This has a pretty powerful 'auto' mode where it grades your practice and steers you towards practicing the bits that you have problems with, it doesn't require you to subscribe to any service or pay (the data is yours and it stays on your computer).

It tracks your progress in a very detailed way and remembers how you played a piece before to help you play it better in the future. It aims at making you independent of the program and to teach you to play well. It still is no substitute for a teacher, but it is certainly better than nothing at all. I have some plans to incorporate all of the Mayron Cole course into it but that will take a long time (and I currently do not have a whole lot of time, but that will change soon).

Music to my ears! I hope more developers go this route and prioritize making quality software over squeezing every available drop of data from users.

I really like this but I can't seem to get my Nanokey2 to work with it.

Edit: Never mind, it was the settings, it set the output to the nanokey, but didn't set the input.

I have synthesia and no, it’s not the same. This one requires you to know sheet music, a must have skill I you want to learn a piece quicker than rote memorization in synthesia. I used to refuse reading sheet music. But, thank goodnesses, I knew I was mistaking and since then was able to learn more complicated pieces like the Aria in Goldberg or couple of preludes in the WTC.

You can actually hide the falling notes and switch to sheet only in Synthesia, this was a much requested feature update made years ago.

This seems more like Flowkey.
