Bass Coupler
The Bass coupler is much like the Melody coupler described above, except that it adds the Pedal
registration to the lowest note played on the Great manual. This allows you to easily add a Pedal
part to anything played on the Great manual.
The BASS coupler is located on a thumb piston beneath the Great manual. When activated, the
piston lights, and any selected registration in the Pedal division will sound from the lowest key
being played on the Great manual. This provides a pedal bass sound without actually playing the
pedalboard. In the default setting, the Bass Coupler affects keys 1 through 24 of the Great
manual, but its range can extend up to key 32 (top of the pedalboard range). See AG.

The Bass Coupler can be set only in General combination pistons.
