OK, they don't get much simpler than this! It's a plug that does absolutely nothing but print a stupid message, that I used to use to autoload vst~ so that it didn't keep reporting "vst~ doesn't want midi events" because there was nothing loaded.
I miss Pluggo too :-(
Fwiw, one of the things that stopped me getting into Live/M4L is that Live seems to be the pickiest VST host ever. So many plugs seem to crash Live! Maybe things have improved now, but I never seem to get much further than trying to get the damn thing to run without barfing on my plugs - plugs that worked perfectly well in other hosts,
