Note Space
A 128-bin distribution over MIDI notes. Counts or weights retain register and repeated occurrences.
Try it
Count concrete MIDI notes
Add notes to a small sample. Repeated notes add weight. A note space keeps 128 MIDI bins; folding it combines octaves into twelve pitch-class bins. Measuring every note from the lowest one gives a rootless point space. Transposition moves the note and pitch-class weights while leaving relative points unchanged.
Click a note to add another occurrence. Up to twelve events can be loaded in the player.
