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.
Which Looks More Promising To You: AR (Augmented Reality) or VR (Virtual Reality)?
At some point, possibly in the near future, Apple is expected to unveil what is unofficially called "Apple Glasses". These "glasses" are rumored to fit and look like standard eyeglasses or sunglasses and will provide a layer of information on top of reality, making them "augmented reality" glasses. They supposedly will not completely obscure one's view of the surroundings.
On the other side of the spectrum, we have Meta's virtual reality headset which is bulky, can cause tiredness and dizziness and has a limited range.
What is your opinion of where this is all headed?
