Replying to multiple posts:

Pedantically, that's wavetable synthesis though, not sampling.


Well, 4 kb samples, thats distortion, not sampling :-)

Sorry, I didn't write clearly. I want to do it all from DOS, so if drivers
are necessary, it wouldn't work for me. I need bare-metal access.

What I meant is that you get lower latency from an ISA card based sampler
than you would get over MIDI with an external sampler. Especially if we're
talking sample editor latency...

For the EWS-64's ? I looked into some time ago, and from what I could
gather, only MIDI control and possibly wave-stream control are disclosed.
The sampler is not "user programmable".

But am I wrong? That would be great! :-) Where can I find those datasheets?

BTW, does anybody happen to have datasheets and other info for other SAM
chips, the esp. the 8905 ?
