This zipped archive includes the version 1.07b Operating System for the PC2. 

PLEASE NOTE THAT THIS IS A BETA VERSION. ALTHOUGH WE BELIEVE IT TO BE FREE OF ANY MAJOR PROBLEMS, WE RECOMMEND THAT YOU BACK UP YOUR USER PROGRAMS AND SETUPS BEFORE UPDATING. If you encounter any problems, please send email to support@kurzweilmusicsystems.com with details of the problem you encountered. We also encourage you to check back on our web site for newer releases:

We normally recommend doing a Hard Reset after installing a new file. Therefore, if you have any user created Programs or Setups, you should do a system exclusive dump of the memory before updating. Please read Resetting the PC2 on page A-5 of your manual for more info.

Details on how to update your PC2 can be found in your manual, starting on page A-3, however, for convenience sake, we have also detailed the upgrade procedure below.

These files are in Standard MIDI File  (.MID) format, therefore you will need a software program or hardware sequencer, such as one built into a keyboard, or a stand alone sequencer or MIDI file player. The files contain system exclusive data, and therefore, your software or hardware must be able to properly send sysex messages.

We have tested the following software applications and know that they work correctly for sending sysex to the PC2 (other software that we have not tested may also work without problems):

PC Platform:

Commercial software: Cakewalk* & Logic

*Some versions of Cakewalk send the sysex information to quickly for the PC2 to process. However, it is possible to slow down the transmission of sysex information by making a change to an INI file. If you are having problems loading the file into the PC2 when using Cakewalk, please consult the online help in the Cakewalk program for details on this.

Shareware/Freeware: Windows Media Player can be downloaded at

Macintosh Platform:

Commercial software: Performer & Logic

Shareware/Freeware: MIDIGraphy 1.4.3 (older versions tend to crash w/OS 8 and 9), can be downloaded at

Version 1.07b Release Notes

1. Previously, when editing effects and changing parameters only (not algorithms), the changes would remain even after you left the editor. The proper effects would not be re-loaded until you reselected the program change (either from the front panel or via program change message). If you just left the editor and re-entered the editor without a program change, the values in the display would not match what you heard.

Now the effects will always reload when leaving program or setup edit.

2. Previously, the FXA and FXB routing display would not update when changing zones in the Setup editor unless you were on one of the FX edit pages. This problem has been fixed.

3. Previously, changing between Panel and Auto mode could cause the effects display for Panel mode to be out of synch with what was actually heard. You can try this before you update by making a new panel effect, switching back to auto, change the program, go back and re-select panel mode, then look at the effects edit.

Now when you switch from "Auto" to "Panel", the effects now change immediately instead of waiting for the program/setup change.

4. Previously, the Setup effect wet/dry and routing values were incorrect when creating an auto split/layer from an internal voice or KB3 program.

Now they all default to the programs wet/dry for each zone. The routing for zone 1 is kept, while zones 2-4 are set to FXB only.

5) Previously, the "Cancel" from MIDI receive mode would not always bring you back to the last program before entering MIDI Receive mode, but would sometimes change back to the last remembered before a mode change.

Now, if you change programs on the internal setup zone 1 channel while in MIDI Receive mode, then Cancel, the PC2 will keep new zone 1 channel program. If you change to a KB3 program on the KB3 channel while in MIDI Receive mode, it will keep the new KB3 program. Both of these only happen if there is a valid program at those locations. If you select a valid KB3 program at any point and then select an internal voice program, both of these programs will be the first program to appear when you switch to their modes. All operations on other MIDI channels will not change the reverted programs. 

6. Previously, the Global FXA->B from internal voice edit could change it's value even when not on an effects channel. 

Now the Global FXA->B from internal voice edit will no longer work if you are not on the effects channel. Instead, it will display Ch#, with # being the effects channel. 

7. Previously, entering and exiting an internal voice edit would load the effect associated with the effects channel even if the current channel was not the effects channel and the current effect was not what belonged to the program on the effects channel. 

Now when changing effects channels, the effects associated with the current program on that channel will be loaded. 

8. Previously, controllers 68,93, and 95 would sometimes get cleared when hitting the panic button, inadvertently changing the wet/dry values and programs that use controller 68. 

Now these controllers are only cleared for KB3 programs, so wet/dry values should be maintained even after pressing panic. 

9. Previously, the sustain pedal "catch" did not work properly for certain sounds. This has been fixed.

10.Previously, that use "System" tempo would sync to the internal clock but not to an external clock.

Now, these effects will also sync to an external clock. However, on some delay based effects, syncing to an external clock may cause clicks.

11. The PC2 will no longer paste effects that do not exist. (In v1.0, the way to cause this to happen is to paste effects without copying them first.) This puts an empty effect in the program or setup. In addition, if you somehow manage to get empty effects in, the system will no longer crash when trying to display the values. 

12. Compare now works when you are creating a setup from an internal voice. 

13. The PC2 now starts with program 0 Stereo Grand at power-up.

Installing files into your PC2:

Boot Block 

The PC2 boot block lets you install new software and factory setups into Flash ROM. The boot block also provides hard reset and diagnostic options. Execution of any function in the boot block may cause or require a hard reset causing erasure of the setups that you have created. To save them, back them up using a MIDI Sysex dump as described on page 4-4. 

Starting the Boot Block 

When you power up the PC2, it displays "Waiting for scanner" then displays "Please wait" after a couple of seconds. When you see "Please wait" press and release the Panic button. After the boot block message banner and version number are displayed, the first of several menu items appears on the screen. Pressing the buttons underneath the display scrolls through the menu items. Pressing the Enter button (Yes is printed underneath) invokes the menu item in the screen. 

Setting Up For a Software Upgrade 

1. Connect a MIDI cable from the MIDI Out of the computer's MIDI port or interface to the MIDI In of the PC2. 
2. Launch the sequencer application. 
3. Open the PC2E107B.MID file using the sequencer program. 
4. Start the boot block on the PC2 using the directions above. 

Installing the Operating System

1. Select Install Engine by pressing the Enter button. 
2. Select via MIDI by pressing the Enter button. 
3. Start playing the MIDI file from the sequencer. While loading, the bottom line of the PC2's display will show a message "Segment X of Y" where X starts at 1 and increments with each segment up to Y segments. If the display continues to show "Waiting for MIDI" after starting the sequencer, stop and restart the sequence. 
4. Depending on the size of the file, it may take up to 17 minutes to completely load at which point the bottom line of the display will show "Done". 
5. After you have completed loading the MIDI file, press the Cancel button twice to get back to the main boot block menu, scroll to the Hard RESET menu item, and select it by pressing Enter. Before doing a hard reset, please read Resetting the PC2 on page A-5 of your manual, so you can avoid losing any of your PC2 programs or setups. 
6. Press Yes to execute a hard reset; the PC2 will restart with the new operating system and/or setups.
