Vocal Chop Sequencer · macOS AU / VST3

Chop a vocal into a groove.

A host-synced, zero-latency 16-step gate sequencer that slices a sustained vocal, loop, or pad into a bouncing tech-house rhythm — from a tight 16th-note pulse to full glitch mangle.

The signature

16 steps, four slice modes, one groove.

Draw the pattern on a 16-step grid with per-step on/off, level, and slice mode. Each step renders click-free as Gate, Reverse, Tape-Stop, or Stutter — synced to host tempo with sample-accurate MPC-style swing.

Gate · Reverse · Tape-Stop · Stutter.
Under the hood

A rhythm engine built for chopping vocals.

Per-step slicing, swing, stereo motion, and a parallel wash — all locked to host tempo.

Gate sequencer

  • 16 steps with per-step on/off and level on a draggable grid
  • Gate / Reverse / Tape-Stop / Stutter render mode per step, click-free
  • Moving playhead and sample-accurate MPC-style swing (0–100%)

Per-step motion

  • Attack / Hold / Decay envelope with Staccato, Ramp-Up, and Sidechain-Pump shapes
  • Automatic panning for bouncing per-step stereo placement
  • Dimension micro-pitch widener with Width + Micro-Tune, mono-safe below 300 Hz

Wash & timing

  • Auto-ducking parallel reverb + delay that blooms in the gaps
  • MIDI retrigger snaps the sequence to step 0 while a note is held
  • Free-run clock keeps grooving when the transport is stopped

Workflow

  • Delta Monitor — hear only the rhythm Chopix removed
  • A/B compare two parameter states
  • One-click randomize for new patterns
  • Preset save / load
