OK, check to see you have the latest firmware update and newest iPad Remote. If yes to both, try tremoving reinstalling the iPad Remote from your iPad. If you still hve an issue with the same two channels, try plugging your keyboard into a different mono channel. For the computer RCA input (45-46?), do you have EQ, etc control on the GLD surface? If so, sounds like asoftware glitch for iPad Remote, OR a wireless router problem. Try a different router and see.
This is like finding a bad channel on an anologe system, change out one thing in the line and test until you find the bad connection.
Good luck.
