It has MIDI input, an arpeggiator and a six track sequencer. Invest in a controller, hook it up to the Six-Trak for hands-on control as shown in the video below, and reap the benefits. Sequential Circuits Six-Trak for sale: The Sequential Circuits Six-Trak is a polyphonic analog synthesizer manufactured in San Jose USA in 1984. Like the Korg Poly800 earlier in our list, the Six-Trak is hampered somewhat by the mid-80s cost-cutting measure of a button-and-slider editing system, but it’s got a pretty good MIDI spec for its era (perhaps unsurprisingly, since its designer Dave Smith was one of the inventors of the MIDI protocol) and most of the parameters can be edited remotely using CC messages. If the Six-Trak had a knob-laden programming interface it would be a lot more convenient, but it would also be a lot more expensive. That means its sound isn’t the same as other SCI polysynths such the Prophet-5 or Prophet-600, but it’ll cost you less than half the price of a Prophet-600. The Six-Trak also has interesting multitimbral features, allowing each of the six voices to be programmed and sequenced independently, or an interesting unison mode with the ability to layer different sounds from each of the voices. It’s an impressive analogue polysynth for a relatively low price.


This seems a little odd, since the Six Track and the Max both have this feature, but possibly SCI at the time didnt feel it would get much use, or maybe they just didnt have room in. The Six-Trak, like its sister synths the Max and the MultiTrak, uses the Curtis CEM3394 ‘voice-on-a-chip’. Background: Last year it was brought to my attention that the Multi-Trak didnt support CC parameter changes over MIDI. The one to go for, in our opinion, is the Six-Trak, a synth that Gui Boratto recently praised in our studio tour feature. All of which means that the budget SCI synths of that era are slightly overlooked.
