I'm having a hard time enabling after touch on the laboratory 61 key. I try to enable it, and even modify its values but nothing happens. I first hit the setup button on the keyboard >then I go to the after touch controls and set the mode to control >I then try to set it to a midi channel, but no matter what channel I set it to, it still goes back to channel one. > From there on I can't adjust ANY value no matter whether I turn the knob or not. This is very frustrating as one of the main reasons I bought the laboratory hybrid synthesizer is because it had after touch otherwise it is a fine midi controller.
