OR Combiner

OR-combiner for combining triggers and gates. (Not audio or CVs.) It has 4 channels, each with 2 inputs. There is a 3-position ON/OFF/(ON)* switch for each input and one output per channel. (With an LED indicator.) The idea for its invention is that it'll be useful alongside the drum modules which are now all over the market. The circuitry is fully active. It has makeup gain to counteract the diode drop on each input as well as a limiter so that it never outputs more than 10v.
