The Six-Trak is Sequential's beginner synth. The oscillator chips were apparently built expressly for arcade games, and it sounds like it! It has typical Sequential sounds in an analog six oscillator, six-voice synth. It is not the most fun to program, there is only one knob and you need to assign the parameter you wish to adjust to this knob… however, the assignment settings for the various parameters are listed in the center of the front panel, so it’s not that big a deal. It does however feature MIDI with controllers for its parameters to make editing easier using a computer program such as Unisyn or other external MIDI controller.
The Six-Trak features two operational modes: Polyphonic Mode and Unison Mode. In Unison mode, with all six oscillators, this baby gets fat, rich, creamy and wild making it an excellent stand-in for Moog-like sounds. Also, the Six-Trak is capable of interesting and complex sound effects, mostly thanks to useful cross-modulation and the six oscillators. It also includes a simple 6-channel on-board sequencer. The Six-Trak can be fun and cool! It is used by Überzone and Cirrus.
