Introduction
Congratulations on your purchase of a Kurzweil SPS4!
This manual will help you get acquainted with your new instrument. Be sure to keep the
manual on hand as you continue to familiarize yourself with the features and functions of
the SPS4.
Introduction
Main Features
Main Features
The SPS4 is a professional performance instrument. It boasts 128 excellent sounds
(including the famous Kurzweil Grand Piano) already on-board and ready to be played. It is
also a capable MIDI controller ideally suited for controlling additional sound modules and as
input to a sequencer.
Keyboard and Controllers
The SPS4 has an 88-key graded hammer-weighted keyboard action that provides you with
a piano-like feel without adding excessive weight to the instrument. The array of physical
controllers includes:
• a pitch touchpad
• a modulation slider
• an assignable control knob, which can control a parameter of your choosing
1-1
Introduction
Staying Current
Pedals (Optional)
As described above, the SPS4 has two jacks on the rear panel for optional pedal controllers.
One of these jacks is for one or two switch pedals, which are typically used to control
two-state (i.e., on / off) parameters such as sustain and mute zone. The other jack is for a
continuous control (or CC) pedal typically used to control a multi-state (i.e., “continuous”)
parameter such as filter frequency or LFO amount.
Note that switch pedals can be used to control continuous parameters just as continuous
control pedals can be used to control two-state parameters.
Your Kurzweil dealer stocks the following pedals:
• on the rear panel, two jacks for optional pedal controllers: one for a switch pedal and
the other for a continuous controller pedal.
• FS-1 Standard box-shaped switch pedal
• KFP-1 Single piano-style switch pedal
• KFP-2S Double piano-style switch pedal unit (one stereo plug)
• CC-1 Continuous pedal
Staying Current
Be sure to check the Kurzweil Music Systems website at www.Kurzweil.com for new
documentation and software updates before using your new instrument.
Do You Have Everything?
Your SPS4 package should contain the following in addition to your instrument:
• Power cable and 19V 3.42A power adapter
• Sustain pedal
• USB cable (Type-A-to-Type-B)
• Musician’s Guide (this book)
• Warranty card
If you don’t have all of these components, please contact your Kurzweil / Young Chang

Chapter 2
Getting Started
This chapter will help you hook up your SPS4 to your external sound system (if desired) and
MIDI system. If hooking up new gear is familiar to you, then simply read the following two
sections in this chapter. If you need more information, then be sure to read this chapter in
its entirety.
Getting Started
Before You Start…
Before You Start…
Don’t connect anything until you make sure your SPS4 is properly and safely situated. If
your SPS4 has been out in the cold, give it time to warm up to room temperature before
starting it, since condensation may have formed inside.
Quick Start
Make Connections
1. Set the keyboard on a hard, at, level surface.
2. Connect the power cable to the adapter then plug the adapter’s DC power cord into your
SPS4. Finally, plug the power cable into the wall.
3. Make sure your it is at a safe volume level. Also make sure that the SPS4’s MASTER
VOLUME slider (on the left side of the front panel) is all the way down.
4. If using an external sound system, run standard (1/4-inch) audio cables from your
amplifier or mixer to the Audio Outputs on the SPS4 (use the Left out for mono).
Balanced (“TRS” or “Stereo”) cables are recommended.
5. If you wish to use a CD or MP3 player or connect a second keyboard to the amplifier/
speaker of your SPS4, use a pair of standard 1/4” cables from your player or keyboard
to the SPS4’s Audio Inputs.

