Hi Frank,

The technoboy here uses ALSA sequencer. Yes Qtractor still uses and relies heavily on good old, proven ALSA sequencer for all MIDI stuff, so there's no issue whether JACK MIDI is up to the task or not.

Anyway, JACK MIDI is still rough in the edges, and incidentally it was just today, a few minutes ago, that I've committed JACK MIDI support for QjackCtl.

On the other hand, as I'm still using still and most of the time my own almost-vintage external hardware synths and, you guess what, technoboxes ;-)

Personally I have no good use for JACK MIDI, which I'm sure its primarily intended for running locally properly enabled softsynths, that meaning the same operating system image and host machine.

But, nevertheless, that's all in my agenda :) Just can't predict when it will make into the code.

About version numbers, I'm almost sure that any recent Linux distro includes all that's necessary to build and run Qtractor. At least, don't pick up anything older than a single year time frame. For the facts, and from memory here goes what it takes as sane/minimum requirements:

qt4 >= 4.1
jack >= 0.101.0
alsa >= 1.0.9
libsndfile >= 1.0.11
ladspa >= 1.12
libvorbis >= 1.0.0
libmad >= 0.15.1b
libsamplerate >= 0.1.2

Pretty baseline, eh?
