I've been using the Arturia for awhile now, and have been just blown away at what it can do!! (especially for its price) I use it as a controller in the studio and as onstage as a main keyboardist I absolutely love the Arturia KeyLab 88. It has an awesome piano-like feel, sensitivity is awesome and the keys seem very quiet compared to most weighted keyboards. Had some difficulty getting the sustain pedal to work correctly, but once I found the proper setting, it's been flawless.
