Re: [Jack-Devel] Using Jack

Yves, you don't need Jack, and even stronger.. you shouldn't use jack for what 
you're trying to do.

As John Emmas has posted earlier, look into something like portmidi: 
http://portmedia.sourceforge.net/portmidi/

You're not looking to route audio/midi and/or connect devices, you're looking 
for something to hook you up with LoopBE, which - from what I understand - is 
what portmidi will allow you to do.
