So I've sorted out sending 16 channels of midi from OM to Logic through an IAC bus.

I'm now ready to build a bigger template.

I've created 4 OM ports in IAC: OM-1, OM-2, OM-3, OM-4.

How do I access these ports in tracks in Logic and assign them to these additional ports and 16 midi channels each?

Do I need to go in and wire up the Environment? Yikes!

Thanks for any help!

You need to find this in the Logic manual.
