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.
Ah, lazy of me. @eylvy did a video, posted above, that shows exactly what the differences are. It allows sync to DAW, the ability to adjust the low pass filter of the delay and, among other things, that extra level of plate reverb.
Yeah the main thing is getting access to the big plate reverb setting as well as another dialogue box of controls which I also forget now do what exactly, but which can have a pretty radical impact on the sound. Despite how good it is I haven't used it in a while. The big plate reverb sounds really incredible, if you like big reverb it is worth every penny. Not to mention a nice way to thank the dev for being kind enough to make the free version so full featured.
lunar lander is an incredible app, by far the best plate … and as a whole delay/reverb, a very unique one … worth it, really
