Wait a minute...  I looked at this again...

iiwusynth: prog 9       128     0

That's its initialization state...  Putting the "standard" drum kit (bank=
 128,=20
program 0) on channel 10 by default.=20

Then we change it to bank 0-0 prog. 0 and get:

iiwusynth: prog 9       0       0

(It plays a piano...)

Now I flip to the MSB 0 LSB 0 bank, prog. 1 (actually 0)

and iiwusynth says:

iiwusynth: prog 9       256     0

Bingo.   Where's the 256 coming from?

Odd that RG could have such a huge problem, seeming on the surface to be=20
doubling the MSB value (2-0 is bank 256).  It can't be thus, because my G=
S=20
bank works fine (just confirmed), and everything in GS is selected on the=
=20
MSB, ergo a simple +1 problem cannot be.

Mysterious.

So if it thinks 1 0 is 256, it would think 0 63 is 128 then, maybe...

iiwusynth: prog 9       63      0

Nope. 0-63 comes out right.

But if I try 2-0 (should be 256) I get

iiwusynth: prog 9       512     0

I wonder who's doing the wrong math here.

127-127 should be bank number 16,384

It yields:

iiwusynth: prog 9       32639   0

Doesn't make any sense at all, that one.  Doesn't look like a sign rollov=
er,=20
so why isn't it 32768?

One of us has a serious bug, and since the GS stuff works flawlessly, I t=
hink=20
iiwusynth must be borked.  I'll bet _it_ has the +1 problem.

I'll go try to find it.  Rosegarden benefits indirectly.  The other stuff=
 I=20
was going to do can wait a bit yet...
