I have a client who has all of the CMC controllers, and none of them work
on windows. I've made sure that he has the latest MIDI drivers for the
controllers, but the MIDI ports don't declare in Cubase (in available MIDI ports, as they should as suggested by setup documentation), and when I try to
add the controllers from the device add menu, they are there, but they
don't add to the devices. He's on windows 7, and he initially had the
controllers on a hub, I got them directly connected and then installed the
drivers, but no luck. The CMC controller software sees the controllers when they're plugged in - they respond, but Cubase just will not connect and talk to them. He's used 6.5 and 7, this is a new windows 7 install. I do not believe that there are too many MIDI drivers installed on the machine (as has been suggested to me from others), so I'm not digging thru the registry to remove extra drivers.
I see no reason why this is not working - these controllers are made by steinberg, they should work with Cubase out of the box. My client's pretty frustrated, since he bought six of these, and none of them will work.
If you have any ideas, I'd be open to them. I'm not sure if it's a chipset
issue, or what not - he is on an HP machine, so I can't see the reason for a USB chipset issue; firewire, yes, USB, no way.
