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.
Workflow tip: recording automation in GarageBand with Enso (secret weapon!!)
Here is how I use Enso and record cool automation stuff in GarageBand 😎 :
[EDIT]A very short video just to show how it works and how fast it can be:[/EDIT]
Set Enso like this (create some presets with various bars numbers), set the numbers of bars you need (for long recordings, set long memory ON, I was able to record 64 bars since iOS13 update). Tap on left red circled record button. If only play button is visible, tap erase cross button, then play and stop GB, tap rewind (all shown by yellow arrows) and Enso left record button should be displayed.
Then open your effect window, tap GB play button and have fun with knobs creating some cool sound movement. After the numbers of bars you have defined is reached, Enso record will stop.
Then tap Enso buffer save button, set a new name and select/copy this name. Select GarageBand File Transfer folder and tap save.
Explore GarageBand loops and paste Enso loop name in search box, this will helps you find it quickly.
Then drag that loop to GarageBand arrangement or loops session view and you’re done.
I’ve successfully used this with multiple Enso instances so that can be used for making stems too (allow also to avoid GB built-in limiter on individual tracks export).
Note: that it will not work properly with some built-in GB instruments like bass or guitar, so use GB merge feature on those tracks before using Enso on their audio rendered tracks. This is because those instruments don’t use main sample rate, same issue with 4pockets Multitrack effect.
