yes i did use the comma correctly...
by 'use multiple devices correctly' i am unsure exactly what you mean... in my dialog box there are four devices for midi in and 4 devices for midi out... i assume this means i am using multiple devices correctly as when i first loaded pd there was only one space for each...
'did you use channels correctly'... my feeling is that this is where the problem is... i played around with that a little, but didnt really get very far... do i need to use two seperate midi out objects in the window each running a different channel?

did you try "-midioutdev 1,2" ? (the comma is the important thing)

i don't think that "-midioutdev 1 -midioutdev 2" will do what you want.

ok, this seems to be more serious then
i guess, you are sure you tried "use multiple devices"...

probably run 2 pd's, each with a single midi-device.

ah, and are you sure that you try to output correctly ?
you have to use channels 17-32 for the second midi-device.
