I'm running jack and all the clients as myself. I can't tell you exactly
what the error messages are right now because I'm at work, but it was
something to the effect of "client not found", or "unable to conect to
client". Yes, client, not server.

Well, if I get to the point where I need studio-quality sound, I'll go out
and buy a real, studio-quality synth module before I use the software
synths. Granted, they're extremely cool and sound totally awesome but my
system is only (!) a dual Athlon MP 1800+ with 2GB of RAM, and the
software synths just crush it when I get 16 or so voices with effects
going, while simultaneously trying to record the whole thing with Ardour.
That, by the way, is where I was seeing the drop-outs that started this
whole conversation.

Ok, I thought I saw that happen on the last reply I sent. I'm new to the
whole concept of mailing lists; I only use two others, both run by Red
Hat. The Red Hat list servers apparently re-write the message headers so
that the Reply-To always points back to the list, rather then the post's
author. I'll have to pay closer attention from now on, and make sure I hit
"Reply to All".

Thanks again,
