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).

MIDI
The FM-1 makes no sound: Berlinan plays your synths over MIDI, each voice on its own channel. Send its MIDI to an output of this computer (a synth, an interface, or a virtual bus such as the IAC Driver into a DAW), and choose an input for EXT sync (MIDI clock, Start and Stop, as on the FM-1's USB port). Chrome, Edge or Firefox; the browser asks once to allow MIDI.
