Long time customer! I bought one after your original post on HN. Congrats on the milestone. Honestly, it's such a good product and I'm such a bad and inconsistent piano player that I completely forget it exists for months at a time. Then I remember about it, open the app, and everything is there: my attempt to figure out a song, my kids smashing the keys as hard as they can, my cat walking across the keyboard. It's such a joy.
