We have received numerous requests from musicians and composers to develop a replacement for Yamaha's breath controller BC3A.
The result is the MIDI Breath Controller, which has the same function as a combination of the BC3A and the "MIDI solution" converter box but with a USB interface instead of the older standard DIN connector.
The MIDI Breath Controller uses a novel signal processing algorithm to transform the breath pressure signal to MIDI cc messages that let you add realistic expression to your performance. This is extremely useful for live performance with synthesizers and DAW's. It gives you excellent control of pitch, expression, velocity cross-fade etc... of soft synths and sample libraries
