Jack allows you to send audio in real-time between applications that are using it as an audio device. This tutorial shows how to connect each individual EigenD instrument to a separate track in Logic Pro so that they can be recorded in an isolated fashion.
This tutorial uses MacOSX Lion and the latest JackOSX beta available for it, which can be downloaded from: http://www.grame.fr/~letz/JackOSX.0.90b4.zip
Any later versions before the official 0.90 release will be announced on the JackOSX Yahoo Group: http://groups.yahoo.com/group/jackosx
This tutorial also uses an external tool called Patchage to easily connect up the audio ports of the Jack system, it can be downloaded from here: http://drobilla.net/software/patchage/
