Yes its called Rewire. It was first seen in Rebirth by Propellerheads. Now it is found in most popular audio programs. Its used to connect audio through different applications.

External signal routing will be like the mac via a software mixer that comes with your audio interface.

both programs need to support reWire for it to work... i

the signal routing is mainly from stand alone software (that don't support rewire) that is running inside my computer that i need to route to my multi-tracking.

when i ran soundflower it showed up as an input/output along with my motu inputs/outputs...

i found it!!!!!

Now I understand, you want to connect standalone and non-rewire apps to your multitrack program. Thanks for sharing that link I didn't know there was a way to do this.
