Expression/crescendo
The 538/i548 has one pedal that can be used to control
the volume or the crescendo function.
When the
[CRESCENDO]
tab is off, the expression
shoe affects the volume (“expression” function). As
long as you do not change the “Expression” setting
(page 36), volume changes only affect manual II
(upper manual).
When you press the
[CRESCENDO]
tab (so that it
lights), the pedal acts as Crescendo pedal.
The Crescendo function adds more stops as you press
the pedal further down, adding richness and depth to
the sound. It does not affect the stops already in use
on the organ, but merely adds to them. There are
eight Crescendo steps, which are indicated by means
of a bargraph:
The stops added with each Crescendo step are preset.
To check your Crescendo step assignments:
• Move the pedal all the way up.
• Press
[0] (all tabs go dark).
• Press
[CRESCENDO]
(so that it lights).
• Press the pedal down and note how the tab indica-
tors (and the sound) change.
Tremulants
Tremulants create a change in amplitude (volume). They
add warmth and expressiveness to solo or small
ensemble combinations. It is not common to use
tremulants in larger classical ensembles. In some
romantic ensembles, tremulants are used judiciously. In
some gospel and evangelical musical traditions,
tremulants with a wider and deeper excursion are
frequently used.
The 538/i548 provides two
[TREMULANT]
tabs, which
affect only the stops in their respective division: MAN I
(lower manual) and MAN II (upper manual).
A tremulant is activated by pressing its tab (it will
light). The tremulants can be stored with registrations
in both general and corresponding divisional
memories.
Note: Each tremulant can be modified to suit your taste and
needs. See page 33.
