I'd love to hear what you're doing with the CZ-101. CZ-5000 owner here.

Right now I'm just having fun poking around the code, investigating if there's much room for firmware modification. The CZ101 uses the NEC uPD7811 CPU, which has a really interesting architecture: It doesn't have any conditional branching, only conditional 'skipping' of instructions. I'll probably write something about the CPU at very least!

Something you have to consider if you want short fixed length opcodes. I guess you could call it "Macro Op Fission."

Casio's CZ/phase distortion synths are underrated, terrific sounding instruments (perhaps because of their 12-bit DAC?)

All synths should have (at least) 8-step envelopes like the CZ series.

Full multi-timbral hardware synths also seem rare these days.
