This VCO uses DG202 (or equivalents) analogue switches to achieve the thru 0 function, based on ideas presented in Electronotes #75.
Note: 20 Jan 2018 - To be clear, the thru-0 mark in the centre of the panel is simply to indicate what type of VCO this is. I have no connection with Antumbra modules which use the same mark on all their panels (and were released a few months after this one).
Available as an assembled Module and as a DIY project.
