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.

The problem is that most of the audio stuff only works in a specific browsers. Even though Safari and Chrome were build from the same common ground, a lot of audio stuff just doesn't work in both. And let's not even begin about Firefox, Edge and Opera... The most fun audio stuff was made in Flash which was cross browser and cross platform, is dead. But Flash is dead...
