Controls and shortcuts reference

Signal chain bar

Context bar

Time/Pitch notes:

When ALGO=Repitch and STRETCH=ON, PITCH and TUNE become BPM-derived read-only displays.
In SLICE mode, the context row also exposes the selected slice’s NOTE/RANGE mapping.

Slice context row

Control	Function	Notes
`NOTE / RANGE`	Switch between single-note and note-range triggering	Slice-only, shown in the context bar
`NOTE`	Single trigger note	Shown only in note mode; drag to edit
`LOW`	Lowest note in the trigger range	Shown only in range mode
`HIGH`	Highest note in the trigger range	Shown only in range mode
`ROOT`	Transposition and filter key-track reference note for the slice	Shown only in range mode
Note name text	Read-only pitch name display	Appears after the numeric field(s) and is not draggable

Control	Function	Notes
`ON`	Enable/disable the filter	Per-voice filter toggle
`TYPE`	Filter mode	`LP`, `HP`, `BP`, `NT`
`SLOPE`	Filter steepness	`12 dB` or `24 dB`
`CUT`	Base cutoff frequency	`20 Hz – 20 kHz`, log-skewed at 1 kHz
`RESO`	Resonance amount	`0–100%`. Higher values emphasize the cutoff region
`DRIVE`	Pre-filter saturation	`0–100 dB`. Adds harmonics before filtering
`ASYM`	Drive asymmetry	`0–100%`. Biases waveshaper toward even harmonics for a warmer tone
`KEY`	Key tracking amount	`0–100%`, relative to the slice/root note mapping
`ATK / DEC / SUS / REL`	Filter envelope shape	A/D/R `0–10000 ms`, S `0–100%`. Separate from the amp envelope
`AMT`	Filter envelope depth	`−96 to +96 st`. Bipolar semitone offset applied to cutoff

Filter notes:

Start with ON, TYPE=LP, modest RESO, and a lower CUT to hear the filter clearly.
Raise DRIVE if you want a dirtier or more aggressive tone before the filter stage. Add ASYM to bias the saturation toward even harmonics for a warmer, tube-like character.
Use KEY when you want higher MIDI notes to sound brighter and lower notes darker. In slice range mode, the filter tracks from that slice’s ROOT note.
Use positive AMT for a classic opening filter envelope and negative AMT for an inverted sweep.
AMT is in semitones because it controls octave-style movement of cutoff. +12 st doubles the cutoff, -12 st halves it.
Filter settings resolve at note-on, so changing cutoff while a note is already playing affects the next note rather than re-tuning the current voice.

Amp module

Control	Function	Notes
`ATK / DEC / SUS / REL`	Amp envelope	ATK `0–1000 ms`, DEC/REL `0–5000 ms`, SUS `0–100%`
`TAIL`	Release-tail toggle	Allows playback to continue past slice boundary during release
`GAIN`	Output gain	`−100` to `+24 dB`

Playback module

Control	Function	Notes
`REV`	Reverse playback	Toggle
`LOOP`	Loop mode	`OFF`, `LOOP`, `PP`
`FADE`	Loop crossfade amount	Active when `LOOP` is `LOOP` or `PP`
`MUTE`	Mute group	`0–32`, `0` = off. Voices in the same group choke each other
`1SHOT`	One-shot playback	Ignores note-off until the slice ends
`OUT`	Output bus	`SLICE` mode only, `1` to `16`
`VOICES`	Max playable voices	`GLOBAL` mode only, `1` to `31` (voice 32 is reserved for the preview voice)

Master and global controls

These live outside the four signal-chain modules but are exposed as APVTS parameters for DAW automation. See the Parameter reference for the full list.

Parameter	Function	Range / values
`masterVolume`	Master output gain	`−100` to `+24 dB`
`maxVoices`	Active voice limit (same as `VOICES` above)	`1` to `31`
`uiScale`	Editor scaling factor	`0.5` to `3.0`, step `0.25`. Edit via SET → Scale Up / Scale Down.

Action bar

Button	Function
`ADD`	Toggle draw-slice mode (shows a waveform hint to drag and create a slice)
`LAZY` / `STOP`	Start/stop real-time lazy chopping
`AUTO`	Open Auto Chop panel for the selected slice (prompts you to select a slice first if none is selected)
`COPY`	Duplicate selected slice
`DEL`	Delete the selected slice, or the selected sample when the sample lane was the last thing clicked
`ZX`	Snap edits to nearest zero crossing
`FM`	Follow MIDI (auto-select played slice)
`RESEQ`	Resequence MIDI note assignments (opens overlay with `BY POSITION` or `AS CREATED`)

Auto chop panel

Requires a selected slice before opening.

All three parameter cells support drag-to-edit (drag up/down) and double-click text entry.

Control	Function
`SENS`	Transient detection threshold (`0–100%`) with live marker preview
`MIN`	Minimum slice length (`20–500 ms`) — suppresses transients too close together
`SPLIT TRANSIENTS`	Split selected slice at detected transients
`DIV`	Equal split count (`2–128`)
`SPLIT EQUAL`	Split selected slice into equal divisions
`CANCEL`	Close panel without applying
