myPiano app from youtube lesson

Hi!
Please, where do I can find myPiano app starter file whose description would have been appeared in a youtube lesson of about 1 week ago?

Is this what you are searching for Donato? https://sites.google.com/site/oshersappinventor/piano
or something else?

This is Osher’s …

Regards,
Steve

It seems more complex of that I was looking for.
Anyway the tutors have been provided with the link to the template.
Thank You.
