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.

Thanks
My old 6-trak can be seen used here: http://www.youtube.com/watch?v=s8rwJNvselg
there is a very simple way to enjoy the six trak...
you a have to use an external midi controller as peavey 1600 X or an another one and that's it you can access to all the parameters in direct, live etc....
select your midi channel Rec 3 and then REC 2 and add 2 at each parameters n° on your midi controller.... when your recording the midi parameters are recorded etc....ENJOY
I have two six track...
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.
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.
