A digital synthesizer which utilizes special processing chips designed to support Casio's phase distortion synthesis architecture. Two CZ-1000's essentially in architecture and a sequencer.
Normally pretty reliable machines. Key contacts problems eventually. See the general repair tips for help with this problem if it arises.
I have replacement slider caps that fit the commonly missing CZ series sliders. They have a dished front so they grip better but stick up on the ends more than stock. Here is a photo of CZ5000 with them installed.
Let me know if there are common failing parts in these.
