The Polyphony Expansion Kit
Thanks for purchasing the PCX-1 Polyphony Expansion Kit! This kit (part number 140071)
doubles the polyphony of Kurzweil PC2s—from 64 voices to 128. This document contains
instructions for installing the PCX-1 in all PC2 models: the 76-key PC2, the 88-key PC2X, and
the rack-mount PC2R.
Please read the all of the introductory information (through Tools and Materials Required for
Installation) before proceeding with the installation. Then go to Installing in Keyboard Models on
page 6 if you’re installing the PCX-1 in a keyboard, or Installing in Rack-Mount Models on page 12
if you’re installing it in a rack unit.
Contents of the Kit
In addition to this document, your PCX-1 kit should contain the following items:
•
•
•
•
Polyphony Expansion board (PCX-1 board)
Two screws (not needed for keyboard models)
Floppy disk containing operating system and boot block software
Floppy disk containing soundware
Safety Precautions
To prevent risk of electrocution, make sure that the PC2 or PC2R is disconnected from its power
supply before you begin disassembling the instrument.
Static electricity, even in small amounts, can cause damage to electronic components (especially
memory). Before disassembling the instrument, touch a conductive metal surface to discharge
any static electricity that you may have built up.
System Requirements
All PC2 series instruments contain three main software components:
Operating system software
Soundware
Boot block software
Defines the performance and editing characteristics of the PC2.
Defines the characteristics of programs and setups.
Contains diagnostic software and other functions (like software
updates) not related to performance or editing.
Each of these components must be Version 2.0 or later for you to be able to use the PCX-1. If you
have a rack-mount PC2R, you don’t need to check your software versions, since all PC2Rs have
at least Version 2.0 of these software components. If you have any of the keyboard models, you’ll
need to check the versions of all three components, as described below.

The Polyphony Expansion Kit
System Requirements
Checking Software Versions
Remember, if you have a rack-mount PC2R, you already have Version 2.0 or later of all three
main software components, so you don’t need to check your software versions (you can proceed
to Installing in Rack-Mount Models on page 12).
If you have a keyboard model, you do need to check your software versions. As you check each
software component, make a note of whether you need to update it. If you don’t need to update
any components, proceed to Removing the Access Panel on page 9.
Checking the Boot Block Software Version
The boot block isn’t accessible during normal PC2 operations, since the only time you’ll need to
use it is when you want to run diagnostics, install a ROM sound option, or update software.
To activate the boot block, turn the instrument on, and watch the display (if it’s already on, turn
it off then on again). When you see Please|wait..., press and release the Panic button. This
starts the boot block. After a few seconds, you’ll see another message indicating that you’re
running the boot block. The bottom line of the display shows the version of the boot block
software. This message doesn’t remain visible for long, so check it quickly. If the version number
is lower than 2.0, you need to update your boot block (see page 6).
To return to normal operation, press the Right cursor button until you see Run|engine in the
bottom line of the display, then press Yes.
Checking the Operating System Software Version
There are two ways to check the version of the operating system software. The first is to watch
the display as the instrument powers up. During powerup, the display shows several messages.
One of these messages is Welcome|to|the|PC2; this message also indicates the version of the
operating system software on the bottom line of the display.
The second way to check the version of the operating system software is to check the value of
one of the parameters in the Global menu. Press the Global button, then press the Right cursor
button until you see a parameter called OS Version.
Whichever method you use, if the operating system version is lower than 2.0, you need to
update your operating system software. See Updating Operating System Software on page 7.
Checking the Soundware Version
To check the version of your soundware, select Program 127 in the User bank (Bank 1). This is a
sine wave that the PC2 uses in its internal diagnostics. The program name is Sine, followed by
the soundware version number. If this number is lower than v2.0, you need to update your
soundware (see page 7).

