JACK Aware

Any program that supports JACK is said to be JACK Aware. This means that it not only has support for JACK audio and MIDI ports, but that is also is capable of having it's timeline synced up via JACK. 
 
The combination of these two allow for modular set ups where programs can be interconnected, as well as being kept in sync.
