hi does anybody know if its possible to use to dmx-usb devices parallel (one for in - one for out) in general? and of course in pd?
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.
yes -- the entec one if i am right -- and your externals -- and windows (which always seems to limit possibilities)
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 dont think i will really need more than 12 in channels...
I tried to receive 12 DMX channels and send 512 channels at the same time using two interfaces and it worked.
thanks... that cleared up a lot..
