What is Sloop Fm1?

SLOOP turns the FM-1 into a four-track groovebox you play live: three synths and a drum machine with 16 sounds on the white keys, twelve synthesis engines, 153 sounds, 37 drum kits, your own samples, a song mode you play with your hands, USB audio, MIDI in on the jack and MIDI clock — and now physical models (guitars, sitar, bells, hand drums), a noise engine, six-operator FM with DX7 patches, parameter locks, micro timing, fills, a quick chain of sections and the sequencer to MIDI out.
