Thank you for this surprising info, SoundProgramer! I'm really shocked more people here aren't transferring sysex files (or using a modern Win OS), as there are so many impressive patches available for the CZs!
There's even a whole world of new sounds to be explored by modifying the CZ sysex data with a hex editor to achieve parameters beyond the front panel limitations, including new wave mix combos, etc.! But all that is pointless if there is no means to transferring that new data from a modern PC to your CZ!?!?
At least we have CZlib, I guess...! Thanks again SP!
