Although typically understood as a slimmed down entry level offering from Sequential Circuits, the Six-Trak has the distinction of being one of the first multi-timbral MIDI synthesizers. Like the name says, the built in sequencer can access all six voices individually for easy stand alone composition. This Six-Trak is in good cosmetic shape with average wear and tear, no sonic issues. All voices, keys, buttons, and pots in good repair. Includes original box!
