Most of the electronics had to be custom developed as there was nothing available to cover all of the functionality of a classic Hammond B3 with the full drawbars set, preset keys and all switches. The Arduino platform was of great help for doing all the prototyping.

Based on the working prototype the final version of the electronics was developed. Everything was put onto one relatively small circuit board. This made space for the future integration of a computer into the controller.

The electronics for the white keys section of the two manuals as well as the actual manuals were bought from Doepfer. The manuals are similar to the ones used in the Nord C1 and Nord C2 combo organs and are manufactured by Fatar.
