Mad crazy super happy with my KeyLab Essential, no problems setting it up with Cubase after a little bit of poking an has really changed the way I work. One problem I am having though is that whenever the KLE49 sends its "yes i'm still here" to Cubase Pro all the sliders and knobs reset to there preset states. I'm sure it's just a setting i've missed somewhere as no one else seems to be having the same problem.
Running Cubase Pro 9.5 and all drives and S/W is uptodate.
Cheers all,
Martin
