I have Sonar 6 Producer, a bunch of mics and some good guitar gear. I'd like to be able to record guitars (acoustic and electric), so the recorded tracks can be used in a professinal recording. The thing I'm missing is an audio interface. So far, I've used a Tascam US-122, which works ok, but not really satisfying. I guess I don't need more than 4 channels. I'd appreciate any help and tipps on interfaces. Thanks!
