I would like to hear it too. I'm very new, in fact uninitiated, to
synthesis. Is there a good tutorial (for newbies!) somewhere for how
to .. do it?

...

As a side note, I hope that discussion of file-sharing or a
sample/preset database hasn't fallen by the wayside. This would be a
perfect time for such a thing! I have about 40GB of transfer per month
that we can use, but if it goes over... Then I'm SOL. But at least it
would be a start. If anyone knows of a website framework suited for such
things, using PHP/Perl & MySQL (this is what is on my host) then let me
know, and I could set it up.
