MIDI messaging is going "wacky"

Can someone in the developers section please re-visit the MIDI side of things? The BB is starting to do strange things MIDI wise -
EG: enter in a volume under 128 (using BF 6B) and it actually loads a default BF 6A (those over 128) - enter in a volume message (BF 6C) and it changes the tempo…there are others but that should give you an idea.
