Love the software but need it to work on my new iPad

To developer: You can easily use this software with a MIDI Bluetooth device. I use PianoDisc. I have recently purchased a new iPad that is being used explicitly with the PianoDisc system and a Yamaha MIDI piano. I am having trouble transferring the software purchase from my old iPad to my new one. My initial try was to use family sharing to restore my purchase. I cannot get this to work. Please indicate how I can transfer the software purchase of pro over to my new iPad. Thank you for your assistance with this.

Restoring purchases problem resolved!

Absolutely a wonderful app, with continued support for so many years! Thank you to the developer, keep up the good work!

So to everyone with the complaint that their phone isn’t restoring the purchase because they can’t find the settings button, I had the same problem. Here’s the solution, just flip your phone to landscape mode and two more buttons appear, “help” and “settings”.
In the settings there is a a lot more functions that can be tweaked, one of them is restoring your purchase.

Doesn’t work on iPhone

A friend told me about the app so I downloaded it to my phone and tried repeatedly to upgrade to the pay version so I could play my entire midi files but could not find a way to get it done. I finally tried it on my iPad and found out the problem was that the settings button does not display on my phone. I paid for the full version and downloaded all my files. I went back to my phone hoping everything would be there because my iPad and phone are on the same account. But nothing was there and my phone still had the free version. I opened and closed the app and even redownloaded it so it would reset and transferred all my files but had to do them manually. I finally got a link to upgrade to the paid version but was expected to pay a second time so I declined.
