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.
Going to the dark side: Mac GarageBand or Logic?
Often, all I want to do is record external audio, and do simple arrangements. I love GarageBand on iOS, but it frustrates me more and more. It stops seeing USB inputs, and it stops playback seemingly at random. In addition, the limit on recording its output, and on copying audio tracks to use elsewhere is driving me nuts.
My solution is to use my old 2010 iMac, which has a brand new SSD and is still going strong. For recording and arranging it will work fine. I will also keep using all my amazing iOS music apps. My process tends to be creating parts of songs in a mix of different apps and hardware, recording the results, arranging, and perhaps re-recording some parts direct into iOS GB. My main gripe is the flaky connectivity between iOS music apps.
I've tried Auria and Cubasis, and find them just as frustrating.
Which brings me to my questions:
For those of you who have moved from (Mac) GB to Logic, what was the essential feature(s) that made you upgrade? For those who use GB on the Mac and are happy with it, why didn't you upgrade? Also, how does Logic Pro X run on old Macs?
