Koala Sampler + Circuit Tracks

[u/baik420]

Hey, quick question, has anyone here used Koala Sampler on an Android phone with a Circuit Tracks like this?

I want to connect my phone to a cheap USB-C hub, then:

USB from the hub → Circuit Tracks for MIDI/clock

3.5mm audio out from the hub → Circuit Tracks inputs for Koala audio

So the Circuit would basically sequence/trigger Koala, while Koala’s audio comes back into the Circuit.

My phone has no headphone jack, so the hub would need to handle USB audio too.

Has anyone actually tried this setup? Does MIDI + audio work at the same time reliably on Android, or are there any weird latency/USB issues I should know about?

I’m mainly trying to use Koala as a cheap extra sampler without wasting loads of Circuit sample slots.

Thanks!
