A silly little keyboard-driven software organ that I wrote to entertain my newborn daughter. It's named for her (Rosalee).
See the source code for license details. There's more than one because I borrowed some code.
You can try this on the web here.
For local testing, install Gio's dependencies and then run:
go run git.sr.ht/~whereswaldon/chipalee@latest
I welcome improvements if you feel motivated to implement them. Send signed-off patches to my public inbox.
