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 midi implementation is pretty advanced for the time. You can control it with any midi controller that send CC from #1 to #36 see my video about it :

I've made a Six-Track editor using CTRLR, suitable for Windows, Mac 32/64, in VST and AU. It offers MIDI control over all parameters and program changes. I don't know how to implement a patch library so maybe someone else can help with that.

Can anyone help with advice on the following: on every 6th note on my SixTrak in poly mode the sound is louder and discordant. I wonder if a voice chip is faulty? Any thoughts welcome....
Thanks

I bought one of these brand new in 1984. Never used it other than noodling and home recording. It sat in my closet for almost 20 years untouched. I sold it to a musician friend of mine (it was in mint condition) for $200. He toured with it for years. Needless to say, it was no longer mint, it was tornnn up, but it still worked. This keyboard inspired many great songs in their band. I'm glad someone got good use out of it.

hi i'm french
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...
