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.
New iPhone Pro (w/o headphone jack) and a USB battery powered rig
I got a new iPhone without the headphone jack and wanted to use a Powered USB hub to connect:
- A USB bus power Audio Interface with a headphone jack
- A USB MIDI keyboard controller
- A USB Guitar audio interface (optional to allow more audio in's on the audio interface like Mic's)
I wanted to power the whole "USB Network" of devices with a battery so I bought one of the new
Battery Units that outputs a port of 18W 5V.
My USB hub would only work with a wall power adapter but today a 5V barrel adapter showed up that brings the Hub up off the single 18W power port on the new battery and everything connected to the hub lit up.
Finally audio in/out with headphones and MIDI controllers (the HUB has 8 USB ports).
Everything I connect is visible in AUM and not a single connect to wall power.
Now how long will the 18W battery drive the whole rig... it's rated at 20,000 mAH.
