I don't do the kind of stuff where this issue arise and I haven't spent 
as much time thinking about this as others have, so this is just a 
question from someone who is just looking at this superficially.

Would there be an issue of someone switching modes so that FluidSynth 
sees a sequence like this:
[mode 1] LSB PC [mode 2] MSB PC
where the MSB is supposed to be interpreted in the same way as the LSB.

Do Bank Select MSB and LSB need to be cleared when a PC is received to 
deal with mode changes? Can they be cleared? Would this be a valid sequence:
[mode 3] MSB LSB PC LSB PC
where the second PC is intended to continue using MSB unchanged?
