If you are seeing this listing. Then you already know what a legendary and great sounding synth the Six-track is. 6 Discrete analogue voices, that can be independently sequenced within the internal sequencer, all utilizing deferent preset and settings. I've spend my own money to have it professionally cleaned out and restore so that every button, knob, and wheel works. Nevertheless, it still is an instrument from the 80s, so signs of use and age are present. Look a pictures for reference.
