Talking about MIDI controllers in general, there is one that I've been
interested that simply has not been practical up till now, and that is Program
Change.

Yes!! That's the big one I want too!
Recently, while working on a new composition I discovered that now, you can
indeed, change voice patches in a non sounding channel while others are
sounding. You only get a slight disturbance in the sound if it is one of the
very large patches that you are loading.

Very interesting, and suggests that program change implementation might not be
as problematic as I've been imagining.

This means it is practical to do both voice and voice bank changes on-the-fly.
There aren't many soft or hard synths that can do that! With some care and
thought, while still only having 16 channels you can have a *lot* more
voices - 16384 in theory :)

I don't have any idea how much effort that would take to implement, and I'm
quite aware that our long-suffering dev (yes, that's you Cal) can only work on
a limited set of priorities at any time, so please regard it as a 'that would be
nice' rather than a 'the sky will fall without this'.

P.S.
No I'm not planning on creating new patches to fill all those slots :P

... which does remind me of one small point needing consideration - for managing
bank/program changes, I do believe it'd be simpler if the number of banks and
the
number of programs per bank was limited to 128. Currently the number of
instruments (or programs) per bank is 160. You can do a multi-byte program
change
to accoomodate > 128, but it'd probably be easier if to use single byte with the
128 size limits.

cheers.
