Full Bucket Music has introduced Six-Traq, a free virtual instrument, based on the Sequential Circuits Six-Trak synthesizer from 1984.

  • Oscillator with three waveforms, additional white noise generator
  • Classic self-resonating four-pole lowpass filter
  • Individual envelopes for oscillator, filter and amplifier
  • Onboard sequencer and arpeggiator
  • SysEx import/export
