What tonic-fm1 does

  • Four tracks share twelve voices, each track running four-operator FM with eight algorithms, virtual analog, or a kit of eight synthesized drums.
  • The sequencer holds up to 64 steps a track with parameter locks, sound locks, trig conditions, micro timing and retrig.
  • Every voice has overdrive, LO-FI, two filters, an insert effect, two LFOs and a modulation envelope.
  • Chorus, delay, reverb, a master compressor, a DJ filter and sidechain ducking shape the whole mix.
  • Hold HOME for mutes, fills, chains, tap tempo, loop rolls, tape stop, filter sweeps and reverb freeze.
  • TONIC saves by itself once the sequencer stops and the sound dies away, keeping 32 patterns, a pool and a library.
  • USB MIDI in and out plus TRS in carry notes, clock and control, and any track can play an external instrument.
