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.
Why?!!! WHY?!!! In the name of all that is MIDI why don't devs offer relative MIDI mapping?!!!
ARGH! When you're dealing with multiple apps, in software, absolute midi mapping is just about worthless. Especially when you're dealing with encoders.
To date, I've not found a SINGLE iOS app that uses relative midi mapping (i.e. 63/65=-/+ with acceleration).
What kills me is Arturia, in the damn manual for the minilab controller goes to great lengths talking about how relative encoder settings are preferred for DAW/software control, yet THEIR OWN iSEM app doesn't offer it!!
With relative controls you can map the same damn encoders using different midi channels to control basically EVERYTHING with no parameter jumping (the normal "bad thing") or the super annoying," wiggle the s#!t until you find the latch point in pick-up modes...
Seriously, it can't be that hard to do as EVERY DAMN VST and desktop DAW offers relative midi mapping!!!!
