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.
moodscaper caf files
Since .caf files appear to be only readable by quicktime, is there a way to open them in ios/ipados and convert them there? if Apple wants to have a proprietary format, great, but there should be a way to use them.
if it can't be done, then perhaps the moodscaper dev would consider changing the file formats to something more usable on ios/ipados (since moodscaper IS an ios/ipados app)?
i'm going back to the moodscaper manual to see whether the files you create yourself will be stored as .wav files.
