6-Way Passive OR Combiner
A 2HP 6-way passive-OR module.
Perfect for percussion patches - the output goes high whenever one or more of the inputs goes high - great for routing gates/triggers to different sources or for combining clock signals to create weird polyrhythms.
Be aware that the diodes will reduce any input signal by about 0.7V.
