“For sale is a Sequential Circuits Six-Trak Polyphonic Analogue Synthesizer. It has 48 keys and is multitimbral, meaning it is capable of playing more than one sound simultaneously and capable of combining up to six sounds, creating complex sonic textures. The rear panel has a monophonic audio output, control footswitch jack, and midi in & midi out jacks. There are user manuals available online to explain the many functions. I am not exactly sure of the production year of this synth, but I believe it was made in the 80’s. In either case, the serial number is shown on one of the photos, so you can look it up online. The battery in this synth has long died. Therefore, I can verify some of the functions but not all and that is the reason I am selling it as is for parts. That said, I plugged it in and powered it up. There is a default sound, so I can verify that all 48 keys work. No broken keys. All Leds light up. You just cannot select any sounds until a new battery is installed and the original sounds are loaded back to the internal memory. The pitch wheel and modulation wheel work perfectly. The master tune and master volume knobs work perfectly. The audio output jack also works perfectly. There is a missing knob for the track volume. Other than that, the front panel looks clean. The right wood panel has a broken corner. A new battery could have this working like new again.” Click here to visit listing on eBay
