Hmmm... strange.  You are running jack as a regular user (and starting
the clients from the same user)?  What do the messages say from jackd
when you try to connect a client (i.e. click on the messages button from
qjackctl or run jack with the -v flag and check the terminal output)?

I don't use MIDI very often, but I will suggest that any on-board synth
is probably going to be very crude.  Have a look at some of the software
synths Fernando has included with the planet.



PS You sent this to me directly, so I've replied back to the list just
in case anyone else may have some advice (especially concerning the MIDI
point).  It's usually best to keep these discussions on-list.
