[PD] os x and internal midi devices?

[Chris Madak]

hello-

so...i've been using pd 0.37 in os x, and trying to send midi to 
"notein" from steim's "junXion" application, which maps input from usb 
game controllers to midi control.  the problem is that, whereas all 
other midi-related software i've used automatically recognizes "junXion 
port 1" as an input when the program is running, "-listdev" doesn't 
come up with anything, and thus, i've been unable to get any sort of 
midi input at all, because i have no idea how to set the "-mididev" 
flags, or whether there's a larger problem at work.
any thoughts/advice?  would this have anything to do with junXion being 
an internal (software) device?

thanks,

chris
