Hello. Good news! I found following from www.deja.com, Deja News, with
power search "audio & memory & play & instant".
Well, is this ok or what? Date is 1995, i.e., two years earlier than
the Gigasampler patent.

),
: and some enginering and programing time -- you could easly create

and
: near ( sub 10ms ) access to any audio on the cd-rom ??
You've just described a hard-disk recorder. But, if you want
to save some money, and you don't plan to edit the music, you
could get by without the hard drive. Substitute a few megs of
RAM; and if you need *INSTANT* access, cache the first second
of every "cut" in memory -- then, you could start playing any track
with only a few microseconds delay. Of course, anything
quicker than about 50ms seems instantaneous to mere mortals.
...it's "only" software,
Mark
