Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Question about App backup with iMazing
One of my (non-music) apps has announced an update that will change (i.e. nerf) some well-loved features. I think this update has already rolled out though I update all my apps manually and haven't installed it.
Other threads have mentioned how iMazing can be used to backup an existing version of an app so it can be restored if needed.
Before spending money on iMazing, I hope to clarify how this works, as the App Store version is now updated from the version I want to keep.
Can I use iMazing to take a backup of the app as it is currently installed on my iPad, and then reinstate that version of the app if needed, or would I need to have downloaded it from the App Store and backed it up before the new version was released?
