First of all many thanks for creating the excellent Stage Traxx apps. I have been using Version 2 for many years on my old iPad (iOS 9).
Recently I bought myself an iPad Air 2022 and I found there was Stage Traxx 3! After a quick try-out I was very happy to buy and start using the amazing Stage Traxx 3 - so many fantastic enhancements and new features!
Now I have to find a way to get the audio out to the Mixer/PA. I think this item might solve that problem:
UGREEN USB C to 3.5mm Headphone Jack Type C Aux DAC?
But I would also like to select patches on my external effects using MIDI PC commands. I am thinking this will require some sort of USB hub - would that be correct and is it possible?
EDIT: PS I have a USB-C to MIDI interface already which is working great. I am just looking for a way to have it and audio at the same time.
