Not to create any east/west battles here but I subscribe to a board for DIY electronic and the subject of the Buchla Dual Voltage Control Processor came up.

This is a strange little beast. This allows two control voltages to definte a single control votage ourput:

When you read about it you can see what a stange beast it is but It looks to it’s screaming to be made into a fooger and would provide some incredible power to the fooger line putting foogers up there with modulars.
Just a thought…
