Editing Parameters
EXPRESSION PEDAL
Th is Page allows you to control how a connected Expression Pedal will function.
SOURCE
Th is allows you to select the source of expression control.
Exp. Pedal ..... Instrument Expression is controlled by a connected Expression Pedal.
MIDI .................. MIDI Expression Data (CC#11) will be received at the UPPER Keyboard Channel.
Both .................. Instrument Expression is controlled by both Expression Pedal and MIDI Expression
data.

REVERSE
Th is allows you to set the polarity type of a connected Expression Pedal.
Normal ............ Hammond EXP-50J pedal, etc.
Reverse ........... Expression Pedal with reverse polarity.
ORGAN MINIMUM LEVEL
Setting Range: Off , -40 ~ 0 [dB]
Th is allows you to set the amount of volume when the Expression Pedal is “closed” or
set at its minimum position. At “0” no sound will be heard.
LIMIT HF
Setting Range: Off , -40 ~ 0 [dB]
Th is allows you to adjust the amount of High Frequencies (above 2kHz) that will be
heard when the Expression Pedal is set at minimum.
LIMIT LF
Setting Range: Off , -40 ~ 0 [dB]
Th is allows you to adjust the amount of Low Frequencies (below 500Hz) that will be
heard when the Expression Pedal is set at minimum.
GAIN
Setting Range: 70 ~ 130 [%]
This allows you to adjust the range of a connected Expression Pedal. To set this
parameter, depress the connected Expression Pedal at maximum, and set this parameter
to the minimum value that the Expression Monitor
indicates “127”.
CURVE
Setting Range: 1 ~ 3
Th is allows you to set the “curve,” or change of expression value corresponding to the
angle of the Expression Pedal when depressed (see the illustration on the right).
MONITOR
Setting Range: 0 ~ 127
Th is allows you to display the current Expression Value, with “0” being minimum
Expression (no audible sound) and “127” being maximum Expression. Th e Expression
Monitor can be useful as a troubleshooting aid if you either don’t hear any sound or
can’t change the volume using a connected Expression Pedal.
EXPRESSION LIMIT
On many home audio components, there is a
control called “Loudness.” This is intended to
correct an anomaly of the human ear whereby
high and low frequencies appear to be lacking at
low volume levels.
The SK PRO incorporates a “Loudness” algorithm
similar to the one found on home audio. At lower
volume levels, both high and low frequencies are
boosted so that a fl atter frequency response will
be perceived by the ear.