DC Power Jack
Start Up Details: The Rear Panel
Use Your SPS4
1. Power up your SPS4 first, and then raise the MASTER VOLUME slider. The SPS4 starts
up in Program mode by default. Press one of the Function buttons to the left of the
display to switch Modes.
2. If you hear distortion, in your external sound system, reduce the gain on your mixing
board, or use the pad (a switch that decreases the input audio signal level, typically by
20dB) if it has one.
3. Scroll through the program list with the Previous and Next buttons under the display,
or with the dedicated Bank, Group Select, and Sound Select buttons, and try the SPS4’s
many sounds. Take note that the User Bank is initially empty.
Start Up Details:
The Rear Panel
All of the connections take place on the rear panel of the SPS4, pictured below:
2-2
The MIDI (IN and OUT) Ports
Use the MIDI ports to communicate with other MIDI modules and controllers. The OUT
port is the MIDI transmitting port, and the IN port is the MIDI receiving port.
The Pedal Jacks
Use the two pedal jacks to connect controller pedals to the SPS4.
The Sustain (FOOT SW) Jack
Use the FOOT SW jack to connect a switch pedal. A switch pedal is a physical controller
typically used to control two-state (i.e., “on / off”) parameters, such as sustain and mute
zone. Note that switch pedals can be used to control “continuous” parameters as well.
The jack will also accept a dual switch pedal having a single stereo plug that is available
separately (Kurzweil KFP-2S). For more information on connecting pedals, see Connecting
Pedals on page 2-6.
The CC PEDAL Jack
Use the CC PEDAL jack to connect a continuous control (or CC) pedal. A CC pedal is a
physical controller typically used to control multi-state (i.e., “continuous”) parameters such
as filter frequency or LFO amount. Note that CC pedals can be used to control “on / off ”
parameters as well.
For more information on connecting pedals, see Connecting Pedals on page 2-6 below.
The USB Port
Use the USB port to connect the SPS4 to a computer in order to do the following:
• Use the SPS4 as a MIDI controller with a sequencer computer program.
• Use the computer to manage the user data contents of the SPS4.
Getting Started
Start Up Details:The Rear Panel
• Update the software and sounds of the SPS4.
Be sure to check the Kurzweil Music Systems website at www.Kurzweil.com for new
documentation and software updates before using your new instrument.
The Audio Out (LEFT/MONO and RIGHT) Jacks
Use the LEFT/MONO and RIGHT audio jacks to connect the SPS4 to an external
amplifier or mixer.
The Audio In Jacks
Use the LEFT and RIGHT Audio Input jacks to connect a CD or MP3 player or the audio
from a second keyboard to the sound system of your SPS4. These are “TRS” balanced
inputs. Using 1/4” balanced (stereo) cables will usually lessen extraneous noises such as
power line hum.
The DC Power Jack
Use the DC power jack to connect the DC power supply.
The HEADPHONES Jack (left cheekblock)
Use the HEADPHONES jack to listen to the SPS4 on stereo headphones. You will need a
1/4-inch-to-1/8-inch adapter in order to use headphones with a mini plug.
2-3
Getting Started
Connecting the Power Cable (Line Cord)
Connecting the Power Cable (Line Cord)
The SPS4 runs on 19 volts DC power and requires 3.4 amps to power the built-in amplifier.
Your dealer will provide the voltage adapter and power cord to match the AC power in your
area: 100, 120, 230, or 240 volts at 50–60 Hz. Plug the adapter into a wall outlet, and then
connect the adapter to the DC power jack.
Connecting to an External Audio System
Although your SPS4 contains a built-in high quality amplifier and speakers suitable for solo
playing in a small room, you may wish to use a more powerful external sound system for
large rooms and group playing. Needed are a pair of audio cables with 1/4” plugs on one
end and plugs compatible with your sound system on the other. If connecting to a mixer,
“balanced” (stereo) cables may transfer a stronger signal and lessen noise.
After you’ve turned down the level on your sound system, connect the SPS4’s analog audio
outputs to your sound system using a pair of stereo or mono audio cables. Mono cables will
always work, but if you’re going into balanced inputs, use stereo cables for a better signal-tonoise ratio and a bit more volume: the SPS4’s analog outputs are balanced.
You’ll find two 1/4-inch balanced audio output jacks on the rear panel. For now, connect
one end of each audio cable to your mixing board or PA system inputs, and connect the
other end to the jacks marked LEFT and RIGHT on the rear panel of the SPS4. If you have
only one input available, use the SPS4’s Left output to get the full signal in mono. Use the
front-mounted jack marked HEADPHONES to listen to the SPS4 on headphones. Note
that when headphones are plugged in, the built-in speakers are muted but sound still comes
through the LEFT and RIGHT audio jacks.

