Get track of actual MIDI Note-ons
Feb 18 2017 | 6:18 pm
I would like to have a list which includes notes which are actually ON. These note-ons would be erased from the list as soon as a Note-OFF arrives.
Does anyone know of an object, external or code chunk that performs this task?

I added my spicy touch of spaghetti coding, and i already have what i was looking for, which i share here, just in case someone finds a need like mine.This is part of a larger patch that analizes a 64*35 pixels image, and generates a note-on for each pixel that goes from black to non-black, and stays ON until the pixel goes back to black.Because 64*35=2240, which is far beyond the 127 notes possible in a MIDI channel, there are at least 17 (2240/127) repetitions of the same note pitch value in this 64*35 matrix, making it possible to have many simultaneous note-ons for the same pitch if enough pixels which share this pitch are lit. Problem comes when just one of this pixels goes to black, because a single note-off is going to switch off all the notes off, but there are still the other pixels lit but with no sound. I could solve this by generating a note-off just if all the number of note-offs received equals the actual hanging note-ons.On the other hand, if a note-on for a specifical pitch has been generated but still waiting for a note-off, new note-ons for the same pitch are ignored.All this makes sense in my situation, as i am working with a real pipe organ which has its own specificities, limitations and of course, advantages!Thanks everyone for your help!
