Sequential Circuits Six-Trak

The Six-Trak is Sequential's beginner synth. It has typical Sequential sounds in an analog six oscillator, six voice synth. It is not fun to program, there is only one knob and you need to assign the parameter you wish to adjust to this knob. The assignment settings for the various parameters are listed in the center of the front panel. It does however feature MIDI with controllers for its parameters to make editing easier using a computer program such as Unisyn or other external MIDI controller.

The Six-Trak features two operational modes: Polyphonic Mode and Unison Mode. In Unison mode, with all six oscillators, this baby gets fat, rich, creamy and wild making it an excellent stand-in for Moog-like sounds. Also, the Six-Trak is capable of interesting and complex sound effects, mostly thanks to useful cross modulation and the six oscillators. It also includes a simple 6-channel on-board sequencer (of little usefulness these days). Its biggest limitations were: shortest attack too slow for really percussive sounds, smallest vco frequency adjustment too big for Zawinul-style subtle frequency envelopes & LFO, and the lack of built-in chorus, which would have helped to thicken the rather thin sounds in Polyphonic mode. The SixTrak can be fun and cool but is overshadowed by its cousin - the Multi-Trak. It is used by Überzone and Cirrus.

One of my favorite synths of all time. Had it for almost 20 years and still going strong.

Another quirk with the Six-Trak is that the pitch wheel wasn't very well calibrated so in the unison mode the voices would go all chorusy sounding when you bend them. I also seem to remember a mode where you could assign different patches to each of the six oscillators for an even bigger mon sound.
