I'm not trying to be cynical but what is special about this verses that 1000s of similar sites that came before? Here's one of google's https://www.google.com/logos/2017/fischinger/fischinger17.ht... Here's Ableton's https://learningmusic.ableton.com/ Is there something special about this one?
I too feel a little cynical, because I built basically exactly this back in 2012. Before Google, and before Ableton. AFAIK, it was the first grid sequencer online. The first version used the Mozilla audio API, before Web Audio was even a thing. I wish I was credited for the inspiration somewhere, but I guess it's very possible that this is an independent reinvention. I called it MusicToy: http://maximecb.github.io/Mu…
