Peter,

I don't know for sure how the Yamaha P-85 handles it.

Though, you could try to do a program change to a distinctively valid 
instrument (piano, string, nylon guitar), then try to set it to use the same, 
or one of the other instrument (program number) on a different and invalid bank 
(i.e. bank #111, ...) and see how it handles that program change.

I also think that there are some sound banks that have only a few instruments 
(not all 128 instruments).  So midi, or style files from one sound module (or 
keyboard) will generally sound different from a different sound module, because 
non-existing selection reverts to using the basic GM (bank 0) 128 instrument 
sounds.

If you look here:

   www.mboss.force9.co.uk/miditext/Xgvoice.txt

you can see someone had taken some notes on some XG instruments mapping there.  
Note the bank and prog combination.

I believe some Yamaha keyboard manuals do list their instrument map, especially 
the more costly models.  Not 100% sure, but if interested, you can search the 
Yamaha keyboard manual library for Tyros, Tyros2, Tyros3, psr-s900, psr-s700, 
psr-s500, psr-9000, psr-3000, psr-1500, psr-1000, or your own P-85.  I believe 
Yamaha also has text version of some of their keyboard manuals, too, which 
would help if you want to take personal notes by extract some of those mapping 
table.
