People have been complaining about problems using a sustain pedal with the Piano patches BEFORE the last software AND Keylab Mkll hardware revision, yet the problem persists. One recent contributor deemed the Piano V "unusable", as a result. Six months ago (!!!) Arturia finally chimed in and asked if the member inserted the plug into the correct jack. Seriously?! To date, there has been NO response from Arturia on the Forum or via a firmware fix on the Keylab. And now they come out with an updated Casio synth. I just don't understand their priorities. Being an optimist, however, I believe someday they WILL read our posts.
