3D printed B system chromatic overlay for keyboards

[Jaoe]

Hi guys,
I play CBA and also have small Korg MIDI controller that would be great to play vertically with CBA layout. Did someone here every tried to 3D print some kind of overlay for piano keys? If do does it work ok and do you have CAD files with the project?

You can build your own CBA controller - have a look here for an example.

Thanks, I'll look into this. It's a shame that there are not much options where it comes to this. I saw some midi controllers from Musictech but the cost of those would justify buying used Roland. It would be great to be able to buy something small, like this but with real accordion buttons:

or sth like this:

Anyways probably will have to do some DIY project there

These things are easy enough to build yourself unless you're going for bellows, air sensors and remotely realistic response curves.