Connecting to an External Audio System
Your SPS4 features Left and Right audio input jacks for connecting to external signal sources
such as CD or MP3 players or a second keyboard. The audio input signal is mixed with
the SPS4’s own signal then the mixture is sent to the speakers, headphone jacks, and audio
output jacks. Note that the VOLUME slider only affects the volume of the SPS4 signal.
The Audio Input jacks are balanced so if your signal source has a balanced output and
balanced cables are used to connect, extraneous noises such as power line hum, are greatly
reduced.

Connecting Pedals
Connecting Pedals
Plug your switch or continuous pedals into the corresponding jacks on the SPS4’s rear panel.
We recommend using the Kurzweil pedals described in Pedals (Optional) on page 1-2, but you
can use almost any switch or continuous pedal that adheres to the following specifications
The pedals are independently assignable within each zone of every setup. Here are the
default settings for the three pedals you can use with the SPS4:
Switch Pedal 1Controller 64 (Sustain)
Switch Pedal 2Controller 66 (Sostenuto)
ring-sleeve (stereo) plug with the wiper connected to
the tip
CC PedalController 11 (Expression / Volume)
NOTE: Be sure not to step on the switch pedals when powering up your Stage Piano!
Connecting a Switch Pedal
When plugged into the SW PEDAL jack on the rear-panel, a single switch pedal will, by
default, act like a sustain pedal. Of course this can be changed by programming, as described
in Setup Mode on page 7-1.
If you use a third-party (non-Kurzweil) switch pedal, make sure it’s connected before you
turn on your SPS4. This ensures that the pedal will work properly (it might function in
reverse—off when it’s down and on when it’s up—if you turn on your SPS4 before plugging
in the pedal). Similarly, don’t press any of your switch pedals while powering up, as the SPS4
verifies each pedal’s orientation during power up—if you’re pressing a pedal, you might
cause it to work in reverse.
See Switch Pedal Problems on page 12-5if you are having trouble with your switch pedal.
Connecting Dual Switch Pedals
The jack will also accept a dual switch pedal having a single stereo plug. The plug should be
wired so that the left pedal connects to the ring contact and the right pedal to the tip contact.
It’s also possible to use two single pedals with this jack: first buy a 1/4-inch stereo-to-dualmono Y adapter (this will have two mono 1/4-inch phone jacks and a stereo 1/4-inch plug);
then, plug the pedal you wish to use for sustain into the left jack and your sostenuto pedal
into the right jack. Note that the “left” pedal goes into the right jack and vice-versa.
2-6
By default, the right pedal will control sustain as before and the left pedal will control the
sostenuto function. If you’re not familiar with traditional piano technique, the sostenuto
(center) pedal on a grand piano allows one to hold chords in the bass while continuing
to play the melody without the latter notes sustaining. Any keys that are down when you
depress the pedal will sustain when you let go of the keys, but new notes played afterward
will not be sustained. Releasing the pedal puts things back to normal. Of course it can be
programmed to do other functions as well.
Connecting a Control Pedal
A control pedal can be very useful for controlling volume, vibrato, or other effect by foot.
The Kurzweil CC-1 control pedal will work best with the SPS4, but it is also possible to use
third-party control pedals designed for synthesizers. Note that a volume pedal may or may
not be satisfactory depending on how it is constructed.
See Control Pedal Problems on page 12-6 if you are having trouble with your control pedal.

