Re: About me. (ROM dumps, make a Casio keyboard emulator?|CZ-230S firmware)

Hi Christian,

Thanks for the introduction. I have been on your website many times before, and have the table hooters section bookmarked. I am also interested in some of the old home keyboards, but perhaps not so devoted as you. I go on your website from time to time to read your opinion of some old keyboard.

I have also checked out the videos on your YouTube channel where you build up a track using looping and several different home keyboards. They are very entertaining, thanks for sharing.

As to the question, I am no expert on the subject, but I haven't heard of a serious attempt to get all the ROMs and then truly emulate the CZ sound engine. I believe I have seen attempts to mimic the synthesis style using some other software. But I can't even remember where I may have seen that.

I have heard people wish they had the ability to edit the firmware, to enable some killer feature, but I don't think that has happened yet.

Robin Whittle (firstpr.com) found out much about the Consonant-Vowel synthesis main voice sound ICs in early Casios, which would be useful to emulate them. Also the various Casio calculator emulators on the internet could be useful to understand what kinds of special CPUs Casio has
