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.

Audiobus is the app that makes the rest of your setup better.

MF Splitter fails launching

Hi, I bought whole midiflow package for my iPad. Yesterday, Midiflow splitter stopped working suddenly. I can't understand what is happening.

In the midi setup view of Airbus 3 I can add MF Splitter as an effect, but the icon shows it keeps attempting to launch, but never does.

I'm using a 6th Gen iPad with IOS 17.0.3 - 128 GB.
It's a huge problem because I have been working in a complex setup for live playing of many songs.

S.O.S Thanks!


  • I found that if I closing Audiobus and opening again it works, but I'm really annoyed about stability when in Live. Checking the memory seems not the problem. Any tip to avoid this sudden communication problems between Audiobus and MF Splitter?

  • You could try starting MF Splitter first, before starting Audiobus. That sometimes works better for IAAs.
