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.
Apogee One stopped working with Mac OS 10.13.6
My Apogee One is no longer recognized by my iMac. In GarageBand I get a pop-up message saying, " The last selected audio interface is not available." Also the lights for mic, headphones, and guitar input on the Apogee One are flashing on and off. It is plugged into direct power from an electrical outlet. I'm not running it off of batteries. It has new batteries in it. I've been recording with this Apogee One microphone for at least 3 years and nearly one year on my new iMac with no problems. I recently updated the Mac OS to 10.13.6.
In the Mac system preferences under Sound Input, the Apogee One source was coming and going in the list. In fact as I was typing this it appeared for about a second and disappeared.
I have not installed any new drivers from Apogee. When I got my new iMac last January I didn't have to. It just worked when I plugged it in. Is there a new driver needed for the Apogee One?
