Yes, and the integration with Reaper sucks. Getting the knobs to work properly is impossible without dozens of hacks and using OSC.
I tried bitwig studio and was blown away at how seemless and effortless the integration was with the keylab... it was literally "install and go" simplicity.
Its too bad... I invested several weeks getting to know reaper, and was about to buy it. Judging from the various complaints on cockos forums, it looks as though reaper is never going to have descent controller intergration.
