In Manchester recently where I witness a Bach recital. Am intrigued by the fact the console is wholly separate from the organ pipes, but am told by the organist that this is common with larger installations in cathedrals for instance.
The key strokes are thus relayed by to electro-pneumatic servos that operate the pipes.
In a way, that's what I'm doing with eVTOL, which is also a distributed power arrangement in which control motions are relayed to electrical units that effectively manipulate the air.
Interestingly the man at the keyboard says the very slight delay that this entails however as compared to mechanical linkages does affect the rendition of the piece.
Either way, Richard Bach would have liked the way that we're making music with eVTOL.
