It has a JCM900(in) and JCM900(out)…
It doesn’t need to be in two separate mappings. I downloaded and tested it, and it turns out Podium fails to recognize it as an insert plugin because its mono in AND mono out. Release 1.66 will import it as an insert plugin.
You can convert the two global mappings into one insert mappings like this:
Enter the properties dialog for one of the mappings, remove the in/out from the name, uncheck the global instance option, set ‘mono’ in both source and target combo boxes. Delete the other mapping.
If it was necessary to use it as a global plugin, then you would set it up like you described.
