning position and other panning settings for each layer.
Page 94: Pan Mode
Program Edit Mode The OUTPUT Page Crossfade and Crossfade Sense The Crossfade parameter lets you select a control source to fade the current layer’s amplitude from zero to maximum. When CrossFadeSense is Norm, the layer is at full amplitude when the Crossfade control is at minimum.
Page 95: Pan Table
Program Edit Mode The OUTPUT Page When Out Pan Mode is set to +MIDI, MIDI pan messages (MIDI 10) will shift the sound to the left or right of the Pan parameter setting. Message values below 64 shift it left, while those above 64 shift it right.
Page 96: The Amplitude Envelope (Amp Env) Page
Many factory ROM samples include a natural envelope, which is custom designed for each sample by Kurzweil engineers. A natural envelope contains more detail than a user envelope, and allow samples of acoustic instruments to sound more realistic.
Page 97 Program Edit Mode The Amplitude Envelope (AMP ENV) Page After the Attack1 segment is played, the Attack2 segment is played. The volume goes from the volume level set by Attack1, to the volume level set by Attack2. Use the two fields below the Attack2 parameter to set a time for Attack2 in seconds, and a volume level in percent.
Page 98 Program Edit Mode The Amplitude Envelope (AMP ENV) Page Values of seg1F, seg2F, and seg3F are forward loops. In each case, the amplitude envelope plays through the attack and decay sections, then loops back to the beginning of the first, second, or third attack segments, respectively.

Program Edit Mode The LFO+ Page The LFO+ Page Use the LFO+ page to adjust LFOs, ASRs, and FUNs for each layer. LFO Parameters LFOs are low-frequency oscillators, periodic (repeating) control sources. LFOs are used to repeatedly modulate a parameter based on the shape and frequency of an audio waveform. You can control the LFO rate in real time (which defines how frequently the LFO repeats) in Hz, or in note values in order to sync with the program tempo.
Page 103: Maximum Rate
Program Edit Mode The LFO+ Page Maximum Rate The MxRate parameter sets the fastest rate at which the LFO runs. Each LFO runs at the maximum rate when its RateCt parameter is set to ON, or when the control source assigned to RateCt is at its maximum value.
Page 104 Program Edit Mode The LFO+ Page Trigger The Trigger parameter defines the control source that triggers the attack segment of each ASR. When a switch control source is selected, the ASR is triggered when the control value changes from off to on. When a continuous control source is selected, the ASR is triggered when the control value changes from below its middle point to above its middle point.
Page 105 When the output of a FUN is used as a Mod control source, the -1 to +1 range of values is scaled based on the Depth setting of the Mod source. See the K2600 Musician’s Guide at kurzweil.com for more details and a description of each available FUN.

SW + SHP (Sawtooth + Shaper) This oscillator is capable of basic FM Synthesis. Its distinctive parameter is Pch Coar. This oscillator must come after the sound source in an algorithm (either keymap or oscillator) in order to hear the effect of Pch Coar, which can radically change whatever the oscillator receives as an input.
Page 115 Program Edit Mode Editing VAST Programs With KVA Oscillators PWM (Pulse Width Modulation) [Aliased (not recommended)] This oscillator’s distinctive parameter is PWM Wid, which adjusts pulse width from values of 1-99. With PWM Wid set to a value of 50, PWM produces a square wave. The further the PWM Wid parameter is set from 50, the narrower the pulse width becomes, changing the shape of the output waveform and thus altering the oscillator’s tonal quality.
Page 116 Program Edit Mode Editing VAST Programs With KVA Oscillators Use Of Keymaps and Natural Amplitude Envelopes With KVA Oscillators: Keymaps are important in layers using KVA oscillators, even though their samples are not usually heard in these layers (see the note below for exceptions). Keymap selection is important because the maximum amplitude set for each key in the keymap is applied to the oscillator.
Page 117: Editing Fm Layers
Program Edit Mode Editing FM Layers Editing FM Layers FM layers can be used to emulate classic FM synthesizers by using 6 Operators in 1 of 32 algorithms. FM layers also allow FM synthesis techniques to be combined with VAST synthesis features to create never before heard sounds.
Page 118 Program Edit Mode FM MAIN Page Use the Alg parameter to select 1 of 32 algorithms. Each algorithm changes how the Operators are connected to one another, determining which operators are heard as audio signals, and which are used as modulation sources. The algorithm diagram to the right of the Alg parameter shows each Operator as a numbered box, with lines between each operator to show how they are connected.
Page 119 Program Edit Mode FM MAIN Page Operator Envelope Generator Parameters Each Operator contains an envelope generator which controls the output level of the Operator. Use the Operator envelope generator parameters to control the output level of the Operator over time. For Operators in the bottom row of the Algorithm diagram, changes to the output level of the Operator are heard as changes in audio level (similar to an amplitude envelope).
Page 120: Fm Operator Page
Program Edit Mode FM Operator Page R4, L4 When a note is played and released, the Operator level begins to change to the level set by the L4 parameter. The R4 parameter determines the rate at which the Operator output level changes from its current level to the level set by L4.
Page 121 Program Edit Mode FM Operator Page Waveform Use the Waveform parameter to select a waveform for the oscillator of the selected Operator. In classic FM synthesis, sine waveforms are used. Using waveforms other than sine can be useful for easily creating more complex timbres. Input Source Use the Input Source parameter to select an input for the selected Operator.
Page 122 Program Edit Mode FM Operator Page When KeyVel Sensitivity is set to 7, the Operator level is the most sensitive to velocity. Notes with low velocities will set the Operator to a much lower output level. Key Rate Scaling Use the Key Rate Scaling parameter to adjust Key Rate Scaling for the selected Operator. Key Rate Scaling makes the Envelope Generator rates of the selected Operator faster as higher notes are played.

Detune Use the Detune parameter to adjust fine tuning for all Operators in the layer. This is useful for creating a chorus effect by applying different Detune values to multiple FM layers which are set to the same settings.
Page 127 Program Edit Mode FM Layer Page When Oscillator Key Sync is set to Off, the oscillator in each FM Operator does not reset its phase each time a note is played. In some programs this can be useful for adding subtle variations to each note played.

Page 134: Fm Alt Input Page
Program Edit Mode FM Alt Input Page FM Alt Input Page In classic FM synthesis, Operators containing sine wave oscillators are used to frequency modulate other Operators in various configurations in order to create complex timbres. FM layers allow you to use an alternate input for these Operators, allowing sources other than FM Operators to be used for modulation of other FM Operators.
Page 135 Program Edit Mode FM Alt Input Page 5. Try adjusting the Keymap Level Adjust parameter to find interesting timbres. If the Keymap level is too low, no modulation will be applied. If the Keymap level is too high, the Operator will create noisy timbres. Keymaps with complex or noisy timbres will more easily create noisy timbres when used as a modulation source, so for these Keymaps the Adjust parameter may need to be turned down.
Page 136 Program Edit Mode FM Alt Input Page Alt Input Source/Level Parameters Src Layer Use the Src Layer parameter to select another layer in the Program to use its audio output signal as a modulation source for FM Operators. The current Program must have more than one layer.
Page 137 Program Edit Mode FM Alt Input Page Depth Use the Depth parameter to set the maximum modulation depth of Source 1. When the Source 1 control source is at its minimum value, Source 1 will have no effect on the Alt Input source layer output level. When the Source 1 control source is at its maximum value, Source 1 will apply the amount of modulation set by the Depth parameter.
Page 138 Program Edit Mode FM Alt Input Page Vel Track Use the Vel Track parameter to modulate the amplitude of each note of the Keymap based on the MIDI velocity of each note played. Positive Vel Track values will progressively increase the amplitude for higher velocities. For example, with a positive Vel Track value, playing a velocity of 0 causes no change in amplitude, playing each velocity further above 0 increases the amplitude by the Vel Track amount.

Page 163 The Effects Chain Editor Effects Parameters XCouple (Cross Couple). In stereo effects, this controls how much of any signal being fed back is going to the channel opposite to the one where it first appeared. At 100%, all feedback from signals at the left input goes to the right channel and vice versa, causing a “spreading”...
Page 164 The Effects Chain Editor Effects Parameters Diff Scale scales the “diffusion“ of the early reflections, that is, how spread out they are as a group over time. At very low settings, the early reflections start to sound quite discrete, and at higher settings the early reflections are seamless.
Page 165: Complex Echo
The Effects Chain Editor Effects Parameters Hold is a switch that, when turned on, “locks” any signal currently in the delay and plays it until Hold is turned off. When Hold is on, no signal can enter the delay and Feedback is set to 100%.
Page 166 The Effects Chain Editor Effects Parameters Tap n Shapr adjusts the intensity of the shaper at each output tap. Range is 0.10 to 6.00 x. Tap n Pitch adjusts the frequency of the comb filter at each output tap. Range is C-1 to C8, in semitones.
Page 167 The Effects Chain Editor Effects Parameters Drive adjusts the input into each band. Increasing the drive will increase the effects. Range is -79.0 to 24.0 dB. Xfer adjusts the intensity of the transfer curves. Range is -100 to 100%. EQ Morpher This effect uses two four-band bandpass filters, A and B, and moves between them.
Page 168 The Effects Chain Editor Effects Parameters SmoothTime smooths the output of the expander’s envelope detector by putting a lowpass filter in the control signal path. Smoothing will affect the Attack or Release times only when this parameter is longer than one of the other times. The range is 0.0 to 228.0 ms. Signal Dly (Delay) puts a small delay in the signal relative to the sidechain processing, so that the compressor (or gate) “knows”...
Page 169 The Effects Chain Editor Effects Parameters Gates SC Input lets you select which input channel(s) will control the sidechain, which is responsible for opening and closing the gate. It can be set to L, R, or the average of the two channels, (L+R)/2.
Page 170 The Effects Chain Editor Effects Parameters Tap Pan sets the stereo position for a given tap’s output. The range is -100% for fully left, to 100% for fully right. Atk Time (attack time) is the time for the gate to ramp from closed to open (reverse if Ducking is on) after the signal rises above threshold, adjustable from 0.0 to 228.0 ms.
Page 171 The Effects Chain Editor Effects Parameters DynamRange (dynamic range) controls how many bits to remove from the signal data words. The lower the level, the greater the distortion. At 0 dB the hottest of signals will toggle between only two quantization levels, thereby producing a square wave. Every 6 dB added doubles the number of quantization levels, reducing the noise and getting closer to the original signal.
Page 172 The Effects Chain Editor Effects Parameters Filters Resonant Filter Frequency (or Freq) is the fixed resonant frequency of the filter. Its range is 16 to 8372 Hz. Envelope Filter Envelope Filter is a resonant filter whose center frequency can be made to vary according to the level of the incoming signal.
Page 173 The Effects Chain Editor Effects Parameters Retrigger is the input-signal threshold at which the envelope detector resets, so that it can trigger again. This parameter is only useful when it is set below the value of Trigger. Range is from -79 to 0 dB. Env Rate is the envelope detector decay rate.

The Effects Chain Editor Effects Parameters Highpass allows you to reduce the bass content of the distortion content in the smaller distortion effects that don’t have true parametric EQ. Range is 16 to 25088 Hz. Cab Preset selects from eight cabinet simulations which have been created based on measurements of real guitar amplifier cabinets.
Page 175 The Effects Chain Editor Effects Parameters Xover (Crossover) is the frequency at which high and low frequency bands are split and sent to separate rotating drivers. The range is 16 to 25088 Hz. Lo Gain and Hi Gain are the gains of the signal passing through the rotating woofer or tweeter, respectively.
Page 176: Tremolo And Autopan
The Effects Chain Editor Effects Parameters LoAccelCrv and HiAccelCrv are the shapes of the acceleration curves for the speakers. 0% is a constant acceleration.

Page 178: Ring Modulation
The Effects Chain Editor Effects Parameters Ring Modulation Ring modulation multiplies two signals (the “carrier” and the “modulator”) together to produce unusual, often non-harmonic, overtones. The Ring Modulator effect in the PC4 has two modes: “L*R” in which two mono signals are modulated together; and “Osc”, in which the input is stereo, and it is modulated with the sum of five waveforms that are generated from oscillators within the effect itself.
Page 179 The Effects Chain Editor Effects Parameters Crossover1 and 2 are the two Crossover frequencies at which the band-split filters split the signal into three bands. The two parameters are interchangeable: either may have a higher frequency than the other. Range is 16 to 25088 Hz. Pan [High/Mid/Low] sets the pan position for each band.

Most equipment responds to controller numbers 0, 32, or both. The Kurzweil K2600 it responds to controller 32, but is limited to 100 programs per bank.
Page 214 Multi Edit Mode MAIN Page parameters will automatically change to match the Bank and Program numbers of the Program that you select for Local Program. For example, if you choose Program 178, then MIDI Bank will change to 1 and MIDI Program will change to 50. Midi Program The MIDI Program parameter determines the MIDI Program change message that the currently selected Zone sends when the Multi is loaded.
Page 215: Velocity Offset
Multi Edit Mode MAIN Page Aux Bend Up / Dwn ST Use the Aux Bend Up / Dwn ST parameters to set the Aux Pitch Bend Up and Down ranges in semitones. Aux Pitch Bend is controlled by controller destination 21, the default destination for the Ribbon Controller.
Page 216: Velocity Curve
Multi Edit Mode MAIN Page Offset and Scale work together. If scaling takes the velocity out of the ballpark — for example, you want to set it to 300% but that puts all of your notes at maximum velocity — using a negative offset, say around -60, can make it possible to still play at different volumes, although your curve will still be a lot steeper than normal.
Page 217: Input Channel
Multi Edit Mode MAIN Page A keystroke in the current Zone whose velocity — after it has been scaled and offset — is below the minimum does not generate a Note On. Neither does a keystroke whose velocity after processing is above the maximum. These parameters are useful for “velocity switching”—having a key play different sounds depending on how hard you strike it.
Page 218 Multi Edit Mode MAIN Page external MIDI controller, and not from the PC4 keyboard. You can also choose “Any L+M” or “Any M” for the Input Channel setting. “Any L+M” and “Any M” will make the zone receive MIDI on any channel that an external device is transmitting. This is useful if you are using a single external MIDI controller and are not sure which channel it is transmitting on.

Page 222: Continuous Controllers
Multi Edit Mode CONTROLS Page If the Velocity parameter is set to Per Note, each note in the Key1-Key8 fields will use the velocity set by each of the 8 per note Velocity parameters. When the Controller parameter is set to a Key (Key1-Key12) and Mode is set to something other than “Off”...
Page 223 Multi Edit Mode CONTROLS Page Mode Continuous Controllers can be set to the following modes: Off, or MIDI CC. When Mode is set to Off, the controller is disabled for this zone. When Mode is set to MIDI CC, the controller can send MIDI control messages. Destination Use the Destination field to select a parameter to control.
Page 224 Multi Edit Mode CONTROLS Page Use the Add parameter to change the range of CC values sent by the controller (in combination with the Scale and Curve parameters). The Add parameter adds or subtracts from the CC values sent, changing the lowest and highest values sent by the controller. MIDI controllers are limited to sending values from 0-127, even if the Scale and Add parameters are set to produce values outside of this range.
Page 225 Multi Edit Mode CONTROLS Page The Reverse settings (Rvrs Linear, Rvrs Expand, Rvrs Compress, and Rvrs Crossfade) distribute values in the reverse compared to the regular version of these settings. For example,the Rvrs Linear setting distributes CC values 0-127 evenly over the range of the controller, with 0 at its highest position, and 127 at its lowest position.
Page 226 Multi Edit Mode CONTROLS Page When the Position Mode parameter is set to Absolute, the zero point for the Ribbon stays in the same physical location on the ribbon. By default this is the center of the Ribbon, although you can use the Center parameter to move the zero point. In Absolute mode, just touching the Ribbon affects the sound (unless you touch it at exactly the zero point).

Page 232 Multi Edit Mode CONTROLS Page If Shift Key is set to Last Note Played and no note is played, the default key is C. Each zone can have a different Shift Key, so you can have zones preprogrammed with the keys you want to use, or have them all in the same key, or just change the key in real time while you are playing.
Page 233 Multi Edit Mode FX Page FX Page The FX Page allows you to set Aux send levels for each channel, select two Aux FX Chains and Mod controls, and set Aux FX output routing. You can also enable or disable FX resources for each channel, which is useful for managing Insert FX usage.
Page 234 Multi Edit Mode FX Page Aux FX Channel The Aux FX Channel determines the MIDI channel that will be used for the Aux 1 and Aux 2 FX Chains. For example, if the Program in channel 2 uses the Chain “25 Basic Delay 1/8” as an Aux 1 Chain, then setting the Aux FX Channel to 2 allows the programs in all channels to send their signal to the Aux FX Chain “25 Basic Delay 1/8”.

Song Mode The MISC Page The MISC Page The MISC page contains miscellaneous sequencer parameters. The MISC page appears below: Quantize and Miscellaneous Parameters Control Chase A common shortcoming of many sequencers is that when you start a sequence at some point in the middle of sequence, the controllers remain at their current levels until the sequencer comes across a controller event.
Page 267: Strong Note
Song Mode The MISC Page Grid The grid parameter determines the resolution of quantization and the position of the grid points. Swing The Swing parameter determines the amount (in units of percent) of “swing” applied during quantization. Release The Release parameter determines whether or not note-off events are quantized. Metronome Parameters Metronome This parameter determines the recording modes in which the metronome plays.

Page 272: The Track Page
Song Mode The TRACK Page The TRACK Page Use the Track Functions page to perform track-based edit functions such as Erase, Copy, Bounce, Insert, Delete, Quantize, Shift, Transpose, Grab, Change, and Remap. For each function, there is a set of parameters to control how the function operates, and on what region of the selected track(s).
Page 273 Song Mode The TRACK Page Common Parameters for Track Functions Locate This parameter is available for every function on the TRACK page. It appears at the lower left hand corner of the page. The Locate bar, beat, and tick will change in real time during playback and recording to reflect the song’s current position.
Page 274: Soft Buttons On The Track Page
Song Mode The TRACK Page Value Range The left and right Value Range fields respectively determine the lowest and highest values in a range of MIDI Continuous Controller (CC) values that will be affected by the selected Track Function. Soft Buttons on the TRACK Page FROM TO is a quick way to define the region of time you intend to edit.
Page 275 Song Mode The TRACK Page Copy Use the Copy function to duplicate the selected events from the current track and place them in the same track or on another track, either merging with or overwriting existing events. If you do not want to copy all of the MIDI events in the defined range of time on the current track, use the Events parameter to select a specific MIDI event type you would like to copy.
Page 276 Song Mode The TRACK Page Bounce Use the Bounce function to move the selected events from the current track to another track, either merging with or overwriting existing events on the destination track. The Bounce function differs from the Copy function in that events on the source track are deleted. As on a multi-track tape recorder, Bounce will always put the copied events at the same place in time on the Destination Track that they were on the source track.
Page 277 Song Mode The TRACK Page Insert The Insert function is used to add blank time to the current song, modifying the song’s End point appropriately. The Insert function will affect all tracks. This is similar to splicing a piece of blank tape to an existing segment of recording tape. Location: Bars : Beats : Ticks Use the Location parameter to specify a bar, beat, and tick location in the destination track where the blank time will be inserted.
Page 278 Song Mode The TRACK Page Delete The Delete function is used to remove a region of time from the current song. This function is different from the erase function because not only does it remove the events from the selected time, it will delete the entire selected range of time from the song, modifying the song’s End point appropriately (on all tracks).
Page 279 Song Mode The TRACK Page Quantize Use the Quantize function to adjust the timing of Note events. Keep in mind that only Note events are quantized; other types of events, such as controllers, are not quantized. Quantize Amount: 0 to 100% The Quantize Amount parameter determines how much the selected Note events are moved towards grid locations.
Page 280 Song Mode The TRACK Page Shift The Shift function allows you to offset the existing MIDI events forward or backward in time any number of bars, beats and ticks. Events can not be shifted before Bar 1 : Beat 1 : Tick 0. Amount: Bars : Beats : Ticks The Amount parameter specifies the number of bars, beats, and ticks that the selected MIDI events are moved forward or backward in time.
Page 281 Song Mode The TRACK Page Transpose Use the Transpose function to change the MIDI Note numbers of the selected Note events. Semitone: -128 to 127 semitones An increment of one semitone represents a change of one MIDI Note number. You can transpose Note events only within the range of MIDI Note numbers 0 to 127.
Page 282 Song Mode The TRACK Page Grab Grab is similar to the Copy function, except that the Grab function allows you to copy selected events from tracks that exist in other songs in memory. Source Song: Song List Use the Source Song parameter to select a song to Grab. The source track is determined by the Track parameter displayed on upper right hand side of the page, selectable with the CHANNEL/LAYER/ZONE/TRACK buttons.
Page 283 Song Mode The TRACK Page Times: 1 to 127 The value selected for the Times parameter determines how many copies of the selected region are placed, one after another, in the destination track. Change The Change function is used to modify existing velocities, controller events, or other MIDI events on the current track.
Page 284 Song Mode The TRACK Page When the Change function is applied with Mode set to PosRamp, the selected velocity or controller values will gradually change over the region of time, defined by the locations set for the From and To parameters, from the original value to the new value determined by the Scale and Offset settings.

Page 300 Global Mode MAIN2 Page Intonation Map Most modern western music uses what is known as equal temperament. This means that the interval between each semitone of the 12 tone octave is precisely the same as every other semitone. However, many different intonation intervals have evolved over the centuries and across cultures and instruments, so equal temperament will not sound appropriate for certain styles of music.
