USB to Control Voltage Generator Proof of Concept

This is a demonstration of the USB -> CV PC/Analog Synthesizer interface I’m developing.

In this clip, sample data is being sent from Max/MSP over the serial port to a Teensy 2.0 microcontroller. The controller sends the incoming data over an ISP connection to a DAC, the output of which can be used as a modulation source for analog synthesis modules.

4 x 4 Matrix Mixer and State-Variable VCF

I’ve recently built both a 4 x 4 audio matrix mixer and a state-variable vcf. Here are some images:
