Kurzweil K2600 Version 2.0 Operating System Information

This zipped archive contains version 2.0 of the operating system for your Kurzweil K2600 Series Instrument, as well as the Version 2 Supplement manual. This version also requires the installation of the version 1.03 Base Objects file and version 1.0 Triple Objects file. The v1.01 Objects files for the Options (ROM blocks and Live Mode) would also be reinstalled, if they are appropriate for your instrument. You can download these files from the Downloads page on our web site - http://www.kurzweilmusicsystems.com. 

Information on installing the new OS is included at the bottom of this document.

In addition to the Triple ROM Objects file, there is also a Program Farm file with 100 extra Triple Programs. This can be downloaded at ftp://ftp.youngchang.com/pub/Kurzweil/Pro_Products/K2600/Factory_Disks/TRPLFARM.ZIP


Version 2.0 Release Notes

Version 2 adds two major new features - Triple Modular Processing and Disk Partitioning Support. Both of these features are thoroughly documented in the Version 2 Supplement manual. This file is in .PDF format, which requires Adobe Acrobat Reader. You can download this program at no charge from the Adobe web site: www.adobe.com.

An enhancement has been added to the keymap editor.  Now the CHAN/BANK buttons let you scroll through the key ranges instead of velocity ranges. Although this is a redundant control, it provides a more user-friendly way to access the key ranges while editing other parameters.  Any keymaps which have velocity ranges will now show the velocity range as a normal parameter in the keymap editor.  If a keymap has no velocity ranges, the velocity range parameters won't display.

Support for Removable Disks has been added to the Disk Macro feature. This allows you to switch disks or CD-ROMs during the loading of a Macro. Details can be found in the Version 2 Supplement manual.

In addition to the new features & enhancements, a number of bugs have been fixed:

1. In previous versions, the floppy drive could get into a state where it would not recognize known good floppy discs.

2. A Standard MIDI File type 1 import bug, in which event times might be translated improperly if a track had an end time that was earlier than the song end time, is fixed.

3. Loading of unsupported WAV formats (e.g. compressed WAVs) is now blocked.

4. A bug was fixed which caused possible display redraw problems in Disk Mode, occurring when loading a file that contained a Master Table.

5. An envelope release calculation problem, where engaging the sustain pedal during envelope release would cause the release portion of the envelope to be miscalculated, is fixed

6. AMPENV display scaling, now shows "1/1" when all envelope times are set to 0.

7. A bug was fixed in which the old Digitech effect softbutton was being displayed when editing KB3 programs is fixed. (The Digitech is not used in the K2600 - it was in the K2500.)

8. The proper Studio was not being used, after loading a file that contained both the Studio and a Master Table with an FX mode setting of Master. Now the correct Studio is selected.

9. After recording a song and hitting the Stop button, if you immediately tried to audition the new song before actually saving, notes would get stuck on when you hit the stop button again. 

10. Sending Song Select from an external device now will correctly update the Song mode display, and if the song is looping, the new song is now selected when the loop occurs.

11. It is now possible to select the Digital I/O Format when there is no sampling option installed (you would need the DIO-26 option to send digital audio).

12. A bug where the Previous page button was not always jumping to the previous page is fixed.

13. A bug was fixed in a few user dialogs, where user input was not being range checked properly, allowing bad values to be entered via the keypad.


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 K2V200A.KOS and K26V200B.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 K2V200A.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 K2V200B.KOS, then select Install System again and repeat the installation for the second part of the operating system file.

6. As mentioned at the top of this document, a new Object file will need to be installed (and the other object files reinstalled). Please see the README file included in the file OBJKT100.ZIP for details.

7. 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.
