This video, via AnalogAudio1, takes a look at the vintage Sequential Circuits Six-Trak analog synthesizer:
Synthesizer demo of the analog synthesizer SCI Six-Trak from 1984. It was the first multitimbral MIDI synth on the market (it came before Oberheim Xpander).
In this movie I play some of my own sounds – on some sounds I used a digital delay (Roland DEP-5) and reverb (Lexicon MPX-500). In the intro I used the sequencer of the Six-Trak.
The Six-Trak has 1 VCO per voice (6 voice polyphonic). It also has 3 ADSR, 24 dB VCF, noise generator, LFO with different waveforms. It has a sort of “slimmed down polymodulation”: VCF modulation by VCO for dirty and metallic timbres. Unison mode for fat, monophonic sounds. Great “stack mode” allows layering of six different patches.
I like the Six-Trak very much. I would wish it had multiple outputs and a chorus effect.
The Six-Trak is not on a par with some of Dave Smith’s other classic synths. The Six-Trak has a fairly limited architecture and was designed to be more of an entry-level synth.
Nevertheless, resale prices for the Six-Trak have jumped in the last few years, as interest in analog synths has soared and people discover that the Six-Trak can make some great sounds.
