I think Gimp also allows control via MIDI input. Never tried it though.

Yes, there is a Gimp build that allows you to change colors via MIDI. One thing I didn't like about the built I tested was that you can't change colors while! making a stroke.

I love it! Really cool idea and execution! I would love to experiment using a ball as the selector.

My current strategy for binding automation is using my razer naga and binding all those buttons to do various actions depending on the app that's up.

With midi data being 7-bit aren't you losing out on an awful lot of the available colour space? Or is it near enough to not really matter in this case?

You lose half of the possible steps in RGB mode (128 instead of 256), but a change of 2 is hardly noticeable when painting, even when applied to all three channels.

Really neat! Shame it's Chromium only, though. Does Firefox intend to implement web MIDI eventually? I'm using MIDI as an input to the control software for an art installation at the moment, and once WebGPU is out and compute shaders are available on the web, the whole thing could be deployed to the browser, which would be cool. At the moment it's built to a native executable, which is fast, but not as easy to share.

Mozilla for now has been against WebMIDI due to concerns about the scope and security implications: https://github.com/mozilla/standards-positions/issues/58

Found a cool similar drawing example app: etchasketch.fun (Yup, lets you draw on a Etch-a-sketch with MIDI knobs)

Needs an SSL update, otherwise it won't work in newer chrome versions.

The MIDI web APIs aren't HTTPS-only, so you can just use HTTP (site doesn't redirect)
