I *think* that MIDI out is done via /dev/sequencer - I forget really.
However I don't use MIDI out at the moment, just audio out using the
portaudio. I have used it - it does work - but I have no use for it, and
I have forgotten exactly what you do to get it (soemthing to do with
Timidity I think).

None of this should impact HAVE_JACK development: it *must* be trivial
to turn off the portaudio stuff when HAVE_JACK is defined. I can't test
it so I am not the person to do it, but I can find the place it that is
a problem.

version of what? e.g. I have libjack0.101.1-2-dev
and other things with jack in the name, always the latest version (as
reported by synaptic). I recall trying to install jackmidi but giving up
because of an interminable dependency chain. I don't really understand
all this package stuff...

Again, it is the latest (I have been taking the updates, after starting
with a netinst of Debian Etch).

Fixing something that ain't broke is naturally going to be low priority
- as I say, not starting portaudio if HAVE_JACK is defined will be a
trivial change.
Also I suspect that portaudio is much more reliable as cross platform
library - it's been around a long time. I guess the Windows Denemo will
be using it for quite some while, even if everything we want in terms of
audio feedback becomes available via Jack on linux.
