Shot in the dark, but this I've tried everything and everywhere and this forum is a last resort, before I think about buying new hardware.
I am using a Tascam us-122 with Windows 7, Cakewalk Home Studio Sonar 7, rewired to Reason.
And it's giving me a hell of a time. I've been using the same set up (except Windows Vista and Home Studio 2004, until recently) for years and it has worked perfectly. Basically, things work fine until spontaneously, when either recording or having the input echo on, it will feedback. It's as though it suddenly changes the input to it's output and then feeds back. Sometimes it goes as far as to just recording what the computer is playing, and ignoring the input altogether. This change will literally happen with no changes in settings being made - sometimes even mid-recording.
[note that this isn't your standard mic feedback squeal - it's more robotic, hard to explain]
This happens most often when ReWired to Reason. I have the most recent drivers for everything.
Has this happened to ANYBODY?! ANY ideas?
