Here again, not all models have this capability. MIDI and Style Player Download 3.3 on 56 votes MIDI and Style Player is a software program for playing and audition of MIDI and Yamaha keyboard Style files. The other option is to play the rhythm and save it to an internal Casio 'song' file, then use the keyboard's file control commands to export it as a MIDI file on an SD Card, and port that to a computer. Download 3.8 on 22 votes StyleMagicYAdemo lets you edit STY, PRS, and SST style files of Yamaha in SFF1, SFF GE (SFF2) formats and midi files in SMF0, SMF1 formats. This requires the keyboard to have the capability of outputing rhythm MIDI data to a MIDI port. Play the source Casio rhythm file (CKF, Z00, AC7) on a Casio keyboard and output its MIDI data to sequencer or DAW software on a computer, and record it as a MIDI file. There are two possible work-arounds you can try. The new MZ-X300 and MZ-X500 models can import rhythm files from competative models, but here again, that is going in the opposite direction from what you are looking for.

This was an adjunct module to their IDES Data Management Software, but it converted MIDI files to CKF rhythms (after a fashion), but not vice versa, as you are looking for. Casio did publish a converter program for the older WK-3XXX units, and their contemporary CTK counterparts. There is no converter software to do the 'direct' conversion that you are looking for.
