The CZ synths were really underrated, I think because the presets IMHO are a bit rubbish.
I still love them though. Phase distortion can make some really great noises with a bit of coaxing.
I have the bigger CZ-5000 with the built in sequencer I bought used in the 90s and still play. I think it was probably used most famously by Drexciya but the Kevin Saunderson "Reece Bass" sound was everywhere in early jungle.
I like this CZP-1 soft synth. It's pretty nice once you flip the flow from left to right to top to bottom.
I wonder what the modus operandi of preset makers is. Like, the "Boards of Casio" patch data here is amazing, usable, playable. But the official patch banks of many synths, VSTs etc. are quite unusable. Maybe they're aiming to show the breadth of what sounds you can get out of it, rather than provide good defaults?
Agreed. I was lucky and found both a CZ-1 and a VZ-10m at low cost in the late 90s/early 2000s. I'm happy to see people exploring their synthesis mechanism in a form with a better UI.
I you have CZ-5000 you’re probably aware of Satoshi & Makoto who are making music using only CZ-5000 with its 8-track sequencer.
