When my pedal & iPhone 5s are properly paired and working fine, I get dropouts of song playback. It only seems to happen when I'm changing patches or engaging wah on the FX100. I suspect that the transmission of the patch and status changes from the FX100 to the iPhone interferes with the audio bluetooth signal momentarily. If this is the case, is there a way to keep the bluetooth audio running and keep the FX 100 from passing patch info back to the iPhone at the same time. This makes gigging with the backing tracks pretty difficult.
