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.

No sound via an audio interface on the iPad when loop playback starts
I would like to use Loopy Pro on the iPad with the help of a Bluetooth MIDI controller as a looper on the go.
The audio interface is a headphone amplifier connected directly to the guitar and my iPad.
I have set everything up successfully so far.
The only problem is that the loop starts without sound.
Only when I stop the loop and then start it again is the sound there.
Is there any option I need to change? I haven't found anything yet.
My setup:
- Electric guitar
- Fender Mustang Micro headphone amplifier with audio interface
- iPadOS 17
- BOSS FS-1-WL MIDI controller via Bluetooth
Comments
As I read the manual, the USB-C audio interface is input-only. Audio output is over Bluetooth. You may need to configure Loopy Pro explicitly to output over BT.
Thank you. I hadn't thought about the instructions for the interface.
Is there a setting somewhere in Loopy Pro that allows this?
I can't find anything so far after a long search.
Everything is set correctly on the iPad. Audio output via Bluetooth.

You are likely to experience a lot of latency if you are sending audio out via Bluetooth .
OP has indicated that audio out is happening, correct? If you record a loop , stop and play it back, it plays correctly? If so, it doesn’t sound like routing is the issue.
Post screenshots of all your settings.
Also , if you don’t use your interface, does it work as you expect?
Also, make sure that you are using the latest version from the App Store.
Okay. I've now got around to taking the screenshots and the connections.
I don't notice any latency via the Bluetooth playback.
The audio output works.
If I stop the recorded loop and then start it again, I have sound.
Unfortunately, playback does not work straight away.
If I don't use the interface and record with the built-in iPad microphone, it works as intended.
If I switch on multi-route audio in the system settings, playback via the iPad speakers also works immediately. Only via Bluetooth is the sound only played back after I stop and restart the loop.
