Thanks Steve. I understand that. The xruns when clients
connect/disconnect are actually the only ones jackd is reporting. The
others are reported by ecasound when it exits.

Will do. I'm going to slap together a non-realtime chain settup with
ecasound's builtin oscillator controllers instead of midi-controllers.
This will just print to a file, no realtime audio output, and will only
use ecasound and analogueOsc. So it should show if the audio glitches
and zipper noise are related to realtimeness or midi issues. I'll also
do a realtime version with ecasound's controllers.
I have vague memories of people saying on the alsa lists years ago that
ymfpci chips suck. I'm only using mine for a midi i/o. I happen to have
an es1370 sitting at home unused. Would it be worthwhile to stick that
in the box and see if the midi on that works any better? or is this
unlikely to be a midi problem at all?

Well, maybe. I've wondered at times why there isn't a swh-ladspa mailing
list. I've never managed to get into wiki editing for various reasons. A
mailing list might be simpler to set up. If you want I could probably
host a mailman list on my server at home. Heck, we host the portaudio
list here at work, so I could probably convince the bossmen to host a
list for you, too. Just a thought. I suppose you would have already
been hosting a list yourself at plugin.org.uk if you wanted that.
