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.

I love this synth, but damn it's so early MIDI it [beep] s :(
Somehow it hangs on notes and goes nuts when I sequence it with my Monomachine (MIDI sync data messing things up?)
It works fine with my MPC though..

Does anybody know if the newer/last OS chip fixes this?

A great board- you wont be dissapointed - great for 70s/80s tangerine dream and moroder stuff especially.
I always wonder if the bafoons who claim that they bought some analog collectible from a thrift store for like $30 are totally lying- I tend to think so.

I bought my six trak on ebay. In mono with external chorus and delay, the sound is INCREDIBLE. Very easy to use . I use it in multitimbral mode, 6 monofonics tracks on the sequencer, and in this mode, when the songs is run the 6 recorded tracks, you can edit one patch and tweak the knob (parameter 19) and all the tracks change the cutoff all together, creating a very cool effect. Or if you want you can use CC to change any patch parameter via sequencer. Now I want to do it the six outputs mod and then I will be happy (again).
