Turn one performance into an entire constellation of ideas.
Stellarizer is a performance-to-pattern MIDI sequencer from S1gns Of L1fe Audio. Play a phrase, capture its timing, contour, velocity, note length, and sustain, then explore musically related patterns without losing the feel of the original performance.
Built for fast musical discovery:
Capture live MIDI performances in Free, synced, fixed-length, or custom-length modes
Generate distinct ideas with the Pattern Playground and Near, Far, and Deep Space discovery ranges
Shape contour, rhythm, density, articulation, structure, timing, octave spread, note length, and musical relationship
Keep results in key with automatic Scale Lock and instantly shift patterns across octaves
Store eight playable pattern slots and switch instantly, on the next beat, or on the next bar
Preserve captures and discoveries in the Recordings atlas
Save and organize presets, then export or drag finished MIDI directly into your DAW
Follow your host's tempo, transport, time signature, and playback position
Stellarizer generates MIDI rather than sound, so you can pair it with any instrument in your setup - from your favorite software synth to external hardware.
Requires a DAW or host capable of routing MIDI generated by plug-ins; setup varies by host.
WHAT'S NEW IN v0.9.1:
Polyphonic sequencing preserves chords and overlapping notes throughout the creative workflow.
Automatic polyphonic MIDI detection recognizes chordal imports and enables the correct mode for the source.
Create Source generates original musical starting points without requiring a performance or imported clip.
Direct note editing lets you add, move, resize, and delete notes inside Stellarizer.
Gravity transforms a running sequence in real time using the notes you play, while Scale Lock keeps the result musically grounded.
A rebuilt randomization engine delivers more surprising, musical variations while respecting the selected quantization grid.
The eight-slot Pattern Playground now produces stronger identities, more meaningful rerolls, and immediate Shape integration.
Scale Lock can remap existing material when you change key or scale.
MIDI import now adapts the sequence length to the source and remembers your most recently used folder.
New factory presets showcase melodic, rhythmic, and polyphonic workflows.
Refined Allowed Notes controls, quantization display, editing behavior, labels, spacing, and visual polish.
