The initial plumbing for giving Way-V a 3rd oscillator and FM capability.
This should truly establish Way-V as the premier Linux synth, it just looks
beastly now...
Implement the 3rd oscillator before I begin experimenting with how the FM
concept will work in practice...  I still have a bug with Osc3 unison to
sort out first...
That fixes the unison bug, now to begin the big FM experiment...
Implement FM into Way-V...  and it's pure magic...  I think my
Linux audio so-called competitors just got pwnd.

Mwahahahahahahahaha!!!!!!
