What saadet does
- Saadet makes the FM-1 one polyphonic synthesizer with four engines: P5, FM6, CZ-1 and J106.
- The ALGORITHM knob moves between engines and the screen takes on each engine's colour.
- The PRESETS knob browses the current engine's sounds, loading one when the knob rests.
- Perform with the arpeggiator, HOLD, chords, strum, scales and microtonal tuning.
- REC latches the notes you let go of until you play the next chord.
- Store sounds in 384 shared user slots with favourites, and the current sound returns at power-on.
- A browser editor mirrors the panel and backs up all sounds, favourites and settings.
- Connect over USB MIDI, TRS MIDI input and Bluetooth MIDI, with stereo USB audio playback and capture.
