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.
The more things change....
I stopped using my iPhone studio when Apple took away the headphone jack. I held on for as long as I could, but eventually had to upgrade. Without both the Lightning connector and the separate headphone jack I was dead in the water. Bluetooth (at the time) had way too much latency. I've recently gotten interested again, but am finding that so much has changed that nothing I used to do seems to work. I upgraded to AB3, but my core apps (iReal Pro, MultiTrack DAW, AUFX, AudioReverb) just don't seem to want to play nice. Rather than going through the brambles of trying to debug all of this (which seems a little pointless since I still can't use my original hardware setup) I thought I'd ask if perhaps there have been major changes in the last, say, five years that make it necessary or advisable to start from scratch. What I want to do is play backing tracks (iReal Pro,) play my horn through a mic (originally a Tascam stereo mic that plugged into the Lightning connector,) run the horn through effects, and then send all that to MultiTrack DAW to record while monitoring through headphones.
Has Apple somehow made all this obsolete in an effort to protect Garage Band? I notice that AUFX hasn't updated in over two years. Have the developers that I used simply dropped out? (I know that Multitrack DAW is still current and active.) Why does opening up one of my old saved presets in AB3 seem to stumble so much? Apps don't open. Nothing seems to work together.
I'm running iOS 16 on an iPhone 14, by the way.
What happened in the five years I was asleep?
