very true, or I could use an opamp/comparator, or drive a periph based on the out (I am having visions of a stuffed monkey crashing cymbals together on top of my case, ....most annoyingly useless mod ever?!?!) in any event, you have clarified my thoughts on damaging things I cant replace right now I will start investigating, thanks gigs Curt!! -- -- NOT sent from an iphone,blackberry,Nokia, or any handheld. -- I'm a PC(x86 AND ppc) AND I RUN LINUX!!!
