Duh! :-) Of course I didn't mean ISA or PCI made any difference (at least
not that PCI would be slower than ISA)...

Yep, but if you are doing PC-sequencer -> PC-midi-interface -> "Hardware
sampler"-CPU -> "Hardware sampler"-soundgenerator, you get longer latency
than PC-sequencer -> internal sampler. And if you have an onscreen
sample-editor on the PC, you won't have hair left for long if you do
Waveeditor <-> 1 minute MIDI SDS. <-> sampler.

My point was really that the chameleon or hardware sampler (from Ensoniq,
perhaps?) that only has sample-transfer via SDS, while being great in many
ways, aren't really suited for PC-editing. I know Ensoniq had this feature
of dumping a for-screen-only version of the samples if you wanted to edit,
and in theory it's a great idea, but it never worked in real life. So my
point still stands: I need an ISA card. And anyway, I want an ISA card ! :-)

Sheesh, Google is really a bitch :)


Hey, I did google first... Found some, but not the appropriate info...
Thanks man!

BTW, http://www.anime.net/~goemon/linux-sam9407/ says to read the
mailing-list address from an unreadable GIF. Anybody have the address?

Hmmm, I think I have the datasheet *somewhere* in form of dead wood.

Great! BTW, on the SQ80-list IIRC you talked about taking new photos of the
SQ/ESQ schematics. If it would help you in any way, I could offer to do the
cleaning up work with an image editor, so you could just use the highest
resolution your camera can use (perhaps photoing close-up fractions of the
schematics if that gets a better picture), send them to me, and then they
could be stuck on my harddrive for a couple of months, and eventually you
get semi-clean schematics in on-line-publishable form! :-)

Hey, old tech-junk is what basements are for, right? And attics, and
garages, and the space under beds, and closets and car trunks and your
parents entire house :-)
