I have spent weeks recently working on a little side project converting MIDIs to colored children’s piano sheet music. I am most of the way there but have been dragging my feet on building the web ui specifically because I was unsure how to render the notes in a flexible way that could look good on multiple devices. This looks like it could be a good jumping off point, and I fully intend to give it a try.

My daughter absolutely loves my Little Tikes piano from the 1980s but all the sheet music I find online, even for the newer Little Tikes pianos, have different colors associated with notes. I have built up a small library of simple MIDIs, and my intent is to have some preset toy pianos to choose from or let the end user specify colors-to-notes manually.
