The same code the FM-1 runs, with sound. Play it with the mouse, a touch screen or the keyboard.
The FM-1
Turn your phone sideways for bigger controls.
Tab moves through the knobs, the buttons, the black keys and the white keys. Arrow keys turn a knob, Page Up and Page Down faster. Space or Enter holds a button or key down while you hold it; Shift and Enter keeps it down until you press it again (with a mouse: Shift-click or right-click).
The break plays at 170 BPM. The white keys are its sixteen slices: press one and it lands on the next snap point; hold it and it loops.
The black keys are momentary effects: rolls, reverse, freeze, half speed, tape stop, gate, random, filter, dub. Hold one and turn K1–K4 to tune it.
Each button opens a page; press it again for its next part. SEL held a second lists every combination. All of it is in the control map.
