MainStage is transposing everything up by about 0.5 semitones...
I am new to MainStage 3 and have my M-Audio 49 key station plugged in to my MacBook Pro (High Sierra) and am using my M-Audio Mobile pre as interface. Every patch in MainStage is a semi-tone too high. I am just learning to use MainStage and haven't played with any of the default settings. Transpose is set to zero. I can transpose each instrument up a semi-tone to get it to play in tune, but that shouldn't be necessary.
When I check the midi settings in the OS X Audio Midi Setup, it has the mobile pre set at 48 kHz. I read that it should be set at 44.1 kHz, but when I did that, terrible distortion noise was produced when playing the keyboard.
I've read of similar issues, but none of the suggested fixes seem to work for me. Any ideas as so fix this issue?
MainStage, macOS High Sierra (10.13.3)
