Stellarizer is a performance-driven MIDI sequencer built to turn notes into evolving, editable, export-ready musical ideas.
Capture a phrase, import a MIDI clip, build one step at a time, draw notes directly, or generate a new source. Then shape timing, contour, rhythm, density, articulation, structure, velocity, duration, melody, and harmony while keeping the musical identity of the original idea intact.
Stellarizer generates MIDI rather than sound, so it can drive your favorite software instrument, sampler, drum machine, or external hardware. It is equally at home evolving a bass line, reshaping a lead, breaking apart a chord progression, building generative patterns, or helping you escape a creative rut.
Again, what Chris has designed I can’t understand technically. But it is a fascinating way to take a MIDI file and produce interesting patterns and sequences.