Connecting MIDI
Connecting MIDI
In addition to being a performance-suited musical instrument, the SPS4 is a powerful, but
intuitive and easy-to-use MIDI controller. For descriptions of how to customize your SPS4
as MIDI controller, and how to use its MIDI controller capabilities to their fullest potential,
see Setup Mode on page 7-1.
Basic MIDI Hookup
To use the SPS4 as a MIDI controller for another sound module, use a MIDI cable to
connect the MIDI port marked “OUT” to the MIDI input port of the module that you
want to control.
You may also connect the audio output of the module to the SPS4’s sound system with two
audio cables, see “Connecting to an External Audio System” on page 2-4. Even if you are not
using the SPS4’s speakers, it will mix the module’s sounds with your SPS4’s own sounds and
present the mix on the Audio Output jacks.
SP4Module
OutIn
To control the SPS4 using another MIDI controller, use a MIDI cable to connect the MIDI
port marked “IN” to the MIDI output port of the controller that you will be using.
ModuleSP4
Connecting More Sound Modules
In order to connect multiple sound modules to be controlled by a single MIDI controller,
your SPS4 must either be (1) used as the controller or (2) be the last module in the MIDI
daisy chain. This is because the SPS4 does not include a THRU MIDI port; however, this
simply means that the SPS4 must be at the start or at the end of the MIDI daisy chain.
Using the SPS4 as the controller, connect the MIDI OUT port to the MIDI IN port of the
first module, and then connect that module’s MIDI THRU port to the input of the next
module, and so on, until the last module is connected. The MIDI chain should end in the
MIDI IN port of the last module.

Connecting to a Computer Sequencer
To connect your SPS4 to a computer as a MIDI controller, simply connect the SPS4 to your
computer using the provided cable. If you wish to use your own cable, make sure that it is
a Type-A-to-Type-B USB cable (the USB port of the SPS4 being Type B). By default, the
SPS4 will act as a MIDI controller (rather than a hard drive) when connected to a computer.
If you are using a software synthesizer (“Plug-in”) or MP3 playback application on your
computer, you may connect the computer’s Line Out audio output to the Audio In jacks
of your SPS4 to use it’s sound system. This is especially useful if using your SPS4 as a high
quality native sound source and as a controller for a soft synth because both sounds will
come from the same speakers.

Pitch and Mod Controllers
Pitch Touchpad
The pitch touchpad is located on the left cheekblock. It works much like a traditional pitch
wheel or pitch bender lever but is more compact and less prone to wear out.
Like a bend lever or wheel, when not touched it is virtually centered and true pitch is heard.
Touching above the horizontal embossing will bend pitch upward, up to a whole tone sharp.
Touching below the embossing will bend pitch downward, up to a whole tone at. Smooth
bends are achieved by placing your finger where the horizontal and vertical embossings
cross and then sliding your finger along the vertical embossing while maintaining contact. To
restore normal pitch smoothly, slide back toward center. Or, simply release and the bend will
spring back to center (none).
Mod Slider
The mod slider is the leftmost slider control on the front panel. The mod slider is not spring
loaded so its handle remains where last released. Typically, the mod slider is assigned to a
parameter that alters some aspect of the sound (e.g., vibrato, filter depth) when changed.
Function Buttons
The Function buttons are located beneath the “Function” label on the left side of the front
panel. In addition to changing operating Modes, these buttons serve Mode-specific
secondary functions.

When in Setup Mode, holding down the Shift button while pressing the Split button will
mute or unmute (depending on the state of the zone) Zone 1 of the current setup.
Layer (Zone 2) Button
Pressing the Layer button will perform the Layer Function. With the Layer Function, you
can layer up to four different programs and setups – each layer is a new Zone, of which you
can have a maximum of four. The Layer Function is described further in The Layer Function
on page 5-4.
When in Setup Mode, holding down the Shift button while pressing the Layer button will
mute or unmute (depending on the state of the zone) Zone 2 of the current setup.
Transpose (Zone 3 and Zone 4) Buttons
Pressing the Transpose + button will transpose the current program or setup up by one
semitone; pressing the Transpose – button will transpose the current program or setup
down by one semitone. Pressing both Transpose + and Transpose – simultaneously will
restore the current program or setup to having no transposition; if these two buttons are
simultaneously pressed when there is already no transposition, then the current program or
setup will be transposed down by one octave (12 semitones).
When in Setup Mode, holding down the Shift button while pressing the Transpose –
button will mute or unmute (depending on the state of the zone) Zone 3 of the current
setup. Holding down the Shift button while pressing the Transpose + button will mute or
unmute (depending on the state of the zone) Zone 4 of the current setup.
Shift Button
When in Setup Mode, holding down the Shift button activates the secondary functions (i.e.,
Zone mute) of the Split, Layer, Transpose –, and Transpose + buttons. When holding
down the Shift button, the button of each active zone will be illuminated and the button of
each muted zone will be blinking.

