WHY WON'T IT WORK?

This is the post that I wanted to put up last night, but, due to Youtube being useless, it's had to wait until today.

Anyway, having spent a while checking out every schematic on Tim Escobedo's site, I decided to have a go at messing around with the PWM, which turned out to be masses of fun. At the moment, it has an envelope which controls both the speed and depth of a tremolo simultaneously. The tremolo, in turn, is controlling the pulse width.

Confused? so am I, here's a video of what  I've got so far:

Ok, so when I make something, I almost expect it not to work, but when I'm using technology that's been proven over years of use, and even that fails me, it's just annoying. This is the first video I tried to upload to Youtube, it's supposed to be a demonstration of my version of Tim Escobedo's VCF fuzz pedal, with some additions.

This is how it appears on the website:





I feel that the lack of audio makes it slightly less interesting...
