Visualize
MIDI notes become particles and beams of light, drawn as constellations while you play. Beautiful on a big screen.
Medussa
See the music you play.
A real-time MIDI visualizer, recorder and editor for the Mac. Practice, capture your performance, quantize it, shape it — and hear it through Medussa’s own sample instrument.
Everything between playing and the final MIDI
One app for the whole loop: see it, practice it, record it, edit it, hear it, export it.
Practice
Load a MIDI file and play along. Loop it until it sits right under your fingers.
Record
Capture your live MIDI performance with metronome and count-in. Zero lag, every nuance kept.
Edit
A full piano-roll: notes, velocity, sustain and CC, tempo and meter — with musical quantization.
Built-in instrument
A sample instrument with zone mapping, round-robins and velocity layers — plus System Piano, plugin or silent sources.
Export
Take the result with you: clean MIDI, ready for your DAW or the next session.
On screen
Dark, quiet interface. The music is the bright part.
The editor
A piano-roll that respects your take
Everything you recorded is right there to shape: move and trim notes, draw velocity, ride sustain and CC curves, change tempo and meter. Quantize when the grid should win — and only then.
- Notes, velocity, sustain and CC lanes
- Tempo and meter editing
- Musical quantization, applied on your terms
The instrument
Sound, without leaving the app
Medussa ships with its own sample instrument: zones mapped across the keyboard, multiple round-robins and velocity layers, and a studio effects chain to sit it in the room.
- 4-band EQ with analyzer, Tape saturation, Delay
- Reverb: Hall, Room and Plate
- Sources: Medussa Sample Instrument, System Piano, Plugin or Silent
