Added new buttons and monitor support. Buttons would be without backlight, for loading oragans and temperaments, I guess. They are assignable anyways.
Here is what’s it looks like with the monitor. The buttons lit are “000”, STEP0 and General 0, sinse they have the same combination. The Organ loaded is Rotterdam Laurenskerk Demo – my favorite. The lowest piston board have yellowish color, thanks to the new pack of tact buttons, which I don’t like and gotta buy new ones to resolder.
