Device simulation: Raspberry Pi 5, 7" touchscreen at 1024×600, 4 encoders and 4 buttons wired to the GPIO.
No user preset yet.
Drag vertically or use the mouse wheel. Turned slowly, an encoder makes small steps; turned fast, big steps. With Shift: extra-fine. Double-tap a tile: default value. Keyboard: click an encoder, then ↑ ↓.
Drag on the waveform to place the head. The solid handles at the bottom set W1, the hollow handles at the top set W2. Drag vertically on a tile to change its value.
Play starts and stops. Shift + Play (or the PREVIEW button) plays the original sound from start to end, with no windows or effects. Page goes to the next page (with Shift: previous). Sync toggles tempo sync (with Shift: tap tempo). Shift latches in the simulation. Shortcuts: Space Play, Shift + Space Preview, P Page.
