It appears that the maximum number of inlets/outlets I can create in a user module is limited to 100, is this correct?

I don't think so, normally it's unlimited.

I think there may be a problem somewhere then as I can only get params 0-99 even if I set the number of params to >100. I have tried this the normal way and the Test Query way and cannot get >100 params.

I think I understand,
if the number of in/outlets is >100 you have to use the scroller in the module panel, to display them in the patch.
This avoid 68909879 pixels height modules in the patch window...

Oops, you are correct. I did not realise the scroller in the module panel also scrolls the module params in that patch window. After all this time I still discover new things in Usine every day
