Let's see what we have here...
(sorry about the romanized transliteration, but I can't manage to copy-paste Japanese text without being converted to question marks by the forum)
Shitsumon desu.
GS no MAP shitei (55,88,88P,etc) koto ni, SF2 o settei dekiru you ni narimasen ka?
Translation: I have a question for you. Is it possible to set (assign) a GS MAP (e.g. 55, 88, 88P, etc.) to a soundfont?
Mazu, watashi wa soundfont ga hoshii wake dewa nai desu.
Translation: No,no. I don't want / need any soundfonts.
Onaji BANK demo MAP ga chigau to, oto ga chigau n desu.
Rei:
Instrument MAP bank prog
Dist.Gt. 55 000 030
DistortionGt 88 000 030
toka
Piano 1d 55 016 000
European Pf 88P 016 000
Translation: Same bank (and same program), but different MAP - the sound is different.
For example:
Instrument MAP bank prog
Dist.Gt. 55 000 030
DistortionGt 88 000 030
also:
Piano 1d 55 016 000
European Pf 88P 016 000
What he really needs is VARIATION banks (CC #32 / bank select LSB support).
It's a feature that's heavily used in General MIDI Level 2, Roland GS and Yamaha XG MIDI standards:
"The most notable addition of the Roland GS standard was the ability to address multiple banks of programs (instrument sounds) by using an additional pair of Bank Select controllers to specify up to 16384 'variation' sounds (cc#0 is Bank Select MSB, and cc#32 is Bank Select LSB)."
"Accessing the massive sound library of the SC-88 Pro is possible with Bank Select commands (via MIDI), plus you can also select sounds from the front panel. The pair of buttons labelled 'Instrument' select a Part's main sound, while pressing both together takes you into a variation mode, where the banks of variation sounds can be accessed using the same buttons. It's just as well that the extra banks are easily accessible, since some basic sounds are provided with as many as 31 variations. Of course, the SC-88 Pro is fully compatible with all GM and GS (Roland's extended GM protocol) song files, and complete compatibility is provided for files written for the SC-88, SC-55 and SC-55 MkII, and the old CM-64."
