RE: EDP - newbie problem - feedback @ 100%, but loop fades away ...



andy sent me some crystals when i had this problem (thanks again)
and it helped, but the problem didn't really go away until
i installed loop v4.
i hadn't tried the codec chip.
maybe if it happens again i will...

i'm curious, though, why would hitting undo help?
