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.
OT: MacBook Pro for App Development (and Music)
I'm seriously considering getting into iOS app programming as a sideline / hobby. I'm looking for a cost-effective MacBook that will still have a useful service lifetime. I would only be using it lightly for any music production. I just need moderately decent performance, and hopefully to be able to get 3-5 years use out of it.
I've been a mainly a Windows grunt forever, with only light duties supporting MacOS in IT environments. So I know very little about what will work for me or not. This refurb model looked interesting. Any thoughts?
Thanks for your insights!
