OK, I am just installed the new (4.0.3) firmware to my Mackie MCU Pro and now the faders are moving very, very, very, very smooth, like never before! Now, I am waiting for a move from the Cakewalk side - the problem with not properly functioning "EQ", "Compressor" and "Plug-in" buttons in MCU Pro, by using the SONAR X2 - still remains. Hurry up, gentlemen at Cakewalk!!!
