Parameters 58

NameTypeRangeBehavior
Attackknob0% – 100%Time for the sound to reach peak level; uses a logarithmic scale from 0 to 9 seconds; is a modulation target.977
Beat Countmenu_setting1 – 512Specifies the number of beats in the clip/slicer WAV for clock synchronization; Auto attempts auto-detection.977
Beat Syncmenu_settingControls whether a time-based value is measured in musical intervals (synced to clock) or as a percentage. On the Delay FX it switches delay time between musical divisions (1/64 ... 1 bar) and a 0-100% value; Clip-mode pads and the LFO offer the same beat-synchronization choice.977
Brightnessmenu_settingControls the brightness of the display screen.977
Compressormenu_settingWhen set to On, applies a compressor to the signals sent to Out 1 and 2. Pads mapped to Outs 3-6 bypass the compressor.977
CutoffknobSets the delay filter cutoff; positive values apply high pass, negative values apply low pass; is a modulation target.977
Dampingknob0% – 100%Controls reverb damping; higher values shorten the reverb tail; is a modulation target.977
Decayknob0% – 100%Time from initial peak to sustain level; uses a logarithmic scale from 0 to 38 seconds; is a modulation target.977
Delayknob0% – 100%Sets delay length; when Beat Sync is on uses musical intervals (1/64 to 1 bar); when off uses 0–100%; is a modulation target.977
Densityknob0% – 100%Controls number of grains per second; higher values create more overlapping grains at the cost of processor load.977
Excl Groupmenu_settingAssigns the pad to an exclusive group (A–D); triggering any pad in the group stops all others. Excl X disables exclusive behavior.977
Feedbackknob0% – 100%Controls the amount of echo regeneration in the delay; is a modulation target.977
Filterknob-100% – 100%Applies either a low pass filter (negative values) or a high pass filter (positive values) to the pad; is a modulation target.977
Zones
Low Pass
High Pass
  • Low Pass -100–0%Negative values apply a low pass filter to the pad audio.977
  • High Pass 0–100%Positive values apply a high pass filter to the pad audio.977
Gainmenu_settingRecording setting: adjusts the input gain so the signal to be recorded reaches a good level without clipping (the VU meters show the level). Range -96.0 dB to +20.0 dB.977
Grain Sizeknob0% – 100%Sets the duration of each grain; 0% is about 20 ms, 100% is about 1 second.977
Interpmenu_settingSelects Normal or High Quality interpolation for chromatic pitch shifting; HighQ reduces aliasing but uses more processor resources.977
Launch Modemenu_settingControls how pad playback starts and stops: Trigger (plays to end), Gate (plays while held), or Toggle (plays until next trigger).977
Lengthknob≥0sampleWhen Loop Mode is None, determines how many samples play past the Start point; is a modulation target.977
Levelknob-96dB – 12dBAdjusts the loudness level of the pad; is a modulation target.977
LFO BeatSynswitchWhen ON, synchronizes the LFO wave cycle to the clock and changes LFO Rate to use beat/measure divisions instead of percentage.977
LFO Depthknob0% – 100%Sets the amplitude of the LFO wave; is a modulation target.977
LFO Rateknob0% – 100%Controls LFO frequency (about 0.1–12 Hz when BeatSync is off; beat/measure divisions when on); set to 0 to stop the LFO; is a modulation target.977
LFO TrigswitchWhen ON, the LFO restarts from the beginning each time the pad is triggered.977
LFO Wavemenu_settingSets the waveform shape for the pad's LFO: Saw, Reverse Saw, Triangle, Positive Triangle, Sine, Positive Sine, Square, Positive Square, or Random.977
Loop EndknobSample position where looping ends (forward) or begins (reverse); read from and saved to WAV smpl tag; is a modulation target.977
Loop Fadeknob0% – 100%Sets the crossfade overlap length at loop points as a percentage of the loop length; does not work with reverse looping.977
Loop Modemenu_settingControls looping direction: None (one-shot), Forward (loops between Loop Start and Loop End), or Bidirect (bounces back and forth).977
Loop Startknob≥0sampleSample position where looping begins (forward) or ends (reverse); read from and saved to WAV smpl tag; is a modulation target.977
MasterVolknobControls the master output volume sent to Out 1 and Out 2; default is 80% at power on.977
