It is a passive OR module. Two channels of 3-input OR logic are provided. The output of channel 2 is internally connected to the input 1 of channel 2 and operates as one OR circuit when it is not patched to input 1 of channel 2.

OR is a circuit that has several input signals and outputs the highest voltage signal among them. If only a negative voltage lower than 0V is input, 0V is output. If this property is used, the gate signal etc.Gate signal patternIt is also useful for making complex envelopes by combining multiple CVs.

Because it is passive (no power consumption), the voltage drops by 0.7V on the output side.
