OSS DEMO

Everything runs locally on your device and nothing is sent anywhere. This is an open-source demo, not a service.

Starting
The sequencer runs inside the audio thread

Nothing is uploaded and nothing is pre-rendered. The engine holds the pattern and the transport, so a turn of CUTOFF, RESONANCE or ENV MOD reaches the note already sounding.
