EDIT December 4:
THE PROBLEM: has plagued me for months, and is finally driving me completely insane. My poly~ is receiving MIDI notes from my keyboard. It's getting all the note on and note off messages. But every ~10-90 seconds when I'm playing, one of my poly~ voices just won't shut off. This happens under all conditions: even when I just play 1 note very slowly, eventually it'll stick.
THE LEADS: The only way for me to get this rogue poly~ voice to shut off is by going inside of the poly, and manually banging a 0 into the adsr~ object. This is my best lead: I suspect the rogue poly~ voice is in "busy" mode, and won't accept data from outside of poly~ (but why would this include the "allnotesoff" message and the note-off message?).
I can also get this voice to turn off by holding down more "voices" than the maximum I set for poly~
I attached some screenshots. the screenshot from the Max window shows poly~ is definitely receiving all its MIDI on/off messages, through the shown (midinote $1 $2) message. Yet that second note in the print window never turned off!! Resending that (midinote 62 0) again didn't change anything. I had to open the offending poly~ window, and sent a (62 0) message from within.
This is driving me nuts. Any help would be so appreciated.
