    Breath-to-Expression Converter for the Yamaha BC3A™ Headset
    BCXP Pro is a revolutionary addition to the world of keyboard technology. This device allows you to regulate your keyboard's volume with your own breath, giving it the natural modulations found in all brass and wind instruments. Rather than having the flat, uniform tones found with common keyboard strokes, the BCXP Pro reads your breath's pressure and translates it into power for each note you play. The softer you blow, the lower the volume. As your breath's pressure increases, the note becomes louder. This gives the ramp-ups and trail-offs produced by real wind and brass instruments.

    The BCXP Pro is a patented proprietary device that is American made and guaranteed to improve your performances in a way no other keyboard plug-in device can. All you need is a keyboard with an expression input jack and Yamaha BC3A headset to get started. By plugging the BCXP Pro directly into your keyboard's Pedal input, and plugging your BC3A headset into the BCXP Pro, you unleash new potential for producing a whole new array of realistic sounds.

    The BCXP Pro requires no special software or other devices (besides the headset). You don't even need a MIDI! Its simple settings do not require technical skills in order to operate: this is a true plug-and-play accessory.


    The BCXP PRO can be connected to most keyboards/synths through the Pedal Input Jack for controlling volume, expression or other assigned parameters. BCXP PRO has a 1/8" input jack to connect to the Yamaha BC3A™ and your keyboard with a comparable input array. BCXP PRO has an input jack for connection to an expression pedal (to merge an additional device). BCXP PRO is linear (0-127). BCXP PRO has a reverse button for reversing the tip & ring. BCXP PRO has two LED indicators: green for full battery, and yellow for low battery warning. BCXP PRO is powered by either a 9v battery or DC 9v regulated power supply (not included).
