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.

[1] It was designed as an inexpensive and easily portable 'scratch-pad' machine for trying out arrangements.

[2] 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".

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.
