Wow, first time I've heard that! :) That would have come in handy in that
past, many times. I don't seem to have that file though.

Something like this:
soundbyte.b = peek.b(*soundpointer+offset)
would get you the byte at that offset (0 being the first one obviously)...
If you wanted a copy of your own to play with though you'd need to do
something like:
dim soundcopy.b(soundsize)
copymem_ addr xbsound(soundnr), &soundcopy(0), size
Or, you could allocmem instead, but the array of bytes should work just as
well.
Hope this helps,
