Simple Divisi is a MIDI FX plugin and standalone app that automatically routes incoming MIDI notes across up to 6 independent output channels for real-time orchestral divisi writing.

Features:

• True legato engine with configurable grace window and leg overlap.
• Chord wait buffer (configurable 1–200ms) for accurate chord distribution.
• Base split key — separates top voices (Ch 1–4) from bass voices (Ch 5–6).
• Low part mode: Divisi (2-voice bass) or Octaver (bass + octave below).
• Per-channel octave transpose: −4 to +4 octaves per channel independently.
• 17 factory presets covering orchestral, choir, legato solo, and live performance.
• MIDI capture and drag-to-DAW export (6-track MIDI file).
• Dark and light theme, scalable UI (75% to 150%).
• Piano visualizer shows all 6 channels with color-coded highlights in real time.

Available as AU, VST3, and standalone for macOS 10.15+ and Windows 10 64-bit+.

Designed for composers writing string sections, choir, and divided ensemble parts in real time.
