You can have bare-metal access via PCI as well. Nothing prevents you 
from bit-banging but the OS.

Since a hardware sampler is pretty much the same system, i.e. CPU + 
dedicated, bit-banged hardware, I don't see any difference in latency. 
After all, the key data is still transmitted via MIDI, so in the end 
your ISA-PC box is just an expander module.

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

Sheesh, Google is really a bitch :)

But to spare you the searching, I downloaded the datasheets and 
programmer's reference from 
	http://mail.lipsia.de/~enigma/neu/soundconfig.html

and put them here:
	http://itec.uka.de/~buchty/datasheets/

into the "Custom Chips" section.

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

And since I'm forced to clean up my work room next weekend (to 
temporarily turn it into what it's officially labeled, the guest room) I 
might even find it.

Assuming it's *there* and not in <dramatic pause> THE BASEMENT 
</dramatic pause> where I keep those databooks and old magazines which I 
had to remove from the kitchen cupboard and the living room.
