Another MIDI question - soundfonts

[Chuckk Hubbard]

Hello.

I'm writing a microtonal sequencer, and I don't want to use MIDI per
se, but I'd like to be able to load standard sample banks to play.
The only standard format I'm familiar with is soundfont, and it seems
to be the most popular; if anyone knows of others, especially for Mac,
which I believe most of my software's users will be using, I'd love to
know about it.
And, does anyone know a python module that will allow me to load in
soundfont files and make use of their info? I'd like to be able to
remap the pitches, of course, but using the same presets and such.

Thanks.
