Dear Sirs,

I have a problem between MainStage and Mobile Sheet Pro. I try to change Mainstage's Patches by Mobile Sheet Pro (connecter with Usb) but it doesn't work. Any suggestion? Thank you

I'm going to need a little bit more information. What is MainStage, what MIDI commands is it expecting an on what channel, and did you see MobileSheetsPro prompt you for authorization to connect to the MainStage over USB when it was first connected? I need to verify that MobileSheetsPro is actually connected to the device. For example, if you go to the MIDI listen dialog (MIDI tab of the song editor, last icon on the right side), do you receive messages from the MainStage?

Thanks,
Mike