The Control Knob
The assignable control knob is a powerful and exible—yet intuitive—feature of the SPS4.
It provides you with real-time control of five parameters. In Program Mode and Setup
Mode, these parameters are preset. In Edit Setup Mode, you can change what these
parameters are.
The control knob gives you real-time control of five different parameters—the currently
selected parameter is indicated by the column of LEDs. By default these five parameters are:
Features of the SPS4
The Control Knob
• 1 Timbre
• 2 Mod
• 3 Envelope
• 4 Effect
• 5 Reverb
You can change what these five parameters are in Edit Setup Mode (see Edit Setup Mode on
page 8-1).
Pressing the Control Select button (located beneath the column of LEDs) changes the
currently selected parameter that is affected by the control knob.

Display and Value Buttons
The alphanumeric display and Value buttons below it are located close to the center of the
front panel.
Previous (–) and Next (+) Value Buttons
Use the Next and Previous buttons to scroll through the list of items on the display.
Pressing both the Next and Previous buttons simultaneously will jump to the first entry of
the next category of items in the list. For example, when in Program Mode with program 1
Studio Grand currently selected, pressing Next and Previous simultaneously will jump up
the list of program to program 8 Stevie’s Rhds, the first of the Electric Piano programs.
Pressing the two buttons again will jump up to program 16 Supasticious, the first of the
Clavinet programs.
Chan / Param Buttons
In Program Mode, pressing the Chan / Param Up () button will change the MIDI
transmit channel from the current channel to the next one; pressing the Chan / Param Down () button will change the MIDI transmit channel from the current channel to the
previous one.
In the all of the Modes other than Program Mode and Setup Mode—i.e., Edit Setup, Global,
and System—pressing the Chan / Param buttons will scroll through the parameter list of
the current Mode.

Object Select Buttons
The Object Select Buttons are located on the right side of the front panel. Note that there
are three types of Object Select Buttons: Bank Select, Group Select, and Sound Select. The
Programs and Setups of the SPS4 are organized in three levels of organization: eight Sounds
make up a Group, eight Groups make up a Bank. The following figure illustrates this
organization using the Program 42 Jump! 0bx as an example:

Features of the SPS4
Object Select Buttons
Bank Select Button
Pressing the Bank Select button will cycle through the three object banks: Bank 1, Bank 2,
and User. The column of LEDs indicates the currently selected bank. In Program Mode,
Bank 1 contains programs 0-63, Bank 2 contains programs 64-127, and User Bank contains
user-created programs numbered 128-191. In Setup Mode, Bank 1 contains setups 0-63 and
User Bank contains user-created setups numbered 64-127.
NOTE: A “Bank” is a SPS4-specific term not to be confused with the general “MIDI
Bank”, which contains 128 Objects. When transmitting bank change and program change
MIDI messages, always think in terms of “MIDI Banks” rather than “Banks”.
Group Select Buttons
As pictured below, there are eight Group Select buttons. Note that each button corresponds
to a different Group depending on the currently selected bank.
Each bank is divided into eight Groups. Pressing the Group Select button immediately
beneath each Group label will select that Group within the current bank. The LED of the
currently selected Group’s button will be lit.
Sound Select Buttons
3-8
Each of the Sound Select buttons corresponds to one Sound in the currently selected
Group; pressing one of these buttons will select that Sound. The LED of the currently
selected Sound’s button will be lit.
