	Hi, Steven, Thanks for the response. My problem is turning off instr 1 at the appropriate time; instrs 2 and 3 finish fine. Otherwise instr 1 keeps right on computing silence until its duration says to quit. The events for 2 and 3 are spawned by a controlling instr 1, which passes them their lengths. Unfortunately, instr 1 doesn't know how long to stay on until after it examines the files it is supposed to play (and when).
