I just bought a USB eprom burner off the bay, so I'll be able to mess
around with "attempting" burning new sample eprom's soon.....
Too bad they aren't all jammed on one eprom, as that would make it ez
to use a larger size, and add switchable banks (by toggle the extra
address lines). I guess it makes it a little cool by them being
seperate, cause then you could have different soundset combos.... i'd
probably just do it to the interleaved ROMS (not crash & ride roms)...
Only problem is that large eproms & parallel SRAMS are expensive,
about 36 bucks a piece for battery backed 1mb SRAMS....but you could
fit quite a few sample banks on 'em (ie. 32). I don't know if Eproms
go up to that size
I know someone though email communication that understands how to
interleave samples on Eproms, i'll have to grab the visual basic
program he uses.
