Midi filtering into pitch classes

April 4, 2007 | 3:00 pm

Hello everyone….

I’m trying to build a patch to filter each pitch class from a midi file, in real time, into 12 streams (ie all the Cs, Csharps, D’s etc. whichever octave) so that each pitch class can be treated differently.

I’m pretty familiar with max, or at least the audio and maths side, it’s just dealing with multi-voice midi files that has me stumped. If it was mono I guess I could just use seq, midiparse and %12….but how do i start dealing with more complex midi files?

Thanks for any help on this,

Jonny
