Doh!
Looks like this particular feature is still in development and won't be included in the new Hopkinton release. They've also changed the title of this feature from "Track-to-Track Routing" to "Virtual Patch Points", so while the ability to print to a new track/record virtual synths is on the way, I think the jury's still out on whether this will function as an Aux track (thereby allowing bus-like behavior for grouping tracks, parallel processing, etc. within the track pane). Then again, they've broken out "Synth Recording" as a separate feature, so who knows.
I'm so impatient!!!!
