Dod envelope filter 440, HELP!
.......i've been trying to make this friggin thing for almost a year and i can never get it , the closest i get is a light controlled sound...the more the light the the higher the pitch...also i have gotten it to where when i play it will distort to an extent, neither pots do anything audible and the led doesn't light up...i am 99% sure ive got most of the circuit right and i know i've got the ic hooked up right...can someone please help? or even better yet (i know its asking alot but...) make a pcb for me?  
 
 
THANK YOU SO MUCH!
