Are there any Mac users out there that own a Tascam US-122? I use DP3 (haven't tried it in DP4 yet) a Roland JV-1010 and a Triton. I record mainly large orchestral works and experience quite a bit of phase shifting with more complex waveforms (like string sections). I already sent my Tascam to get checked out after every possible mix adjustment I could do (which is limited because I am pretty new to mixing) but I wanted to know if anyone else has had or heard of this problem.