Tools and Materials Required for Installation
Tools and Materials Required for Installation
•
•
#1 (small) Phillips screwdriver
Two thick foam pads (keyboard models only)
You’ll need a flat work area large enough to accommodate the disassembled instrument. Most
tabletops will work for the PC2R, but keyboard models require more space—up to 60-by-30
inches, depending on the length of the keyboard. The foam pads listed in the required materials
will protect the Alpha Wheel and sliders on keyboard units.
Tools and Materials Required for Software Updates
If you own a keyboard model and you need to update your operating system software,
soundware, or boot block, you’ll also need the following:
•
•
Standalone sequencer or MIDI file player that has a floppy drive and can send System
Exclusive (SysEx) data—or a personal computer (either Windows-compatible or a
Macintosh or other computer capable of reading DOS disks and files) equipped with MIDI
interface, floppy disk drive, and sequencing software capable of sending SysEx data.
MIDI cable
Sequencer Software for Windows-Compatible Computers
For Windows-compatible computers, we recommend using Windows Media Player, which you
can download from the following site:
http://www.microsoft.com/windows/windowsmedia/en/Download/default.asp
We’ve also tested Cakewalk and Logic, although some versions of Cakewalk send the SysEx
data too quickly for the PC2 to process. If you use Cakewalk and you’re unable to update, please
see Cakewalk’s on-line help, which describes how to modify an INI file to reduce the SysEx
transmission speed.
Sequencer Software for Macintosh
We’ve tested MIDIGraphy 1.4.3, which you can download from the following site (note that
there’s no “www” in this URL):
http://member.nifty.ne.jp/mmaeda/e/works.html
Older versions of MIDIGraphy tend to crash with Mac OS 8 and 9. Additionally, Windows
Media Player for the Macintosh does not work at all.
We’ve also tested Performer 5.0.1 (at tempos up to 215 BPM), and Logic.

If you haven’t checked the versions of your boot block software, operating system software, and
soundware, do so before beginning installation. The PCX-1 requires Version 2.0 or later of all
three of these software components. See Checking Software Versions on page 4 to learn how to
check software versions. If you need to update one or more software components, see Updating
Software below. Otherwise, turn to Removing the Access Panel on page 9.
Updating Software
You’ll need to update any PC2 software components that aren’t Version 2.0 or later. Updating
the software is extremely convenient; all you have to do is load one or more MIDI files into the
PC2’s flash ROM using a sequencer application. Here’s how to set it up.
Saving Objects
Updating software components requires you to do a hard reset before resuming normal
operations. This deletes all information from the PC2’s memory. You should dump all userdefined programs, setups, and effects to an external memory source (like a computer sequencer)
before updating your software. Otherwise, they’ll be lost.
Preparing Your Computer
1. Connect a MIDI cable from the MIDI Out port on your personal computer or MIDI
interface to the PC2’s MIDI In port.
2. Launch the sequencer application on the personal computer.
Launching the PC2’s Boot Block
You’ll need to run the boot block for any software updates you make (including updating the
boot block itself).
1. If the PC2 is on, turn it off.
2. Turn the PC2 on, and watch the display.
3. When you see Please|wait..., press and release the Panic button. After a few seconds,
you’ll see Main|Menu in the top line of the display, and Install|engine in the bottom
line. This is the boot block.
4. Follow the instructions in one or more of the following subsections, depending on which
software components need updating.
Updating Boot Block Software
1. When the boot block has finished launching, press the Right cursor button until you see
Update|boot|block in the bottom line of the display.
2. Press Yes. The display changes to Update|boot|block|via|MIDI.
3. Press Yes. The display changes to Waiting|for|MIDI.
4. Insert the PC2 operating system/boot block disk into the floppy drive of your computer.
5. Using the sequencer application on your computer, open the MIDI file named
PC2BK200.MID.
6
The Polyphony Expansion Kit
Installing in Keyboard Models
6. Play the MIDI file. The top line of the display shows SYS3-0|file|1|of|1, and the
bottom line shows segment|1|of|1. This file takes just under a minute to load at 215
beats per minute. When the file finishes loading, the PC2 will restart and return to a
performance mode.
7. Turn off the PC2, then turn it back on and press Panic when you see Please|Wait... in
the display. This launches the new boot block. You should see the new version number as
the boot block launches.
8. Follow the instructions in one or both of the following subsections, depending on which
software components need updating. If you need to update the boot block software,
chances are that you’ll need to update both the operating system software and the
soundware as well. However, if you don’t need to update any more software components,
proceed to Doing a Hard Reset (page 8).
Updating Operating System Software
The operating system software, together with the soundware data, are part of the PC2 sound
engine. You’ll use the Install|engine (sound engine) option to install both the operating
system software and the soundware.
1. When the boot block has finished launching, press Yes (this selects the Install|engine
option, which is the first option in the boot block menu). The display changes to
Install|engine|via|MIDI.
2. Press Yes. The display changes to Waiting|for|MIDI.
3. If necessary, insert the PC2 operating system/boot block disk into the computer’s floppy
drive.
4. Using the sequencer application on your computer, open the MIDI file named
PC2K200.MID. Set the tempo to 215 beats per minute.
5. Play the MIDI file. The top line of the display shows SYS3-0|file|1|of|1, and the
bottom line shows segment|1|of|8. This file takes about four minutes to load at 215
beats per minute. When the display shows Done, stop the sequencer (some sequencers
will stop automatically at the end of the SysEx data).
6. Press Cancel. The display shows Install|engine|via|MIDI.
7. Follow the instructions in the next subsection if you need to update soundware data. If
you don’t need to update soundware, proceed to Doing a Hard Reset (page 8).
Updating Soundware
The soundware data, together with the operating system software, are part of the PC2 sound
engine. You’ll use the Install|engine (sound engine) option to install both the operating
system software and the soundware.
This procedure assumes that you’ve just finished launching the boot block, and the bottom line
of the display shows Install|engine. If instead you’ve just finished updating the operating
system software (and the display shows Install|engine|via|MIDI), go to Step 3.
1. Press the Left or Right cursor button until you see Install|engine in the bottom line
of the display.
2. Press Yes. The display changes to Install|engine|via|MIDI.
3. Press Yes. The display changes to Waiting|for|MIDI.

