The 0HP OR Gate can be used to combine different signals, usually gate or clock signals. The output will give a high voltage whenever a high voltage is present at either of the inputs. This can be useful for combining multiple different gate sources together to trigger the same module, such as using a gate sequencer and a burst generator on a drum module to get drum fills. This module can also process fluctuating voltages, outputting the maximum of the two inputs (the highest of the input voltages above 0). The built in trigger converter outputs a spike whenever the main output transitions from low to high.
This can be purchased as a kit which includes all needed parts and face plate.
