If you followed the instructions shown on pages 3 and 4, you should see the FOOT SWITCH 1
FUNCTION Mode Page. The box to the right of “DEVICE” should be highlighted.
tFOOT SW 1
DEVICE
The Foot Switch (FOOT SW) jack on the Sk-series instruments is set up to accept different types of
devices. The data chart below shows the options you may select.
FOOT SWITCH DEVICE SELECT Options
Description Function
Foot Switch A conventional foot switch such as the Hammond FS-9 or other conventional 3rd-party foot switches.
Leslie A “half-moon” style speed switch, available as an optional accessory, which allows you to select the
Leslie Speeds.
Turn the VALUE knob to make your selection.

Special Performance Features 9
From the screen shown on the previous page, press the DIRECTION “q” button once.
The box to the right of “TIP MODE”should be highlighted.
TIP MODE / RING MODE
What Is “TRS?”
A typical momentary Foot Switch will connect to an instrument such as the SK PRO by means of a plug
similar to the one shown below.
TRS is an acronym for Tip-Ring-Sleeve, and refers to the fact that a connecting plug can have more than
one connector. This means that more than one Foot Switch can be connected to the SK instrument,
thereby allowing you to control more than one function using the same Foot Switch jack. If you wish to
do this, you will need a Stereo Adapter which has a Stereo plug and two (2) Mono jacks.
NOTE: This type of adapter is also called a “splitter.”
Insert the Stereo plug into the FOOT SW jack on the SK instrument and connect a Foot Switch to each of
the Mono input jacks. In most cases, the Left (L) input jack will access the Tip function while the Right
(R) will access the Ring function.
NOTE: You can also use a TRS cable to connect a dual-momentary switch to one of the FOOT SW jacks. If
you do this, one of the switches will be assigned to Tip mode and the other to Ring mode. However, if you use
a dual-switch which allows you to select either Latching or Momentary operation, be sure to select Momentary
to use the switch with the SK PRO.
NOTE: The plug-in receptacles on some commercially available adaptors may be marked TIP and RING for
easier identification. Follow these markings when setting up your Foot Switches.
NOTE: If you connect a Foot Switch while the power to the instrument is “OFF,” the polarity of the connected
Foot Switch(es) is/are automatically detected when the power to the instrument is turned “ON.” However, if you
have connected Foot Switches or a Damper Pedal while the instrument is “ON” and it is not working correctly,
you can calibrate them by following the procedures described on pages 12 and 21.

Special Performance Features10
If you followed the instructions on pages 7 and 8, you should now see the FOOT SWITCH 1
FUNCTION MODE Page. The box to the right of “TIP MODE”should be highlighted.
There are 13 settings for the Foot Switch. The data chart below explains each one.
Foot Switch Settings
Parameter Description
Off Pressing the Foot Switch will have no effect.
Leslie S/F ALT Allows you to use the Foot Switch to switch back and forth between Leslie Slow and Fast Rotor
Speeds. Each time the Foot Switch is pressed and released, the Leslie Rotors will change speeds.
Leslie S/F MOM Allows you to use the Foot Switch to switch Leslie Rotor Speeds. When the Foot Switch is pressed
and held, the Leslie Rotors will go at Fast speed. When the Foot Switch is not engaged, the Leslie
Rotors go at Slow speed.
Leslie S/F TRI Allows you to use the Foot Switch to switch back and forth between Leslie Slow and Fast Rotor
Speeds similar to the ALT mode. Additionally, if the Foot Switch is pressed and held for longer than 1
second, the Leslie Rotors will go to the Off or Stop position.
Tone Wheel Brake Allows you to bend the pitch, with the amount being determined by a Parameter setting.
*Favorite Fwd Allows you to use the Foot Switch to move forward through the Favorites.
*Favorite Rev Allows you to use the Foot Switch to move backward through the Favorites.
+Spring Shock Allows you to use the Foot Switch to add the sound of a Spring Reverb unit being jostled.
Delay Allows you to adjust the Delay Time of the Effects, at the interval of pressing the Foot Switch. The
delay is heard while the Foot Switch is held down
Organ U&L Sustain Allows you to add Sustain to the UPPER/LOWER Part(s) of the ORGAN Section.
Pedal To Lower Allows you to use the Foot Switch to turn PEDAL TO LOWER “ON.”
++Bass 1C ~ Bass 3C Allows you to use the Foot Switch to play a specific Pedal note.
ProChord Allows you to add ProChord harmony.
* - By selecting “Favorite Fwd, Rev,”Favorites can be selected sequentially by using the Foot Switch to advance
either forward or backward. Also, if either “1" or “10" are selected, the sequence will “roll over” to the next
numbered Bank
+ - “Spring Shock” occurs when the springs in a spring reverb unit move around and strike the reverb tank,
resulting in a loud “bang” Some modern and progressive music uses this as a musical effect.
++ - Many jazz and blues organists provide a bass line with the left hand on the Lower Manual and strike one Pedal
note at the onset of each bass note to give the effect of a plucked string bass (called a “thump”).
NOTE: All of the above functions can be set for either Tip or Ring Mode. However, Ring Mode will have
no effect if only one Foot Switch is connected to the FOOT SW jack. You can then use Tip Mode to
select the function you want.
Use the DIRECTION “p” and “q” buttons to select either TIP MODE or RING MODE.
Turn the VALUE knob to make your selection.

Special Performance Features 11
From the screen shown on the previous page, press the PAGE “u” button once.
The box to the right of “TIP MODE” should be highlighted.
This FUNCTION Mode Page allows you to select the Function of devices connected to the FOOT SW 2
jack.
This Page is identical to the FOOT SWITCH 1 Page with one exception: The DEVICE Parameter is not
included in the FOOT SWITCH 2 Page because the FOOT SW 2 jack will not accept a Leslie Speed switch
(Leslie CU-1 - available as an optional accessory). If you wish to use a Leslie switch to control the speed of
the Leslie rotors, plug the Leslie switch into the FOOT SW 1 jack and select Leslie as the DEVICE as shown
on page 8.

Special Performance Features12

The box to the right of “LIMIT HF” should be highlighted.
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 flatter frequency response will be perceived by
the ear.
LIMIT HF
This FUNCTION Mode Page allows you to adjust the amount of High Frequencies (above 800Hz) that will
be heard when the Expression Pedal is set at minimum. You can select Off (no sound), or from 0db to -
40db (minus 40 decibels).
