Thank you for that surprising info, SoundProgramer! I would have never considered trying CZlib due to its age. And I'm really shocked more CZ users in this group don't transfer sysex patches and banks to and from their PCs (or maybe they just don't care to share how they do it), as there are so many wonderful patches available for the CZs!!!
There's even a whole world of new sounds available by modifying the CZ sysex info to access parameters beyond the front panel limitations, like new wave combos, etc.. But there's little point if you don't have a solid means of transferring that data from a modern PC to your CZ!?
