Bass Coupler - Rodgers Trillium T967 Owner's Manual

Melody couplers are intended to be used when the corresponding intermanual coupler is not
engaged. For example, when Melody from Swell is engaged, the Swell to Great couplers should
not be used to achieve the proper "Melody" affect. Likewise, when Melody from Choir is
engaged, the Choir to Great couplers should not be used.
In its default setting, the Melody Coupler operates when the top note (the melody note) is
between keys 25 and 61 on the Great manual. However, the lower end of its range is
programmable and may be extended down to key 13 or up to key 49. See page 28.

Melody Couplers can be set only in General combination pistons.

Bass Coupler

The Bass coupler is much like the Melody couplers 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 engaged, 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 is can extend up to key 32 (top of the pedalboard range). See page 28 for more details.
