The Yamaha BC2 Breath Controller is a MIDI device designed to be connected to a synthesizer or MIDI keyboard. It converts the strength of the user's breath into MIDI Breath Control data. The device features a headset design for comfortable wearing and includes a washable mouthpiece.
The BC2 can be connected to a synthesizer or MIDI keyboard to control MIDI Breath Control data based on the strength of your breath.
You can alter the amount of breath necessary by using the drain cap at the end of the mouthpiece pipe.
Turning the offset screw clockwise results in a higher output when you are not blowing into the controller.
