The idea of installing a pressure system to a foot-pumper is fabulous. The main problem I see is the pedal return: the return springs would have to be strong enough to compress pressure in one section as well as create vacuum, but not be so strong as to make pumping an Olympic event. And how about using a simple valve to pouch pipe chest like a single rank Coinola that would minimize vacuum usage?
A nice rank of flute or violin pipes could be built into the piano if all of this was double. Any thoughts on the spring tension fro pedals?