4. Insert the PC2 soundware disk into the floppy drive of your computer.
5. Using the sequencer application on your computer, open the MIDI file named
PC2S200.MID. Set the tempo to 215 beats per minute.
6. Play the MIDI file. The top line of the display shows SYS3-0|file|1|of|1, and the
bottom line shows segment|1|of|13. This file takes a little over six minutes to load at
215 beats per minute. When the display shows Done, stop the sequencer (some
sequencers will stop automatically at the end of the SysEx data).
7. Press Cancel twice to return to the boot block menu.
8. Do a hard reset, as described in the following subsection.
Doing a Hard Reset
Remember that a hard reset deletes all user-defined programs, setups, and effects. If you haven’t
saved these objects and you don’t want to lose them, follow the instructions in Returning to
Normal Operations, then dump the objects you want to save before doing the hard reset. Once
you’ve saved the objects, do the hard reset (in this case, the easiest way to do the hard reset is to
use the Reset PC2? option in the Global menu).
This procedure assumes that you’re in the boot block menu. If you aren’t, relaunch the boot
block (see page 6 if you need a reminder), then proceed.
1. Press the Left or Right cursor button until you see HARD|RESET in the bottom line of the
display.
2. Press Yes. The display prompts you with a question: Erase|RAM|objects?
3. Press Yes. This performs the hard reset and returns you to the boot block menu.
4. Follow the instructions in Returning to Normal Operations below.
Returning to Normal Operations
1. Press the Left or Right cursor button until you see Run|engine in the bottom line of the
display.
2. Press Yes. After a few seconds, you’ll be back in a performance mode. You’re now ready to
begin the installation of the PCX-1 board. Turn to page 9.
Troubleshooting for Software Updates
You’re not likely to have problems updating your software. In fact, there are very few things that
can go wrong:
Display is Stuck at “Waiting for MIDI”
The MIDI signal isn’t getting to the PC2. Make sure that the computer’s MIDI Out is connected
to the PC2’s MIDI In. Make sure the cable isn’t defective. Try another cable if necessary.
Display Never Shows “Done”
The PC2 isn’t receiving all of the MIDI file data. Try playing the MIDI file at a lower tempo.
If you’re still having problems, consult a Kurzweil dealer or service center.

Removing the Access Panel
The PCX-1 board fits into the access opening at the bottom of the keyboard, so the first step is to
remove the panel.
1. Make sure that the PC2 is disconnected from its power supply, and that you’ve discharged
any residual static electricity by touching a conductive object (like the metal casing of the
PC2 itself).
2. Position the foam pads on your work surface so that they’ll support the ends of the
keyboard.
3. Place the PC2 face-down on the foam pads, with the keyboard facing away from you.
Make sure that the PC2 is not resting on the Alpha Wheel or sliders.
4. Using a #1 Phillips screwdriver, remove the seven screws that secure the access panel, as
shown in Figure 1.

2. Identify the 24-pin female connector (J805) on the PCX-1 board. It’s on the bottom of the
board—all of the other components are on the top of the board. Also notice the four holes
that will align with the standoffs on the Engine board.
3. Grasp the board as shown in Figure 3 (page 11). The connector (J805) should be at the left
side of the board, and facing away from you. Holding the board vertically, insert it
through the access opening, then rotate it until it’s horizontal.
4. Align the holes in the PCX-1 board with the standoffs on the Engine board. This will align
the connectors. All four standoffs should protrude through the PCX-1 board.
5. Snap the PCX-1 board onto each of the four standoffs, one at a time, by pressing on the
board near the location where each standoff protrudes through the board. You should
both feel and hear the board snap into each standoff.
