Very very cool!

It’s actually not hard to hack this together as a .net application and run it on a laptop, but I suspect your target market has a bit of money to spend.

Learning piano is already largely an upper middle class active and after that what’s another 200$ or 300$.

A higher end digital piano is easily over 2k.

Making sure your target market has money is the key take away.

Not sure if this is in scope, but I’d love an easy way for the community to share midi files. I can somewhat do very basic piano progressions, but I still can’t play well.

I’d be grateful if someone would share midi files for me to plugin to my music software. Of course I’d provide full credit
