/*
This code contains three sections, the first defines the synthdef. 
The second starts up the synth and the GUI for playing with the presets live.
The third is used to render out the completed album version of the song.

The song can be downloaded as part of the free compilation 'Far, Far Away', released by Waxen Wings. 
http://waxenwings.bandcamp.com/album/far-far-away

I have written a blog post detailing the code and the revisions it went through
