Hi Joe,
I only just discovered your messages, since I hardly use this email address.
Any reason why you posted your messages as email rather than on the forum?
In answer to the content of your messages: the reason I try to get people interested in developing an affordable Janko keyboard is that at the moment nearly nothing is happening Janko-wise.
Also, there is no such thing as a Janko piano: the piggyback, the chromatone, the Lippens, the Daskin and my janko piano all have completely different dimensions. Any fingering suggestions would be for my specific keyboard, which is not very motivating for sharing ideas about playing technique.
In order to get people to play Janko and solve these problems, two elements are crucial: it has to be proven that Janko is a viable keyboard layout, by people actually playing it, and those interested will have to be able to get a keyboard somewhere. Of course the keyboard comes first.
At the moment I could not persuade any keyboard manufacturer that there is a market for a janko keyboard.
On the contrary, less and less people are active on the Facebook page, and Janko/chromatone players have a tendency to disappear off the radar. Those who actually own Janko pianos think it is a good idea to show you can move one interesting chord around, rather than play actual music, or show the advantages of the Janko layout in a convincing way.
I myself have not reached the point where I feel I could demonstrate these advantages as well as play convincingly on the janko.
The main reason I'd like to make a Janko keyboard a group project is that I don't have the technical knowledge to make one myself, and if I'd have a midi keyboard I could take the Janko outside the confinement of my living room. I reckon there are more people who would like to get their hands on a janko keyboard of some kind, other than the chromatone with its mini-keys.
A simple non-weigthed keyboard could be made very easily, especially using 3D printing technique. Even incorporating weights and levers doesn't seem too complicated. The crucial part is a simple midi interface with velocity-sensitive keys.
I can't believe that it would have to be so hard to get this stuff, looking at today's state of technology.
I've been emailing Evan Kale, who does a lot of tech stuff on youtube. Maybe he could design something. Also I'm mailing with midi-boutique, a supplier of midi goodies.
Who knows if this will lead to something.
cheers, Willem