MIDI Chanmenu_settingAuto-sampler setting: the MIDI channel used to send out notes that drive the external instrument being sampled. Distinct from a pad's MIDI In listen channel. Range 1 to 16.977
MIDI Inmenu_settingAssigns a MIDI channel (Ch1–Ch16 or None) to control this pad chromatically or by slice; multiple pads may share a channel.977
Note Lengthmenu_settingAuto-sampler setting: in seconds, the length of time the note gate is held on while recording each sampled note. Range 1 to 60.977
Outputmenu_settingRoutes the pad audio to a selected stereo pair or mono output jack.977
Pad Notemenu_settingSpecifies which MIDI note on the MIDI Pads channel triggers this pad; C#-1 maps to MIDI note 0.977
Panknob-100% – 100%Controls the left/right stereo position for pads routed to stereo outputs; not a modulation target.977
Pan Rndknob0% – 100%Randomly pans individual grains across the stereo field; higher values create a wider stereo spread.977
Pitchknob-24semitone – 24semitoneAdjusts the pitch of the pad up or down; is a modulation target.977
PlayThruswitchWhen ON, playback continues past the end of the triggered slice to the end of the file; when OFF, stops at the slice boundary.977
Poly Modemenu_settingSets maximum simultaneous voices for the pad (Mono through Poly8 or PolyX); draws from the shared 24-voice pool; does not apply to Granular pads; Gate-triggered pads are monophonic.977
Predelayknob0% – 100%Delays the signal before reverb is applied, analogous to distance from the walls; is a modulation target.977
Quant Sizemenu_settingSnaps playback start and stop to musical grid boundaries; None starts and stops immediately.977
Releaseknob0% – 100%Duration of fade-out after note release; uses a logarithmic scale from 0 to 38 seconds; behavior varies by Launch Mode and pad mode; is a modulation target.977
Release Lenmenu_settingAuto-sampler setting: in seconds, how long recording continues after the note length ends, to capture the tail of the note. Distinct from the per-pad ADSR Release. Range 1 to 16.977
Resknob0% – 100%Controls filter resonance — the amount of boost around the filter cutoff frequency; is a modulation target.977
ReverseswitchWhen ON, plays the WAV file in reverse.977
Root Notemenu_settingSets the MIDI note at which the sample plays at its native pitch; one semitone of pitch shift per note away from the root. When None, assumes middle C.977
Sample Everymenu_settingAuto-sampler setting: how many semitones separate each recorded WAV file. Set to 1 to record a WAV per note; set to 12 to record one note per octave. Range 1 to 16.977
Scatterknob0% – 100%Controls how evenly grains are distributed over time; only effective when Density is below 50%.977
Sliceknob≥1Selects which numbered slice plays when a note is triggered; is a modulation target.977
Slice Seqmenu_settingAdvances slice selection on each trigger; options are None, Forward, Backwards, Random, and Stagger; is a modulation target.977
Speedknob0% – 200%Controls the rate at which grains advance through the WAV file; 100% is normal speed, 50% is half speed, 200% is double speed; is a modulation target.977
Startknob≥0sampleSets the sample number where forward playback begins (or reverse playback ends); is a modulation target.977
Sustainknob0% – 100%Sets the volume level the sound maintains while a note is held; not a modulation target.977
Syncmenu_settingPrevents tempo drift by realigning playback to the clock at the specified musical increment while the clip is playing; available only when Quant Size is set.977
Thresholdmenu_settingWhen threshold recording is enabled (Rec Thresh = On), sets the minimum input sound level required to trigger recording to begin. Range -96.00 dB to +0.00 dB.977
Vel Layersmenu_settingAuto-sampler setting: how many velocity layers are captured per note — a separate WAV file can be recorded for each velocity level. Range 1 to 16.977
Widthmenu_settingOn the Delay FX, sets the width of the range of frequencies included when the delay Filter is on.977
Windowknob0% – 100%Sets the spread of the region around the playback position from which grains are selected; 0% always uses the same position, 100% spans about a few seconds.977
