Prototype DIY passive utilities panel


Published on Jan 7, 2014 wellurban·6 videos

"The first parts of my utilities panel are now working: an 8-way CV/audio bus and three passive attenuators...with giant knobs! I'm just using a cardboard panel while I experiment with different passive utilities, but once I've added a whole bunch more, I'll get one made in acrylic or aluminium.

This is just a very simple patch to check that everything's working. One channel of Maths works as a VCO, and goes through a Pittsburgh Filter into DelayLab. The other acts as an LFO, with its output going through the first passive attenuator before hitting the Both in of the VCO channel, thus controlling the amount of modulation. Two fixed voltage sources (mh01 channels) go into the other two attenuators, and thence to LFO frequency and Filter cutoff.

The large knobs make for wiggling heaven (even better when I have two hands free), and the bus keeps the wiggling area free of cables."
