The infinitone is a computer controlled microtonal soprano saxophone. It operates similarly to a slide saxophone in that it can play both a pitch continuum and pitch fluid but it uses a set of stepper motor controlled openings that overlap to allow the full range to be played. The openings are controllable up to 256 notes per octave (256EDO) with a range of 2 octaves (512 tones). the stepper motor allows the openings to slide between these pitches.

Subhraag has also released a microtonal music software ¹⁾
