Sequential Circuits Six-Trak

Sequential Circuits Six-Trak Image

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.

The primitive arpeggiator is really usuefull in the sense that it's easy to play and to make useful in actual songs, it won't do "crazy" arp-things (as other more advanced arps), that you won't be able to use anyhow. (btw - the arp is up/down AND assigned)
IMO it sounds better than Korg Polysix or Rolands vintage Junos for example. The only con is the lack of knobs, but as I said, that problem can easily be solved with Kiwi Patch Editor or if you wanna setup some MIDI-control solution of your own.
If you'd offer me 2500$ maybe I would consider selling it.

Truly amazing synth! Highly underrated. The 3 star rating is a joke! It's warm, fat, rich and creamy. It really comes alive if you get a Kiwi Patch Editor or similar, to get hands-on knobs to tweak! (if it would have knobs it would be a real classic). But it's simple to program without a "knob-modul" also, but you won't be able to tweak sounds easy in a live situation.
It's by far the most versatile synth i've ever played. GREAT for everything. Unison or stacked for REALLY fat bass/leads. And the polyphony is not "thin" as some claim you can make really creamy pads or really ambient pads.
