Hi John,
I have had still to fathom out how to get things just the way I want
them automatically.
After booting up, I start QjackCtl which seems to start Jackdbus quite
happily. I then
start and stop various things, and then configure the connections with
QjackCtl.

I had some problems when I plugged in a keyboard, as it didn't appear to
Jack, but then
I was advised to run a2j (alsa-to-jack) which makes a connection between
the keyboard and
Jack, then I can connect that to my sequencer program (home-grown.)

This list is a great asset for us. Lots of knowledgeable folks around
who are willing
to offer advice. Thanks folks!!

Bill
