"Wind Machine

Wind Machine and your BC 1 or BC2 Breath Controller (not provided) add expressive power to your keyboard performance. Brass patches can punctuate or pad according to your whim, not to some pre-programmed attack setting. Your sax solos will turn heads with their authenticity. And layered string sounds can fade in precisely where they're needed while your hands and feet are free to control wheels and pedals.
Compatible with everything. Wind Machine interfaces to Korg, Roland, Yamaha, Ensoniq and the rest! No longer are you forced to use your breath controller with only one brand of MIDI synth. Any MIDI keyboard that will respond to MIDI Volume, Aftertouch,W Modulation, Breath Control, Pitch Bend, Expression, Foot Controller, or Pan can be controlled by Wind Machine.

It's a natural. Blowing into a mouthpiece is the most natural way to enhance keyboard performance. Wind instruments have been designed around this principle for centuries.
Alone, keyboard Aftertouch isn't as effective because when you release the keys, the
effect goes away. Modulation and Pitch wheels alone aren't as effective because they $ don't allow you to play chords. But when combined with Wind Machine, all of these
can be used to create vastly improved expression capability.

Easy Hookup
A flexible input/output configuration means ·· ·nd Machine can fit seamlessly into any setup. The si·lest way is to use it to send eontrol signals to the MIDI input j ack of a keyboard synthesizer. If the Mn·I setup involves a master keyboard and external modules, W· Machine can combine incoming signals from the master w· it's control signals and then pass them on to a se·encer or sound modules.

Wind Machine can transmit the most popular control parameters to keep it simple. Most MIDI keyboards respond to Modulation. Aftertouch or Volume so you won't have any problem finding one compatible with your synth. Any one of the 1 6 MIDI channels can be selected as well."
