I've found my niche, which is asking someone else to rebuild these gadgets rather than trying to do it myself. I can just dream up a fingering chart and a few extra functions and send off an email. Bliss.
I've requested this as the default layout, chromatic over two octaves. I think that'll fall under the fingers OK.
(By the time the manual has been fed through Wayback and Google Translate, it's difficult to find out what the original settings were.)

It interests me to know how the microprocessor is being made to handle that number of inputs - I've never figured that part out!
Most digital systems that feature more than a moderate number of user switches would organise them as a scanned matrix with each switch connecting together a unique combination of row and column.
With this sort of arrangement one could accommodate, for example, 64 switches with an 8 row by 8 column matrix. An explanation of this with a music tech relevant example can be found here. The examples show the columns being driven by microprocessor outputs with the rows as inputs.
