M12 touch application needs iPad with IOS 12, I have same problem as I tried to install to my iPad IOS 11 and unfortunately my iPad cannot be upgraded to IOS 12 due to old type..
I do hope Yamaha can change the application of DTXM M12 touch can be installed in iPad IOS 11 or lower. thanks.
I have the same question. I am going to see if I can download the app on a newer iPad that I am going to borrow from a friend, then go back to my iPad 2 and try and download it via the 'Purchased" section of the app store and see if it will let me download an older version. I'll post back here with my findings.
