Kurzweil K2600 Version 1.13 Operating System Information

This zipped archive contains version 1.13 of the operating system for your Kurzweil K2600 Series Instrument. This version also requires the installation of the version 1.03 Base Object file. You can download this file from the Downloads page on our web site - http://www.youngchang.com/kurzweil. The v1.01 Objects files for the Options (ROM blocks and Live Mode) are still current. Of course, since all objects must be installed together, you must reinstall the v1.01 Options Object files (if needed) when you install the v1.03 Base Objects file.


Version 1.13 Release Notes

This version contains one new parameter, Song Control, found on the COMMON page within the Setup Editor. This parameter has two possible values: Song or Setup. This parameter works in conjunction with the Song parameter on the COMMON page. If a Song is called up from within the Setup, if the Song Control parameter is set to "Song", the song plays back exactly as recorded. If Song Control is set to "Setup", all events except for Notes are filtered out when the Song is played.

This parameter has been added for use with the preset Groove Setups in the K2600. The K2600 contains a number of preset songs, found in the 0s bank. Many of these preset songs originally contained no program change or controller messages - the programs and controller settings were called up by the individual Groove Setups which were designed to use these songs.

Although the songs would play perfectly in the context of the Setup, if you went to Song Mode, these songs could sound strange since there were no program changes in them - the sounds you would hear would be whatever happened to currently be assigned to the MIDI channels in those songs.

To avoid potential confusion, and to allow users to use these songs themselves for their own purposes, we have added program and controller info back to these songs in the version 1.03 Base Objects file. However, this could cause a conflict between the program changes in the songs themselves and the program change messages being sent by the Setups. So it is for this reason the Song Control parameter was added, adding the ability to choose either the Song or the Setup to be in control of selecting the programs and other controller info.

In addition, this version contains a couple of bug fixes for Song Mode and the Diagnostics.

The complete procedure for installing the operating system is included in Appendix A of the K2600 Performance Guide. For your convenience, here's a summary of the procedure:

We always recommend that you save any RAM objects to disk before doing any OS or Objects installations.

1. The Operating system is in two parts. Copy the files K2V113A.KOS and K26V113B.KOS onto two DOS formatted floppy disks.

2. Start the K2600.

3. Press and release the Exit key while the "Please wait..." message is displayed. This brings up the K2600 Boot Loader.

4. Insert the floppy with the file K2V113A.KOS, then select "Install System" from the K2600 Boot Loader to install the new operating system. Follow through the dialogs to install the file from floppy.

5. The Boot Loader finishes installing the first file and returns to the Boot Loader screen with Run System hilighted. Insert the floppy with the file K2V113B.KOS, then select Install System again and repeat the installation for the second part of the operating system file.

6. When the installation is finished, choose "Run System" from the Boot Loader.

While you won't normally need to reinstall the operating system, you should still put the disk in a safe place, just in case you may need it again.

Note: you can also install these files from a DOS or Kurzweil formatted SCSI disk. When the display asks which device you want to install from, change the parameter to the appropriate SCSI ID. You can only install files from a SCSI disk which is 1 gig or smaller.

We recommend performing a hard reset after installing and running the new system. Choose the Reset soft button from the Master page.
