Thank you for your INS File for the MZ-X500. This is very helpful for convering all my midi files in Casio Bank (Sound playback). I use the PSRUTI for change GM, Yamaha Midi Songs in special Casio Midi songs for Playback with the MZ-X500. I wished this service officially from Casio, as with Roland or others.
Thank you so much for your time and work!
