Yup. Personally, I think it's quite sensible to limit sample-based
"synths",
i.e. "romplers", to 12-note tunings, and the +63/-64 system (XG & GS)
is neat. I find samples can begin to sound quite terrible if shifted too
much
from their original pitch. And many of these instrument have less perfect
samples, the Yamaha XG devices cram the 128 GM sound set into 4MB !

But (!), there is a work around on XG and GS instruments (GS can hold
individual tunings on individual channels, oui ?) :
Simply use your keyboard's splitting function, assign each split region
to a different channel, and work out the (rather fun) puzzle of
tunings the tables to get different pitches in each keyboard "octave".
It works for many tunings.

Hey, thanks fo these, John. Very handy. I was quite happy to stumble
across
them after accidentally clicking on my bookmark for your site.

I generally end up making different sounds for each tuning, but that's
mostly because the ASR-10 makes it difficult to do otherwise.
