Chord Performance TheoryFULL LENGTH holds every voice for the complete harmonic slot (with Chord Length = 4, that is 4 beats / one 4/4 bar). NATURAL PLAY gives every voice a different grid-quantized release: common tones sustain, semitone/step resolutions stay connected, unresolved extensions breathe earlier, and large leaps get separation.

Metric anchorsStrong beats prefer chord tones. Tensions live on weaker subdivisions and are given a resolution target.

Controlled non-chord tones9ths/11ths/13ths come from the selected scale; chromatic neighbors appear only when Adventure/Tension justify them, then resolve by semitone.

Odd pitch cycles over 4/45/7/9/11-step note-order cycles create evolving electronic patterns while every MIDI onset stays on your selected grid.

Voice continuityCommon tones are preferred across chord changes and large leaps are penalized; octave displacement is deliberate and bounded.

Euclidean accent layerMaximally-even pulse masks shape accents and gate behavior without destroying harmonic anchors.

Deterministic variationSeeded cycle logic gives repeatable mutation rather than unbounded randomization.

Design references: Ableton Arpeggiator/MIDI Tools (pattern order, synced rate, gate, transposition); Bitwig Arpeggiator + Operators/Note Repeats (octave behavior, cycle/probability logic, Euclidean patterns); Godfried Toussaint’s work on maximally-even Euclidean rhythms.

MPE Character Pitch Bend Range Glide Amount Vibrato Timbre / CC74 Pressure Protect Common Tones Theory-aware Expression

What the MPE engine does: every sounding note receives its own member channel. Pitch uses per-note Pitch Bend, brightness uses CC74, and pressure uses Channel Pressure. Common tones stay calm; leading tones and semitone resolutions may glide toward their destination; unresolved extensions get more timbre movement; top voices are more expressive than bass notes. The exported MIDI includes MPE zone configuration and member-channel pitch-bend sensitivity.
