I routinely use a little Phillips CDR765 to make CD's directly from the KN5000. I first record into the sequencer and then play the sequenced song during the recording. I just connect the audio output from the keyboard directly to the recorder to do the recording. There are several limitations but I am satisfied with the results. It is easiest if velocity levels for the songs that will be put on the CD are relatively the same and you have to be careful that you don't overdrive the recorder because there is no compression or volume limiter in the loop.
