Audiobus 3 was updated with support for the latest Ableton Link revision, which adds Start/Stop Sync. Previously Ableton Link could only tempo sync devices and apps, but version 3 now adds Start and Stop commands. Audiobus' implementation makes it possible for apps to take advantage of this without actually integrating the latest Ableton Link SDK themselves.
The new Audiobus SDK came with the following note:
The new version of Audiobus 3, will forward Link Start Stop Sync state changes in the form of Audiobus triggers. If you've implemented a play toggle Audiobus trigger, your app will be started or stopped in time with Link automatically.
This is a clever use of existing tech to quickly leverage new tech!
