Is it possible to send an audio signal out of a computer into external hardware processer and record it back on the same computer without getting a feedback loop? Or is that impossible? I was thinking that maybe some soundcards would be able to do something like that, but I'm not sure which ones. If not, I'm thinking I'm going to have to burn my track on a CD, and play it back on a portable CD player or something and have that go through the effects processor and into the computer for recording. Will be a pain though and a very slow way of working.
