If you are trying to load in sound data , you must make sure the CZ-101 has MIDI-SYSTEM EXCLUSIVE . If it does , make sure you have it activated and instruct it to receive patch data . If it does not have SYSTEM EXCLUSIVE than it will not receive patch data . Since that keyboard was made in 1984-85 it may not have it , very few did . The 101 was the entry level of the CZ series.
