The CLP-50 is a fairly old device (1986). The keyboard has no hammer mechanics and the builtin samples might have been quite good back then, but don't sound that well compared to today's standards. Nonetheless, it has a MIDI output, and in combination with Pianoteq (and after getting used to the keyboard), it plays and sounds pretty good for what it is.
