keyup & m4l?

    Apr 22 2013 | 7:17 pm there any way to detect the output each time z key is released on the computer keyboard in Ableton?
    I want to create a virtual keyboard with my laptop keyboard...
    the problem is that:
    1) if i have "ΚΕΥ" activated in Ableton(use laptop keyboard as midi input)
    i am obliged to use only few (preselected from Ableton) keys...
    2 )if is not activated(so i can assign all the keys to max4live GUI like live.toggles)
    i have not found the way to detect key-releases as i mentioned..
    3)key/keyup objects they are not working inside Ableton unless you select the device ...
    even if i select the device automatically (via m4l API) key/keyup objects don t work
    thanks in advance
    any new direction would be very helpful!
    (i am windows user so i can t use aka.keyboard)
