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.
Metropolis / Spidericemidas + Tardigrain
There are so many wonderful synths and FX. For a beginner it must be a virtual haystack of needles. It almost seems unfair to all the devs that we don’t or can’t take advantage of their creations regularly. So it is for me and Tardigrain. Yet, here it is, along with a great new KAULDRON preset from @Spidericemidas.
Add to that Ravenscroft 275 and BeatHawk total Bass and you have a romantic re-envisioning of Fritz Lang’s Metropolis.
