That, my friends, is a Digital Synthesizer that I created from scratch. If you'd like more information regarding it, let me know. Sorry that took so long, Otaku. :P
I have a lot of respect for people who do Electrical Eng and/or get wtf circuits are about. When I did aerospace eng that stuff flew past my understanding in the first 5min of the lecture.
Only inside the IC's. It was mostly 556 timers, 741 Operational Amps, and a 348 audio Amp. The rest of it is just a fuckton of .1uF caps and resistors (and the blue cubes are variable 100k resistors.)
