Chord chaining
Every chord follows from the last: motion by fourths and fifths, cadences resolving to the tonic. GRAVITY sets how strongly it resolves.

⚠️ MIDI plugin: it produces no sound of its own. These demos let you hear the sequencer driving a synthesiser, what the plugin makes PLAY, not how it sounds.
UNDER THE HOOD
Every chord follows from the last: motion by fourths and fifths, cadences resolving to the tonic. GRAVITY sets how strongly it resolves.
Chords, bass, floating notes and orbit notes, each with its own clock, its own octave from −3 to +3 and its own chance of playing.
From diatonic modes to Japanese and exotic scales, with a selectable root and four moods: Calm, Deep, Bright and Strange.
Records 1 to 64 bars of the output, aligned to the host bar grid, then plays it back as a loop. Eight favourite slots saved with the project.
ALTERN keeps the recorded rhythm and regenerates the notes on every pass, dialled from 0 to 100 % to let the loop drift without a jump.
Twenty starting points embedded in the plugin, alongside your own user presets.
CHORALIS makes no sound of its own: it generates a MIDI stream, chords, bass, notes, orbit, for the instrument of your choice. Four voices run on independent clocks and keep evolving according to your settings.
Eighteen controls across three sections, HARMONY, GENERATION, ARTICULATION, shape the harmony, the density and the way notes breathe. Tempo always follows the host, with a /8 to x8 clock multiplier, a global SWING and BAR LOCK to pin events to the grid.
The engine picks each root from the one before it. MOOD colours the motion: firm cadences, the minor side, a push to the dominant or unexpected turns.
Each voice moves at its own pace. Enable, transpose or thin them out separately without ever freezing the shared harmony.
The looper freezes a passage; ALTERN keeps its rhythm and regenerates its notes, as gently as you like.
Drag the loop straight onto a MIDI track in your DAW, or store it in one of the eight favourite slots.
