This is a synthesizer that uses the keyboard home keys to play around with. There's a lot of code in there to play with - but not much in the way of a UI.
You'll have to build this yourself in Visual Studio or a gnu compiler.
Not much more development planned for this right now; but I'm probably going to just port this to a Raspberry Pi or an Arduino to play with to create a real-time synth computer that can be used with a midi controller (like a cheap keyboard).
