Triadex The Muse

   (0 reviews)

The Triadex Inc. The Muse is a sequencer-based synthesizer, produced in 1972. It is an algorithmic, deterministic event generator, utilizing early digital integrated circuits to generate an audio output that can sound very musical. It produces a sequence of notes based on the settings of about a dozen different parameters, including four small sliders that control Volume, Tempo, Pitch, and Fine Pitch.

Since the Muse was designed as a composition tool, not a synthesizer, there is no control over the timbre of the sound; rather, the front panel controls affect the melodies that are generated. The exact logic behind the composition engine is rather technical, and not exactly intuitive.

The four small sliders in the lower-left control Volume, Tempo, Pitch, and Fine Pitch. The switches to either side are used to start and stop the sequence or to step through it note-by-note.

Of the eight larger sliders on the right, four control the musical intervals used (labeled A, B, C, and D), and four control the theme (labeled W, X, Y, and Z). A rest can be substituted for the lowest note by flipping a toggle switch.

The tempo clock can be slaved to that of another Muse, allowing for multi-part compositions. The Muse even had an even rarer accessory option called the "Light Show", which flashed colored lights in time to the music.
