Thanks for posting pics, everything looks set up well!
Sorry for my previous reply (now deleted), totally misunderstood and inaccurate.
You can have a whole bunch of different midi tracks sending info to your organelle at once, but it sounds like you don’t really want that in this scenario. If you want to automate knob movements too - you can, using cc# 21, 22, 23 and 24.
If you find later you want to automate a whole heap of different parameters - you can do that too with the orac patch and using it’s ‘midi learn’ function to control the many various orac ‘modules’.
As far as bouncing to audio only - i would always encourage it. If you are trying to write and record music you will work wayyyy faster if you do this frequently.
You are able to have as many tracks of separately recorded organelle audio as you like.
Same goes for midi, it’s just more complicated to use unfortunately. It’d be worth having a look at logic’s documentation on using external instruments for some extra midi tips
