The files appear in the addons select in Custom, and in the playsound event. When you event it (onActivate Self playSound Trombone), it doesn't play the sound. I got the base code from Sound_Beeps, and I just changed the sound names. I will try setting it to mono right now, and what do you mean by generic names? In Sound_Beeps, the sounds are just labeled Beep_EKG, Beep_No etc.
