TRANSPOSER
Vast computer capability makes it possible to perform the sometimes difficult task of
transposing, while allowing the organist to play in the notated key. Operation of the
Transposer is controlled by the Transposer knob, found inside the Console Controller™
drawer underneath the left side of the console. Neutral (no transposition) position for the
knob is marked “
!
.” To shift the music to a higher key, move the knob counter-clockwise.
The key can be raised a maximum of five half-steps. To shift to a lower key, move the
Transposer knob clockwise from “
!
.” The key can be lowered a total of seven half-steps. A
RED INDICATOR LIGHT COMES ON WHEN THE TRANSPOSER KNOB IS MOVED FROM THE
“
!
” POSITION.
WHY TRANSPOSE?
1. Because the written range of a song will not always suit the vocal range of a particular
singer. By adjusting the transposer, the piece can be sung more comfortably and
effectively.
2. Because music for some instruments is not written in the same key as organ music. A
trumpet or clarinet in B
!
, for example, can read the same music as the organist, if the
Transposer knob is set two half-steps lower.
3. Because hymn singing can sometimes be improved by a more favorable key selection.
Hymn singing can also be enhanced by playing all but the final verse of a hymn in its
original key, followed by a short modulation to the key one half-step higher. After
changing the Transposer, the organist will then play the final verse in the original key,
but it will sound one half-step higher. If a hymn is already in a fairly high key, it may be
preferable to play the first few stanzas in the written key with the Transposer set
down
one half- or one whole-step; then modulate up to the original key and return the
Transposer to neutral for the final stanza (again played in the written key).
VIRTUAL ACOUSTICS™ SETTINGS
Virtual Acoustics™ provides the spatial ambiance of reverberant rooms of various sizes.
Although most effective in poor (non-reverberant) acoustic environments, it enhances the
sound even in excellent acoustic settings.
There are 21 selectable Virtual Acoustics™ pallets. One of these, the DEFAULT setting, is not
adjustable. The other 20 pallets are adjustable. They allow an organist to modify the sound
of the organ to accommodate a room’s changing acoustical properties. For example, a room’s
reverberation characteristics change as the number of people present changes. Differences
in reverberation time also occur when a room’s windows are opened or closed.
