Re: "smart" transposition of key signatures

[Kieren MacMillan]

Hi all,

Thanks for the quick response.

Yes, splitting the variables was going to be my fallback answer…
But (to quote Louis Mordell, as I just did in only of my number theory papers): 
"one could only wish for a simpler solution".

A solution in which Lily was able to Do The Right Thing™ might also solve the 
long-standing "multi-instrumentalist" problem (i.e., instrument switching in 
the middle of a piece requires key signature changes, possibly normalized, etc.)

If anyone has time on their hands and is willing to take some of my money, I'd 
love to discuss this whole problem space.  =)

Best regards,
Kieren.
