Pie Plate - MIDI Chord Splitter

Pie Plate is a MIDI voice router and chord splitter for Ableton Live.

The GUI has lots of options, but it "just works" out of the box how you want.

Drop it on a MIDI track, drop a satellite device on each of your synth tracks, and play chords.

Each note in the chord lands on a different voice, synth, or track.

What makes Pie Plate different from free MIDI splitters is stable, chord-aware voice assignment. Free splitters route notes by arrival order, so the same chord shape can end up scattered across different synths every time you play it.

Pie Plate locks the assignment by pitch instead: the lowest note of the chord always goes to Synth 1, the middle note to Synth 2, the highest note to Synth 3, and so on. Same chord, same routing, every time.

15 routing modes:

• Simple Poly: first free voice, steals oldest if full.
• Poly Shape Stable: sorted by pitch, fully stable across releases.
• Stack All: every voice plays the same note, unison-style.
• Chord Position: positional voicing with optional play-order sorting.
• Round Robin: forward, ping-pong, and reverse.
• Key/Velocity Zones.
• Pure Random.
• No Repeat Random.
• Low Bias Random.
• High Bias Random.
• Chord Memory: capture a chord and trigger it from any single key.
• Minimal Movement: smooth voice leading for sustained pads.
• Legato Duophonic: lowest = bass, highest = lead.

What you can do with it:

• Turn a rack of monosynths into a real polysynth.
• Build evolving pads where each voice has its own modulation personality.
• Stack up to 16 soft synths so every note in a chord comes from a different instrument.
• Create bass and lead duophonic splits with musical retrigger behavior.
• Use one-finger chord memory for fast performance and writing.

Up to 16 voices, each routed to its own track. Includes count-safe release tracking, a configurable settle window for cleaner chord attacks, and panic/mode-switch safety so changing modes mid-performance doesn't leave hung notes.

Requires Ableton Live 11 or 12 with Max for Live.

Works on Windows and macOS. Includes the main router device, 16 satellite voice devices, and full PDF documentation: Quick Start Guide and Reference Manual.
