Hi. I'm not sure what the problem is, but sending a turnoff message from this Pd patch, if there is more than one note playing, crashes Csound and Pd. It happens whether I send a message to instantiate instrument 10 with the turnoff number as a p-field, or I set instr 10 to run all the time and only send messages when it receives a voice number through chnget. I'm using decimal instrument numbers. If only one voice is playing, it turns off fine; if two are playing, it crashes. If I play the list of notes loaded in the [qlist] object, it crashes as soon as it reaches a noteoff. If the commented parts of the .csd file are uncommented and the lines with p4 and turnoff are commented out, then it should work with the chnset messages from Pd instead of the instr 10 events. If, instead, I comment out the line for turnoff2, and print the output of csoundapi~, it in fact prints the outvalue of koff *twice* each time I hit instr 10, even though it's set to turnoff immediately. Any ideas what could be wrong? Thanks. -Chuckk -- http://www.badmuthahubbard.com
