I've been sitting on this for nearly 2 months now, and I can finally talk about it! Audiobus is amazing for its ability to link the audio-streams of different apps and devices, allowing for completely new routing. What really blew my mind though is the fact that it can do all of this with discrete ports from the same app!

Pictured here is a beta version of Loopy that accepts these different port connections. There are a lot of possibilities here with "Studio" apps as well! Mix Animoog on track 1, Arctic on Track 2, and each drum from MoDrum on its own track. Now you can pan and apply effects to the individual tracks/ports, instead of a global reverb on everything!

With discrete ports you can run each individual instrument and then mix them in ways that won't drown each other out; a challenge faced by everyone who loves to use Genome for sequencing multiple apps together. No more cramming everything out of your headphone jack and hoping for the best!

This has been a key factor missing in iOS Music Apps and really elevates the platform into Pro Audio territory.
