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.
Inter App Standards
One of my biggest pet peeves is that not all interapp audio synths or sound modules are easy to record with via midi.
Some open up as an instrument in a DAW, while others have to be opened as an input on an audio channel to show up, like Korg Module, Roland Sound Canvas and Geoshred.
I'm starting to think everything should just be an audio unit and function like a VST. Or....can't we just have VSTs? Would it be that difficult? it's also weird for me that 3rd party apps all exist outside of the DAW instead of inside the DAW, like VSTs do.
It also seems like, even though Apple has the only platform worth writing music making apps for, that they would cater to this slice of users a bit more, rather than think of it as a novelty group of users that don't seem to matter to them that much....yet. I'm thinking as this group grows and more people come on board, Apple might realize we might eventually make up a substantial part of the overall IOS users community, but for now it seems like we are an afterthought.
I feel sorry for the developers that have to completely rewrite their code at times when Apple comes out with a new version of their operating system. So none of these things are going to stop me...I'll always find a work around, but sometimes I spend an hour or more on a workaround when I could be making music. That's the most frustrating part for me.
