Description: slice turns any audio file into a MIDI-playable instrument.
Load a sample, set your region, detect hitpoints, and commit your slices. Each slice maps chromatically from C1 upward, ready to play from any MIDI controller or your DAW's piano roll.
CORE FEATURES:
Automatic hitpoint detection with adjustable threshold and sensitivity.
Manual green and red locators for precise region selection.
Destructive trim to isolate exactly the audio you need.
Zero-crossing snap eliminates clicks at slice boundaries.
Stackable per-slice fade-in and fade-out for precise pop removal.
Loop playback that respects your start and end markers.
Real-time waveform display with slice overlay and playhead tracking.
AUv3 PLUGIN
Runs as an Audio Unit instrument inside any compatible host.
Full state save and restore — your slices survive project close and reopen.
Freeze and unfreeze support for offline rendering in Cubasis.
MIDI note triggering with polyphonic voice allocation.
Visual slice feedback on incoming MIDI notes.
STANDALONE APP

What's New in v4.0
Sidechain Recording (AU):
Record audio directly from a host DAW track — insert slice as an effect on an audio track, tap Rec, and capture the audio for slicing.
Works in AUM and Cubasis (audio track insert).
Live input metering during sidechain recording.
MIDI-triggered recording: CC#116 or Note C0 to start/stop hands-free.
Dual AU Registration:
slice now appears as both an instrument (MIDI tracks) and a music effect (audio tracks) in host DAWs
Full functionality in both modes
Real-Time FX in AU:
New FX tab with High-Pass Filter, Low-Pass Filter, and Compressor.
All FX process in real-time through the AU render block.
XY pad visualisation with interactive touch control.
Compressor transfer curve with live attack/release envelope overlay.
FX presets for quick setup.
EQ in AU:

Biquad cascade processing — all 7 filter types (peaking, HP, LP, shelf, notch, bandpass).

Transient Detection Improvements:
Transient hitpoints now snap to zero crossings, eliminating ~11ms offset

Consistent detection between standalone and AU versions
Bug Fixes & Improvements:
Fixed slice 1 not responding to tap when start marker was at position 0.
