Sequential Circuits Six-Trak

“Sequential Circuits Six-Trak Analogue Synth -Works,but has issues.Synth is in very good condition.It has only been outside my studio twice(I moved)since the 80’s.It has the new OS ver 14.Let you just turn the Program knob to change patches..No more punching numbers.Plus a bunch of other cool MIDI stuff.I will also include the original ver 11 chip too. The unit plays great! You can program patches and save them.The only problems I see are if you use the arpeggiator the notes will play a note lower!??Sequencer will record,but also play a note lower on playback..And the stack a/b won’t do anything.I have 2 of these keyboards.I bought them at the same time in the 80’s.Never changed the batteries(40yrs)!They both are doing the same thing..So maybe the battery has something to do with it.Batteries on Amazon are like $25.Not saying that would fix it,but strange they both are doing the same thing at around the same time.Other than that,it works great. Its in really great shape also!Check out the pictures,Most of the original sounds are still in there.Including some great stacked bass sounds. I bought caps for the knobs that give it a Prophet 5 look.They look very cool in the light..You can take them off,not glued.Unit sounds great…It just needs some effects…They didn’t give you that stuff in the 80’s LOL .Thank you for looking!!!” Click here to visit listing on eBay
