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.
Weird Battery Issue (iPhone 6s + AUM + iRig Pro Duo)
I'm not really an iPhone user so I wanted to see if anyone can shed some light on this weird issue: For a particular setup I'm testing, I'm using an iPhone 6s, with an iRig Pro Duo, AUM (with Korg Module and K7D) and a MIDI keyboard.
Both the iRig Pro Duo and the Midi keyboard are powered by their own power adapters.
To connect these items (and charge the iPhone at the same time) I'm using an original Lightning-USB 3 Apple adapter (see picture).
The problem is, the iPhone's battery level goes down DESPITE being on charge, as if it's using more power than what it gets from the power supply (I tried two different ones).
IMPORTANT: the device charges fine if I unplug the iRig Pro Duo and/or if I quit AUM, so we can safely say that the charger and the USB cable (new) are not part of the problem.
Any hints? Thank you for your time.
