i want to count how much "different" midi notes are held down. By "different" i mean ignore the octaves. So if i hold C1 and C2, my count should be 1, not 2.

Putting %12 before a borax is not ok, because if i hold C1, then press C2, then release C1, my count will be 0 instead of 1.

A smart combination of stripnote and borax should do the trick, but for some reason i cannot find a solution.

Calculate the mod of the number [% 12] to fold all values into a single octave then just increment or decrement an index in a [table] or other array as you detect notes being played or released using stripnote

Thanks, i'm not used to deal with [table] but will investigate in this direction !

Here's a pitch-class accumulator to get you started.

Thank you for the examples.
It gives me good hints !


A variation of Stephane's idea with smaller number of objects:

Nice one AK. Love when others strip down ideas !

Count the number of different notes down
