Open source and open hardware eurorack step sequencer with 8 tracks, 16 sequences per track, up to 64 steps per sequence, multiple track modes (Note, Curve, MIDI/CV), routing system, Novation Launchpad support, and a flexible clock system.928

Capabilities 4

CV Sequencer (Chain)cv-sequencer: Curve track mode generates smooth CV modulation signals using per-step curve shapes with configurable min/max voltage range.928
Gate Sequencergate-sequencer: 928
MIDI to CVmidi-to-cv: MIDI/CV track mode converts MIDI note input from MIDI or USB into CV/gate outputs, supporting up to 8 voices with optional arpeggiator.928
Step Sequencerstep-sequencer: 8 independent tracks each with 16 sequences of up to 64 steps; each track can run with different time division, run mode, and scale.928
