Pianizator: donate edition

The already familiar Pianizator. Previously, it was a paid version for those who wanted to support the project. But now this application is distributed for free due to weather conditions on the planet. And so, here everything is like in the regular version. Simple fragments of famous tunes, step-by-step demonstration with one finger. You can use this version as a stable backup, if you are a connoisseur. It will be updated a little later than the main one.
