What bass-something-2 does
- You play a monosynth with two oscillators, a sub and noise, through a Classic or Acid filter with drive.
- The arpeggiator plays held notes in six modes over up to four octaves across 32 rhythms, with swing and latch.
- A 32-step sequencer keeps four sequences with rests and legato, timed by the arp's rhythm and transposed from the keys.
- Press REC for a random sound, or hold REC and press OCT+ for AFX mode, where every key plays differently.
- The keys answer to velocity and pressure, and SAVE stores the sound into one of 32 patches.
- Bass Station II patch dumps and whole banks load and send over USB, so an editor can store your sounds.
- MIDI arrives over USB, Bluetooth and TRS, and the USB cable also makes the FM-1 a sound card.
Its modes
- OSC FILTER
- Set oscillator 2's tuning, the filter type, oscillator 1's wave, cutoff, resonance, drive and fine tune.
- OSC MIX
- Set oscillator sync, oscillator 2's wave, glide, ring modulation, noise and both pulse widths.
- OSC TUNE
- Tune oscillator 1 coarse and fine, set filter key tracking and the mod envelope's pulse width depths.
- MOD ENV
- Set the mod envelope's attack, decay, sustain and release and its depths on pitch and cutoff.
- AMP ENV
- Set the volume envelope and how velocity affects loudness and the mod envelope's depths.
- LFO 1
- Pick the LFO's destination, wave, rate and amount.
- ARP
- Switch the arpeggiator on and choose its mode, retrigger, latch, octaves, swing, tempo and rhythm.
- SEQ
- Record and edit the four 32-step sequences, step by step, with notes, rests, legato and gate.
- PATCH
- Pick a patch, save the sound into it, and send it out as a SysEx dump.
