This is a Future Retro Zillion algorithmic sequencer. A few settings cause the Zillion to generate sequences of notes via Midi.
It’s based on the Triadex Muse, a musical toy from the 1970’s.
Here’s a Zillion with a bunch of other Eurorack stuff.
The Muse was designed by Marvin Minsky and Edward Fredkin, both MIT professors with an interest in artificial intelligence, Intended as a compositional aid.
Here’s a vid with the Triadex Muse, Amplifier and LIght Show.
An algorithmic music generator, the Muse uses digital logic circuits to produce a sequence of notes based on the settings of various parameters. It has four small sliders that control Volume, Tempo, Pitch, and Fine Pitch.
Extremely rare. I wish I woulda gotten one back in 1972.
