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

I’m just putting this here in case anyone wants to know a little about me, since there is no bio or anything like that. You can look at peoples profiles and see what they’ve said in comments etc, but I’ll just put this here. I play drums and I play keyboards. I like everything from Hammond, Piano, to different Synths, etc. I’ve tried other instruments, I can play other instruments, but drums and keyboards are what I really do. I’ve been playing drums for close to 20 years (not very active on drums the last 7 years) and keyboards for 15 years off and on. I got my first electronic devices with sequencers in 2014 with the original 3 Korg Volcas, I got my first iPhone in 2015 and the first thing I did was get a MIDI interface for it, iPad in 2016 and I’ve been using iOS for all of my computer based music ever since getting the iPad.
