Audiobus!!!

I was going to blip this a while back, but had another, better, blip. Today I didn't, so here it is: Audiobus!

On the left are a few apps that produce sound (drum machine, synths...); in the middle, an effect processor (in this case JamUp Pro, a great guitar amp and effects sim); and on the right Multitrack, a Digital Audio Workstation (DAW). Until Audiobus there was no way to send audio from one app to another on an iPad; now there is. So instead of being limited to one app at a time, we can have a couple playing, and recording into another, processed through yet another. It's brilliant. Truly game-changing.
