I purchased an old beige G3 from a flea market that came with Logic 4.5.1 loaded, I was excited. I stumbled around trying to figure out how the program worked, and was able to make some sounds almost like a real recording engineer. I had a power surge of some kind and almost lost everything in my computer. So now when I activate Logic I can play wave but for some reason when I load midi it loads I can see it playing but I get no sound. I'm really green when it comes to trouble shooting this program as it came with no manual. the only driver I have that seems to get any sound is mac av. I have downloaded digi design, asio etc. But I get nothing!!! what am I not doing? I know I'm close but really frusturated.I hope you can walk me through the steps. Thanks thevoice
