Pretty bummed out to open synthesia today and discover that YEARS of data saved has disappeared. All of it. All of my song progress, statistics, recently played, everything. You name it, it's gone. Really sucks because I have thousands of midis on my device. That data helped me identify the songs I want to practice. I really can't tell you just how bad it sucks to have lost all of my data. All of it. Other than that pretty big complaint, I have no complaints.

Fantastic and fun. I've improved so much faster than when I was just watching YouTube tutorials. Was able to easily connect to my keyboards USB midi interface, and it was responsive and quick to display on my phone when I played the keys on the keyboard. Just make sure you have the right USB cables and adapters for your keyboard or else this is probably useless on mobile.

I've learned more songs in my four years of playing piano than with any other music software. But I have a suggestion. For everyone who doesn't have a MIDI keyboard, the app should have a sort of microphone operated sound detection algorithm (or whatever you would call it) which allows for the app to register what sounds come from the piano and show them on the screen via the audio feedback from the microphone. It's a genius idea and I think it will benefit all who don't own a MIDI keyboard.
