emulation accurate and open source casio synth emulation

[silent]

Greetings

I am looking for some accurate and open source emulation cores of casio synths, iPD and older.

If you can find them, please provide links to them in the replies to this post.

If you've made one and are willing to allow it to be used freely, please also share it here.

Thanks!

Some CZ-series synths are already emulated in MAME. The latency may be too high for live performance, but at least they do produce sound.
