The new MRTaudio controller chip has been re-programmed and has new features. First, it has much faster response. Second, it is programmable to send different MIDI controllers and after touch. Mod Wheel (CC 1),Breath Controller (CC 2),Volume (CC 7) and After touch. default setting Volume (CC 7) you can use 1 channel or 1,2 channel and last section 1,2,3 midi channel. default 1,2,3 midi channel BOOST your extra Gain for yamaha bc3 section with yamaha bc3.
