I am recording a demo with my band. Weve been recording to a Roland VS-890 (when we need to multi track simultaneously) then we are sending two tracks at a time out the digital out into an M-Audio Audiophile USB. Then the tracks record to Adobe Audition. Some tracks are coming over fine. But some tracks pitch is being altered as much as up a whole step. Has anyone else had problems like these? Why does it happen? Where in the signal chain does it happen? What can i do?
