Yes and no. - Depends on which DMX USB devices you're talking about,
which OS and whether a Pd object exists for it at all.
The answer is yes if you're using the Open DMX USB Interface together
with my Pd externals. But: input in general is not working that good
because the hardware receive buffer on the interface is too small to
hold a full 512 channel DMX message. So when trying to receive a lot of
DMX channels you'll get wrong input or just an error message and no
input at all. I tried to receive 12 DMX channels and send 512 channels
at the same time using two interfaces and it worked.
