What you're supposed to do is create icons that represent your other hardware - such as a hardware synthesizer or drum machine - and then draw the "lines" to represent the MIDI cables that you have connected between your MIDI hardware unit(s) and your MIDI interface(s), so that you see "Kurzweil K2600", for example, instead of "MIDI port 1", in your sequencing software.
For your "piece of hardware with USB" you can think of it as a "piece of hardware" that's already permanently connected to a USB interface. If you like, you can add a new icon to the "MIDI" side of Audio MIDI setup, name it whatever the piece is actually named, and "draw a line", and it'll show up with whatever name you give it (Drum Machine, Virtual Analog Bleep Bloop Box 2000, whatever), instead of "USB Class Compliant Audio Device" or whatever default name the USB-MIDI port is showing up as now.
thanks for the answer but I think something is still missing.
my "piece of hardware with USB" is actually a Dave Smith TETR4. it is a synthesizer with USB, MIDI IN, MIDI OUT and POLY CHAIN OUT.
in the manual, they say that you just need to plus the USB to edit the synth with the software editor. Whenever I do that, the editor doesn't seem to recognize the synth.
so I thought that I needed to link the synth with my soundcard (with midi) just to make them exchange the data... I guess I had it all wrong somewhere.
too bad the manual for the software editor isn't out yet, I guess I'll have my answers in there...
thanks a lot chrisrnps, and if you can find the answer with the additionnal infos I just gave, go ahead !!
EDIT: and by the way, I already see the "TETRA" thing in the midi setup for osx, it just doesn't want me to link it anywhere... and in the manual they say that you shouldn't plug the USB and the MIDI IN at the same time...
