I double checked. The midi file I mentioned is in the CZ Sounds folder > Dr. Steve's Patch Test Files. If you want to use midi-ox to transfer data between the CZ and a PC, you might also want to look at the screen shots in the Using Midi-Ox with Your CZ folder. I believe there is a thread from around that time that addresses how to use midi-ox. I just have some screen shots, including two where some of the sysex bytes are labelled. You should also be able to use the same technique with songs.
