I've written up a summary of a conversation I've been having with someone trying to map out the keyboard matrix for a Casiotone CT-101.
I thought it might be useful to see the thought processes and theory as I've tried to suggest, remotely, things for them to try to get to the answer.
It's been surprisingly difficult to find information the CT-101 itself, but I've found details from several similar keyboards which has helped.

Maybe I'll try to incorporate this little guy from 1981 in one of my #jamuary songs. It is still with the notes taped to the keys as when I bought it. Didn't have the guts of removing them and ending with dual colored keys (i'm assuming the yellowing is not uniform and was caused by UV) #Casio #casiotone #m10 #music #synth #synthesizer #studio #boss #Japan #1980s
Pop quiz time, can you name a song by a famous band that used the Casio M10?. There is more than one...
I finally gave up finding a bag made specially for the #Casio #cz101. The cz101 is not very long and not very wide or thick. It is even smaller than the #cz230s. I had bought this Akozlin keyboard bag for a 49 keys, at 31"x10"x4" it fit reasonably well the cz230s, although a little long and wide. I bought another one to store the cz101. I just added a piece of black foam on one side. It's ok, not perfect, but serves its purpose.
I replaced the 2xAAA batteries in my EZCZ memory card but too late. The patches are garbled, but no big deal the CZ101 is easy to program. The ezcz has 4 banks selected by dip switches, each with 16 patches for 64 sounds. I don't even bother with the internal memory (held by 6 D batteries,, not convenient).
I now surprise own a Casiotone MT-100. Electronic Musical Instrument.
Ten US dollars today at the sale. A fraction of what it's worth.
Functions work well, it is gunked up tho, the volume pot is nasty dirty and the speaker sucks. Should be a great cleanup job!
And within 10 minutes it's already a blast to play with.
Dug out my old Casiotone VL-1 (VL-TONE) this morning. I bought this new, so it's.. quite old - must be well over 40 years old?
Amazingly it still works. I had forgotten it actually has an ADSR mode where you can "design*" the sound!!
*For a certain definition of "design"
