Midicycles: visualizing MIDI in polar space
midicycles is a small tool written in Go that visualizes incoming MIDI notes. It was originally created to both hear and visualize output from Melrōse programs, but it also works with any MIDI source. The project is simple to start and flexible to tune. On startup it opens one or more MIDI input ports and renders note activity in near-real time. How it renders Most MIDI events represent a Note-ON or Note-OFF moment at which a Muscial Note (by number) is started or stopped.
