Hello Peter and everybody else who might stumble upon this!

I'm writing this on behalf of my uncle, who has been using Stage Traxx for many years (and is a huge fan of the app) but doesn't speak English very well. He is looking for an answer to a specific setup-question and I offered to ask here on the forum if anyone can possibly assist.

My uncle is currently using the following setup with Stage Traxx: his iPad is connected to a "Lightning -> USB + Lightning" adapter. The USB cable goes into his mixing desk and the Lightning cable charges the iPad (with this mixing desk he needs to use a USB connection because the audio quality of the backing tracks is noticeably worse when he uses the headphone jack).
The above setup works brilliantly, but he would also like to be able to add an external monitor via HDMI (for Karaoke-like situations and occasions where there are several singers who need to see the song lyrics).
Trying to make this work he purchased an adapter offering "Lightning -> HDMI + USB + Lightning" and tried to connect the monitor to HDMI, the mixing desk to USB and the charger to Lightning. This does not work however, as the HDMI connection automatically "grabs" the audio and there is no audio going into the mixing desk.
Granted, those adapters are probably not meant to be used like that - and hence are not capable of "splitting" audio and video so that the audio would be available to the mixing desk via USB. But before giving up on the idea entirely we wanted to ask if Peter or someone here in the forum maybe knows about an adapter (or a different solution) to achieve this setup.

TLDR: does anyone happen to know of a way to grab the screen/lyrics from the iPad via HDMI while simultaneously grabbing the audio via USB? If so, we would love to know 🙂

Thanks for reading and cheers from Austria,
Anna
