Final Project Progress

I've been waiting on a bunch of parts still, so I have yet to tackle the white noise generator, but I'm very close to getting my oscillators working. However, I just can't get pressure on the piezo to translate into any change in volume of the oscillator. I think I need to solder some leads to the piezos or something because they might not be connecting into the breadboard correctly. I also need to start thinking about how I want to enclose my project. The bowls and knobs need to be visible, so I'm just going to have to spend some time figuring out that whole set up.

Here's a picture of my oscillator as is. I was planning on putting a high and low pass filter on each of these oscillators, but the priority right now is getting the piezos to work.
