Composer Stephen Taylor performs Coprime Colours, a microtonal composition, on a Starr Labs Wilson MicroZone U-990 hexagonal-key MIDI instrument.
The Wilson 990 Generalized Keyboard is one of the world’s largest Array or Matrix keyboards. With it’s mongo array of 810 keys, tThe “U-990? (offering 9 ranks of 90 keys) is designed so that a musician may create any variety of tonal systems, fingering systems, and divisions of the octave within the world of MIDI.
This works well with microtonal music where a large array is needed for each octave, or with Western 12-tone music where several independent keyboards can be set up on a single set of hardware. The intent is to allow the user to define any arrangement, or multiple arrangements, of notes and fingerings which seem to be musically applicable to situation at hand.
