Core Audio sample Rate not allowed
I am running mainstage from a Yamaha MoXF6 into a Mac Book. Then the signal is going to an M-Audio Fasttrack interface. From there it is going to the amp. When I try to run the purchased concert in Mainstage with this set up I get the error - Core Audio: Sample Rate 44,100 not allowed. If I use just the external headphone jack, I don't get this error but the sound is not great quality.
