Re: organ - off topic

[J Martin Rushton]

A sustain pedal wouldn't be possible, since an organ has no dampers.  An 
organ pipe sounds just as long as the key and stop send air to it.  A 
sostenuto mechanism might be possible, though personally I've never 
heard of one, by simply keeping the key or part of the linkage 
depressed.  Your question is interesting though, since it appears you 
are looking at the wrong end of the telescope!  sostenuto was developed 
to allow the piano to emulate the organ.  See 
https://en.wikipedia.org/wiki/Piano_pedals#Sostenuto_pedal et seq. for 
more info.
