Cozmic Pulse · VST3 and AU arpeggiator
Arpeggios that evolve, when you decide.
This piano roll plays live: a Cm7, A♭maj7, E♭maj7, Gm7 progression at 120 BPM. Turn the sound on, pick a chord or play your own notes.
On your computer keyboard, the middle row plays C D E F G A B C. Hold several keys for a chord.
The evolution engine
Nothing changes unless you allow it. Everything can change if you do.
In Pulse, every parameter starts locked: the arpeggio stays the way you set it. Scroll, and the six rows unlock one after another. The arpeggio at the top of the page changes with them. Clicking a padlock does the same.
Arpeggios that don't go round in circles.
Pulse arpeggiates your chords, fits them to a scale or plays its own chord progression. Its evolution engine moves the rate, octaves, note length, density, velocity and repeats. And it replays exactly the same thing on every playback.

- Evolution engine
Six rows and five behaviours: progressive, cyclic, probabilistic, contextual, triggered.
- Chord grid
Four parts, key changes, voicings and a progression generator.
- Correlations
Link two parameters: when density drops, note length can follow.
- MIDI capture
Drag the generated arpeggio onto a track, or send it to a virtual MIDI port.
