Six-Trak
The Six-Trak was an analogue synthesizer manufactured by Sequential Circuits in San Jose, California and released in January 1984, notable for being one of the first multi-timbral synthesizers. It is a six-voice polyphonic synthesizer with one oscillator-per-voice equipped with MIDI, arpeggiator and an on-board six-channel digital sequencer which allows individual or grouped track recording. It was designed as an inexpensive and easily portable 'scratch-pad' machine for trying out arrangements. The synthesizer has both a polyphonic and a unison mode.
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 for the 2012 soundtrack to Australian feature film "Sororal".
The synthesizer used CEM3394, a complete monophonic analog synth chip manufactured by Curtis Electromusic Specialties, which was used in other synthesizers made by Sequential Circuits such as the Multi-Trak, Max and Split-8. The Six-Trak contained 6 chips for 6 voices of different timbre program.
