Ashley Elsdon from Palm Sounds accidentally let slip that Audiobus will be releasing at the end of this month! Over on the Audiobus Forum, Sebastian Dittmann confirmed that March 27th is the official release date!
Update: On Saturday morning the Audiobus team modified their release date to March 27, "+ maybe 1 or 2 days for the media to calm down about Gadget again. I'll announce the actual day as soon as we decide it for sure." Since Gadget was delayed to late March, they want to give that some space.
Audiobus 3 features three key factors to propel the platform forward, while also greatly improving the workflow of connecting multiple apps.
Since early 2012 we've been fortunate enough to have many developers agreeing on OMAC as a standard for Virtual MIDI. This has enabled us to do a lot of amazing stuff, and opened up new opportunities for sequencer apps. Entirely app-based studios became possible! Unfortunately none of that has ever been very sane to manage. 5 years later and life is about to get a lot easier!
Audiobus 3 includes a new way to route MIDI between apps, using a similar interface to the one pioneered by the original Audiobus. Simply select your input app and tell it where you want it to go. Finally MIDI between apps can have a consistent and logical routing procedure, instead of the archaic trail-and-error we've all had to experience a hundred times over.
As you see in the screenshot above, multiple tracks from Fugue Machine are being routed out to other apps on their own lanes. Having discrete lanes opens up a whole new world of possibilities on iOS! For the first time ever we can begin to use MIDI effects between apps! This sort of feature is popular on desktop DAWs, and allows for all kinds of interesting trickery; like scale-locking, and dynamic key-remapping. You can see one such app is active in the MIDI Effect Slots of the two right lanes. This is an entirely new class of apps on iOS!
AudioUnit v3 Support
This screenshot also reveals two instances of Phasemaker are in play! Audiobus 3 can act as an AU host, allowing for multiple instances of any AUv3 app. We've all experienced a lot of problems with Inter-app Audio over the years, but I think Apple nailed it with AUv3. Now we can have AUv3 with the convenience of Audiobus!
Hosting all of the routing platforms available in Audiobus 3 will be a lot easier now with an integrated mixer. Instead of diving into every single app to tweak their master volume, you can easily change individual app volumes from inside of Audiobus!
And all of this will be available in just 10 days! No more vague "coming soon" here, we have a release date!
