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.

For all you guys that are wondering, Wine Country has stated that for modern MIDI usage, you will need at least an OS 9 or 11 chip (final release, available through WC) with a MIDI filter. To check what OS you have, hold down the Track record button, and then press 5 on the keypad. What OS you have will show up in the display. If nothing appears, then you have less than OS 7.

Regarding the synth in general, it's great!. The ability to store 100 patches, an unquantized polyphonic sequencer, a brilliant stack mode to create some hellish strings on it plus unison mode, I'd give it 5*'s!

Perhaps your sixtrak goes nuts if you send to much cc controllers to the synth.

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?
