What Is It?

The Rollerboard (German Wellenbrett) is essentially a mechanical switchboard whose job is to route mechanical signals from the keys to the valves (also called pallets/ventile). It is an essential component of any large Baroque-inspired pipe organ.

Designing a rollerboard is a bit like solving a Sudoku puzzle or laying out an array of transistors on a computer chip.
