Yep, there was a guy posting here about it some months back. I think he had emigrated to Santiago de Chile.
Yep,... he still didn't die and still lives there; enjoying an ice-cream in hot Chilean summer.
I'm still at it... at desperately trying to convert my Tyros 3 zebra piano Kbd into Janko Kbd layout. Musical creativity is part of my inherited burden and so, whether I like or not ...have to put up with it. - My Tyros Kbd conversion will take a while, I stick to my whistling to musical creativity of whistling to music, which sadly was not welcome by some forum members.
To progress my Tyros 3 Kbd conversion, I tried to get plastic printers to fabricate the Kbd keys, but their quotes were about $500 for 61 keys.
So, I had to dream up another solution ...and found one:
I just use 0.3mm thin tin covers, which clip onto the keys to protect them. That offers me a firm surface onto which I then epoxy glue the square Janko keys and is easily reversible, in case I need to sell the Tyros later on.
The advantage of this Janko musical Kbd is that it offers hobby musicians (like me!) to play the Kbd 10x faster and easier; i.e. 1 year of Janko practice equals 10 years of zebra piano Kbd practice!! This advantage is too good to be missed.
Most accomplished zebra piano Kbd players hate the Janko Kbd idea, because to them it's "just unfair" for Janko players to enjoy all these benefits! Zebra piano players had to struggle the hard way to get there so, why should Janko players have it any easier?! "Why have it easier ...when it can be made more complicated!"
The same with traditional notation. That's why I invented my own WYSIWYG Janko notation, which allows to visually transfer the notes from the sheet music to the keys
and to forget about irregular scales practice and music theory. That makes sense, doesn't it? Here are some more details about it:
I also converted an old 120-button Farfisa accordion bass (bass section only) to MIDI. It was a hell of work combining, wiring/ soldering up all basses and chords via some 200+ signal diodes. This will enable me to enjoy musical creativity just like a singer or whistler, without bothering about irregular scales and chords with #+b and other Garbo irregularities.
Now all I would need is to find a PC programmer, who could accelerate the music conversion from traditional notation to my Janko notation.
Besides, I converted an old 120-button accordion bass (bass section only) to MIDI, fabricated a special cover for it, decorated it with cloth of my old shirt and sold it in two day for almost $400 on eBay. It was easy to do: I just added 24 switches onto it air flaps, but I didn't like it, for its 120 buttons had to operate the mechanics and that made the buttons hard to press, whereas my Farfisa accordion bass only activates one soft contact per button!!
Here's a great Janko piano Demo:
