I use this (and the sister web app typeatap) with my pre-school niece. She loves composing music from keyboard letters and has really learned where the letters are on a qwerty keyboard faster than any other option for someone that age. There is seriously some untapped educational potential here. Or maybe it's just forming bad habits.
May I ask where can we find the "sister web app typeatap"? I'm slowly introducing my 3.5 yo daughter with the keyboard. She can pronounce letters from A to Z, and write them on paper in upper case. I'd love to hear about more educational app like this!
Enjoyed playing with it. It would be nice to see some WebMIDI support so it can be triggered with a MIDI keyboard.
On the same topic, I found Google's Oboe project really interesting. It's a C++ library for audio that works on both Chrome (via WASM) and Android (with AAudio). This talk from Google I/O 2019 gave a demo/walkthrough: https://www.youtube.com/watch?v=-GaD0RCp-Q0
