   I'm looking at this right now.  It only has programs for five of the 
23 banks: Arpeggios, Bass, Brass, Drums, and chip.  My install of 
yoshimi has many programs in all 23 the banks.  Is this just me?  Should 
I wait for this to be finished?

Had a quick look at this - seems fine to me.

Well here's my go at it:

https://github.com/lorenzosu/rosegarden_yoshimi_banks

And here is an example .rgd file generated from the default banks 
installed (in /usr/local/share/yoshimi/banks in my case):

https://github.com/lorenzosu/rosegarden_yoshimi_banks/blob/master/yoshimi.rgd?raw=true

Haven't fully tested it but seems to work nicely with yoshimi set to 
receive MSB.

I'm back :)
The bad news is that this time next week I'll be down one wisdom tooth :(

NEway

Quite correct, but maybe I should make more fuss about yoshimi's "doc"
directory. There's a very detailed explanation of the root/bank/instrument
structure there in a text file called banks.txt :)

In short, Rosegarden is probably best off ignoring root and bank IDs, and using
just the installed location, simply taking the bank directory names. The
Instrument IDs however are an integral part of the filename so must be included.

The clever thing about the way this is structured is that adding new roots or
banks will never change the IDs of the existing ones (unless you lose
your .config/yoshimi/yoshimi.banks file somehow) and that is aimed purely at
those wanting to make bank and program changes via MIDI.

Also, the user can reorder roots and banks with new IDs without modifying
the directories/files themselves.

However, I have no intention of increasing the number of default banks so they
shouldn't change anyway.

Now I don't know if all that makes things simpler or more complicated.

Never mind... I figured it out: it's generated depending on the number 
of banks..

Misc/Bank.cpp:size_t idStep = (size_t)128 / (bankDirsMap.size() + 2);

I was confused because "chip" came last, but that's because it's 
lowercase vs all the other banks.

This means that probably one could do a script which generates a rgd 
file given a yoshimi bank root directory (at least the banks part)... :)

Cool.. Where does yoshimi pick the bank number (e.g. Arpeggios -> 5, 
Bass -> 10).. It seems *almost* alphabetical with the exception of chip. 
Actually it would be nice to have a script which could generate the rdg 
file on a user's system :)

Hmmm, now you mention it I dimly remember something about this from about 10
years ago! :o

The default installed set are in /usr{/local}/share/yoshimi/banks and are normal
directories of banks with instrument files in them. All the instrument files
have a 4 digit number prefix.

Now I must go, I'm supposed to be several miles away in an hours time!
