I know a lot of us were bummed when the SRC Transfer app for iPhone and iPad stopped working with newer versions of iOS… but apparently whatever compatibility issues there were in iOS have been resolved because I just reinstalled the app onto my iPhone and iPad and it actually works! Tested both on iOS 12.4.7 (iPad Air 1) and 13.5 (iPhone 11 Pro).
Combined with the big update from today, my iPad is back as a major accessory to the Digitakt!
