Free Virtual Instrument Recreates Sequential Circuits Six-Trak

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

The developer says that Six-Traq offers a close emulation of the original, but expands on it with up to 96-voice polyphony, micro-tuning and other modern features.


  • Close simulation of the original hardware
  • Extended Poly/Multi modes, up to 96 voices polyphony
  • 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
  • Supports MTS-ESP by ODDSound dynamic micro-tuning
  • Resizable user interface (not “N” version!)
  • MIDI Learn – all parameters can be controlled by MIDI CC
  • Plug-in supports Windows and macOS

Six-Traq is available now as a free download.

  1. As always a one-to-one comparison would be great. Yes it’s free which is awesome but I remember doing a comparison of their DW-8000 emulation with an actual EX-8000 I owned at the time (which I was selling so I wasn’t even biased by that fact) and found they didn’t get the filter right and the software just didn’t sound half as good as the hardware. Hopefully they got this one better (always wanted a 6-track so I’m very excited about that one !).

    1. Very, very few virtual analogs get the filter right. It’s always worth running FB synths at 96kHz as they don’t have oversampling. Makes the world of difference.

      The Crumar Bit One emulation is pretty close to the original.

  2. Nicely done. I don’t normally go for single-oscillator synths, but stacking a couple of these can lead to a solid Sequential voice. If you already have some form of Prophet, this is good icing the same way an SEM fits neatly above an OB.

      1. Seems this is what most people care about. I’m not sure what the reason is, I guess nostalgia means everything old was better, and if you want to be successful like your favourite artist, you must have the exact same tool. It’s always fun to see how they lose their confidence in a blind test.

  3. Buffaloketchup: I hear you, especially about the filter. I once played a pair of DW8000s, so I’m familiar with it. I’ve heard those waves in pretty much everything Korg since then.

    Most softsynths I’ve been able to contrast with vintage hardware I once owned hold up really well. The TAL-pha will even read the original JUNO-1/2 patches. I won’t complain when I get 95% of the original, including modern goods like effects. Current FX chains can make a home organ sound like a Fairlight.
