'We’re pleased to introduce FM1 Open, M-VAVE’s firmware and development project for FM-1 users and developers. It combines multiple synthesis engines, sample playback, and an eight-track step sequencer. Independent tracks let you arrange melodies, bass, drums, and custom samples, edit their sounds and rhythms, and create looping patterns.'
