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.
Korg Module sounds and Korg Gadget sounds (and IAA and AUv3)
Got a new midi keyboard recently with full size keys, larger than I've had in the past, and so I've been having fun playing keyboard with a lot of various app sounds. One thing that struck me with these two Korg behemoths:
Gadget sounds are more interesting to me and, in my opinion, just plain sound better than Module sounds. (I know Module sounds are in Gadget, I'm talking about the ones that aren't.) This surprised me because Module seems positioned as having more "premium" sounds, and has AUv3. The Module sounds are fine, the acoustic pianos are very nice, and the KA Pro strings, sampled E Piano, and the add on organs are extremely high quality; but as soon as I get into anything synthy, digital or analog-emulated, the Gadget instruments just blow Module away, and also seem to blow many individually available apps away that offer similar sounds. The Gadget instruments are shockingly good even compared to some $20-30 standalone synth apps I have!
So this has me torn between which I want to use as a go-to sound module type app (and potentially invest more IAP in). I love AUM, and primarily use AUM when playing music on iPad. In the past I've leaned toward AUv3 apps, because that's what AUM is about after all right? But in practice, is the only difference between AUv3 and IAA in AUM that the screen will temporarily change if I want to adjust something in Gadget? I can still use all the routing features of AUM with Gadget (or any other IAA app)? Is the only difference really that there is no mini window designed to work in AUM or a similar hub? IAA doesn't seem like a huge deterrent from use then, at least for how I'm using it (like a keyboard sound module).
