"14 trillion musical note combinations

It has been claimed that the Triadex Muse was the first digital device for making music. The original Muse was designed by Edward Fredkin, now at Carnegie-Mellon; and Marvin Minsky ( http://web.media.mit.edu/~minsky/ ), now at the M.I.T. Media Lab; in the late 1960's.

The Muse is a music composer machine or digital
synthesizer and melody composer, involving early
logic modules in a unique circuit that allows the
possibility of 14 trillion musical note combinations.

Manufacturer: Triadex Inc., Brookline, Massachusetts
Inventors: Edward Fredkin and Marvin Minsky
Original Price: $249

The Muse is an algorithmic music generator: it uses digital logic circuits to produce a sequence of notes based on the settings of various parameters. 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 exact logic behind the composition engine is rather technical, and not exactly intuitive. The tempo clock can be slaved to that of another Muse, allowing for multi-part compositions.

Their patent abstract of this electronic music composer reads as follows:

In the apparatus disclosed herein, a note generator is controlled by a long term, quasi-periodic function which is in turn generated by applying digital feedback in preselected combinations around a digital register. The register comprises means for holding a plurality of bits of digital information in a given order, e.g. a shift register or counter, the held information being changeable according to a predetermined pattern in response to input signals applied thereto. Digital feedback is provided by applying to the register at least one input signal which is obtained according to a preselectable or adjustable code from bits of information obtained from various points in the register itself. The apparatus thus, in effect, composes music as distinguished from merely synthesizing sound.

It is not known exactly how many Muses were made, but they are very rare, and were not available in stores."
