In the works

I've got a couple new projects in the works. One is tentatively titled the Filter Modulator, a low-pass filter modulated by an LFO's pulse or triangle wave with adjustable pulse width. The other is an Amplitude Modulator, and performs tremolo as well as audio-range AM (similar sound to ring modulation) using an oscillator again with pulse or triangle wave with adjustable pulse width.

I'm making a PCB for the Filter Modulator right now... here's a sneak peak:
