BTW, I just started to use JACK (it works great with the realtime-lsm
module and my new soundcard). Wouldn't it be quite easy to add more JACK
output ports to traverso? Instead of "Master Out", just create a bunch
of outputs like "Playback <N>" and for starters apply the sheet gain to
all of them and use the first two for rendering exports.

Another thing regarding JACK in Traverso, I've noticed that if the JACK
samplerate isn't equal to the one used in Traverso, the playback speed
will be wrong. Perhaps this is fixed in CVS?

I'd though JACK would have built-in samplerate conversion so that
clients could connect with different rates and all was converted to the
actual hardware rate, but I guess this isn't the case?
