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.
I just saw the mitosynth got updated to iOS 13 and latest audiobus sei, does it mean that the crackles sound problem when using in audiobus has been solved?
I have an iPad Pro and when using with the iPad native sample rates 48,000 Hz it crackles a lot, if using external audio card with 44,100 it was good.
