An experimental drum machine UI derived from the hooks-drum-machine used to experiment with a few different Arez and React4j features. The source code has been vendored into this repository and is available at vendor/hooks-drum-machine.
The site has been deployed to https://react4j.github.io/drumloop/drumloop/. The solution can also be run through the GWT DevServer and is available at http://127.0.0.1:8888/drumloop_dev/ but it is assumed that you know enough about Buildr/GWT/etc to get yourself to a running DevServer.
