Sequential Circuits Six Track Synthesizer
The Six-Trak was an analogue synthesizer manufactured by Sequential Circuits in San Jose, Californiaand released in January 1984. It is notable for being one of the first multi-timbral synthesizers, equipped with MIDI and an on-board six-track digital sequencer, hence the name. It was designed as an inexpensive and easily portable 'scratch-pad' machine for trying out arrangements. You can latch the arpeggiator and play along with sequences in real time. Also available is a unison mode which renders the keyboard monophonic but allows for very rich sounding timbres.
The Six-Trak is prominently featured and can be heard on the 1998 minimalist space music CD release The Dream Garden, by musician/composer Dane Rochelle. More recently it has been used by composer Christopher de Groot for the 2012 soundtrack to Australian feature film "Sororal".
