This is a version of https://github.com/elisehuard/wonky_music reimagined using Mikka. The basic music playing is the same but it does things a little differently with regards to message passing and I also changed it so the Conductor interacts with a Band of Instruments. It should behave the same way as the original.
It is a really fun demo with sound :)
You must install the mikka gem...
jruby --1.9 play
