The Modulator

There are Buchlas, Moogs and Serges, but there is nothing like rolling your own...
Here are my pictures and notes from building an analogue modular synthesizer.

A while ago I planned to buy a Yamaha CS-30 since I wanted to have some kind of simple analogue sequencer device but I couldn't fine one in good condition. Then I moved on looking at the Roland System 100m but figured the price tag for a decent system with sequencer and all would be a bit too high.
Searching the net for analogue sequencers I found the Music From Outer Space 16-step analog sequencer. Quite simple construction and versatile. But an analogue sequencer needs to drive some analog VCOs, and VCOs need VCFs, and VCFs need CV sources, ...
I decided to go for a small basic setup:

MFOS supplies quite nice and high quality PCBs for these designs.
