Choose an internal foundation or import your own audio sample, hit the orange trigger, then raise Drive and Clip. Use the pitch sweep to make a brighter, harder transient.
For Frenchcore, aim for a long tonal body; for terror, shorten duration and increase the initial pitch.
Audio starts only when you interact with the page, as required by iPhone Safari. Headphone/speaker volume can be extremely high with heavily distorted kicks. Start quietly.
All synthesis, imported audio, and user presets are processed on this device. No internet service or account is required.
