From what I can tell, Logic 9 doesn't include anything like this, in the traditional sense anyway. It appears that we have to create our own in the environments mode. Is there a good source where people have collected some useful setups in this? It seems like it's a lot of work to make anything close to the usual midi plugins you'd come across. Of course, correct me if I'm wrong because this is an issue that makes me hesitant to jump to L9.
