They have a CKF file extension on them which isn't mentioned anywhere in the documentation on the CTK-5000 for allowable file-types. None of the tone and other files there work (except for the few SMF MIDI files), but ALL the rhythm files work just fine. But I found no files for the CTK-5000 there. I went to the URL listed in the manual, where you can supposedly download extra tones, tunes, rhythms, etc. Just a heads-up for you CTK-5000 (& CTK-4000) owners. 428 Free Extra Rhythms (& Rhythm Editor) for Casio CTK-5000 & 4000
