I am trying to use the bacic functions “Gate” and [xod/core](https://xod.io/libs/xod/core)/pulse-on-change. I have the xod/core@0.37.3 loaded and I get the error Specialization patch not found
Cannot find specialization gate(port) for abstract xod/core/gate.
Try creating the missing patch in your project or install a library which provides such one.

Why don’t you post your project so we can see what you are trying to do? Though it is possible you are using ‘gate’ correctly, it is doubtful. If you really do need a gate for port, you can open the gate(number) node and copy the c++ code to a new gate(port) node. You will need to change the in/out pins to be port instead of number on your new node.
