I have a Mackie Control Universal but I had problems with it when it was plugged into my set-up. I found sometimes the faders would move by themselves even though there was no automation. I could move the master fader up to increase the volume and find that on the next bar it would slide back down to where it was previously.
I remain convinced though that this is something to do with my FireFace 800, despite RME denying it.
I need to spend a day or so sorting this out because other than this it is a great unit - bit frustrating at first as with a mouse you have access to alsorts. Whereas with just 8 sliders and 8 pots available to control all the usual Cubase 4 (in my case) parameters the accustomisation process can be very daunting.
I cannot comment on the other controller you mentioned as for Ten'[s suggestion - I can't tell if he serious or not
