Hi there,
I think this might be a Red Herring, or at least half of one, after all.
So my original set-up/use case was where I was able to power the Reloop using a USB-C to USB-A into a USB power hub, and then use a USB-C to USB-C with USB-A adapter into my laptop for Djay Pro on Windows - without issue.
However, when I then attempted to power the Reloop in the same way and then use the same USB-C cable (this time without the USB-A adapter to go into the iPad Air) it would not work. I could power the Reloop, but I would not be able to get any connection or go into Hardware mode on the right (Data) port into the iPad.
But if I removed the power cable and switched the USB-C to the left port I could connect in Hardware Mode, but then I would be powering the Reloop using the iPad’s battery. This is where I reported the problem originally.
However, after some more experimentation last night it seems that if I use a USB-C to USB-C power cable to a USB-C charger (which only arrived yesterday) instead of the USB-C to USB-A to power bank, not only do I get power to the Reloop, but also as if by magic the other USB-C cable on the data port to the iPad then kicks into life and Hardware Mode would engage.
Very strange, but it works and would be the standard set-up going forward. The only reason why I tested it the previous way was purely because the USB-C to USB-C cable for power wasn’t quite long enough, so I just tried to the use the “existing” power solution, that provided by the USB-C to USB-A to the power bank, which had apparently worked without issue with the Windows setup.
So… very strange, but just in case it catches anyone else out, I thought I would report back my findings.
To clarify, I am not using any real “workaround” - this is standard, but if anything it just seems that either the Reloop Mixtour Pro or Djay iOS is fussy about not going into Hardware Mode without having a full USB-C end-to-end solution. Even if the USB-C to USB-A cable I was trying to use for power didn’t fully support Power Delivery to power the iPad, I still don’t understand why the iPad wouldn’t accept a Hardware Mode connection on the Data port, just without charging capability. Oh well, never mind!
Cheers,
James
