Hi Tom.
Here be dragons! :)
I've been wrestling with bank & program changes since my first hardware synth
in 1991 - and I'm still not sure I know what I'm talking about.
However, I still have 3 hardware synths (although seldom used now).
None use both MSB & LSB
One uses MSB, the others use LSB
The two that use LSB actually send both (zero for MSB). The other one only
sends MSB
All send a program change whenever they send a bank change.
None want a bank change when *getting* a program change they remember their last
bank setting (including over a power cycle).
One of them, QS300, can accept a program change 'silently' to a non-sounding
channel which will then pick up cleanly on the next note, but if you send a bank
change as well the entire sound cuts out.
They all only transmit on one channel, but will accept MIDI on all 16. Bank
is applied to all channels whichever channel it's sent on. Program is channel
specific. This makes sense as bank changes are swapping out ROM sets, program
changes just select a voice within the ROM.
My most recent one is mid 1990s so things have probably changed considerably
since then. I would expect them to be even more flexible. You can probably do
silent bank changes now. As far as I know there are still none that use both
MSB & LSB though! There is *no* sensible plan as to what bank numbers are used.
1,2,3,4,5... forget it!
With all of this I think the only safe thing for Rosegarden to do is to pass on
exactly what it gets without trying to make any interpretation. How it wants
to represent banks for display purposes is really up to you, but currently it
changes them (seemingly just LSB) and I think that is quite wrong.
Since working on Yoshimi, I've developed an even more keen interest in this and
in order to try and keep up, our bank changes can be set to receive either MSB
or LSB, and work across all channels but have no effect at all until there is a
(channel specific) program change. As there is no physical ROM the synth
engine only knows about voice patches currently in memory. We effectively have
an equivalent to an alternate MSB or LSB as we have a control that sets the
entire directory structure that banks are read from (also silently). The test
file checks that all these work including trapping invalid bank and program
changes. You'll notice there are changes on one channel while others have
continuous notes.
I would guess that most soft-synths would work in pretty much the same way if
they accept MID controls.
P.S.
I'm not on the developers list just the users one. If this is getting too
involved for users I guess I could subscribe, but I'd actually rather stay as I
am :)
P.P.S.
As a matter of interest, I've attached the most complete MIDI chart V2 I can
find. It's actually a merge of several!
