MainStage flat a whole step ???
I just bought MainStage and i'm using is with a Fishman triple play for guitar. When I use instruments in Logic, it's fine. When I'm trying to use MainStage, with the same instruments, my sounds are flat one semitone and a couple of commas. The workaround I found is to insert the transposer down one step on the channel strip AND put the master tuner at 430 Hz to be in tune with my guitar. That's super weird, and not practical as I have to do this on every sound. I checked that the guitar is OK, and on the keyboard on the screen the note is the note of the guitar, also indicated on the fishman interface. So there is really something with Mainstage, but I cannot find out.
Help will be very appreciated. Links to resources to learn to use it quickly would be nice too, as I have a feeling that the sw is very powerful but totally non intuitive to use !
Thanks
