Keep in mind tough, that breathcontroll is nothing but a midi parameter 0 to 127 that can be controlled by breath pressure...

Huge advantage, it works very natural, but the same effect can be archieved with any modwheel or expression pedal.. just make sure it triggers the same parameter as the breathcontroll
If I use an expression pedal or play my midi accordion with bellow dynamics (essentially CC#11) and use a breath controller, would it be like driving with two gas pedals? What would be the major difference between expression CC#11 and the breath CC messages?
