The custom plants weren’t be seen because of the spaces in front of them. Big fail on my part. It was a current working directory issue that was messing up the including of files in Csound. It seems that including more than one custom plant in a plant is causing issues. I can’t run off a build now as I’m not at my OSX machine, but I’ll get one to you tomorrow. Probably best I fix the number of plants allowed in a plant first.
