Has any manufacturer tried having electro-mechanical actuators in place of the complex pure mechanical system?
Frankly I would rather to have to depend on electricity than accept the high costs of traditional design. An electric system would be so easy to implement! Yes you may not be able to slide a note in flight with utmost control but the mechanism would be greatly simplified. Much less stuff to regulate as well. Notionally 7 3-throw switches would do it and it paves the way for more than 7 and custom settings to “prepare” the instrument to do unusual stuff or strange combinations and even for computer control. If the neck is to be reshaped we can go way more than plus or minus 1 semitone. Still this is not influencing the acoustic part. The concept that all notes must change together can also be challenged because wiring/program control of electrical can be much more flexible than mechanical contraptions. Even upgrade kits for lever harps can be devised.
The technology existed for more than a century.
Why wouldn’t anyone sell this already?
