Hello, I have multiple midi devices that respond properly to PD but ONLY when they are listed as Output Device #1. Any device that gets moved to another # slot ceases to respond. How can I address this? Thank you.

@oscar The first device will be midi channels 1-16, the second device midi channels 17-32........ etc... etc.
Pd makes a sort of "aggregate device".
Does that make sense? .... and solve your problem?
David.

Yes it did! Thank you.
