I totally agree. I think that one of the candidates to start the
real-life Linux Audio Revolution for non-computer-geek-musicians are the
acoustic guitar + realtime LADSPA effects and of course the outstanding
zynaddsubfx patches for the keyboard players. (For the electric guitar
disto, I have finally assumed that analog rules.)
But yes I think that before we should try to solve some problems of
usability for live-use... now there's too much mouse-work.

yes, again, I agree. I suggested that for the qjackctl.
there's a partial implementation of the idea with patchbay (the
automatic connection of some applications) but maybe with your feedback
we could explain to the developpers what we are missing. I'm not a
native english speaker and i've got some problems to be really precise...

we're all waiting for the ardour 1.0 which is slowly becoming a reality
and will fix all this...

I think that this is not a problem of jack but a problem of the
applications which use it. Actually ardour already has a mechanism to
reconnect to jack when it loses its connection. Now it doesn't work
(beta29) ;( but it seems that in the future will do so.
I don't know... Any jack expert could help to see what should be done to
fix this?
