Does the program work with Windows Vista and Windows 7?

Yes. The latest version of the program uses a Windows installation package to enable the program to run on most Windows platforms: Windows 98, Windows ME, Windows 2000, Windows XP (SP2 and SP3), Windows Vista and Windows 7.

The program is a 32-bit program which should run perfectly well in Windows 7 (32-bit mode).  It can also run successfully in Windows 7 (64-bit mode). The author recently tested downloading and installing Korg Z1 Editor 2004 on a brand new PC with Windows 7 (64-bit mode). The program worked fine, without any “program compatibility” issues or special settings.

However, in Windows 7 Microsoft have removed an important Windows help component used in earlier versions of Windows. This is needed to support the program’s extensive indexed and context help functions. The first time the help function is used a direct link to the Microsoft site appears so that this component can be downloaded. This only takes a minute or so, and the Korg Z1 Editor 2004 help function then works perfectly after that.

On the general question of “upgrading” to new versions of Windows, the author would advise you to retain your capability to run 32-bit programs and devices for as long as possible as some of these products - even from major vendors - will simply not run with a 64-bit machine. If you are looking for a new PC with Windows 7, try to find one that gives you a choice of running in 32-bit or 64-bit mode.

“The 64-bit version of Windows 7 is like having a hi-fi system which has wonderful sound quality but cannot play your favourite CDs”

Is there an Apple Mac version of the program?

Sorry, no. Korg themselves did produce a Korg Z1 Editor for the Apple Mac (which may still be available from the Korg web site). However, it does not contain many of the Korg Z1 utilities which can be found in Korg Z1 Editor 2004.

Does the program work with all MIDI interfaces?

The program should work well with all MIDI interfaces.

Any USB MIDI interface should be plugged in (and, if necessary, switched on) before running the program, so that it can be detected and the appropriate channels and other settings applied.

If you have upgraded your PC it may be worth checking that your MIDI interface uses the latest drivers.

Some points to watch are included in the notes on sending data to the Korg Z1 and receiving data from the Korg Z1 below.

The key point about sending data to the Korg Z1 is that computer speeds are very fast and the Korg Z1’s speed is much slower. Different MIDI setups can handle this in different ways. Version 2.1 of the program, released in 2010, accommodates this by including preset buffer sizes and delays which can be varied to suit particular MIDI interfaces if necessary.

Receiving data from the Korg Z1 is handled more easily, as the Korg Z1 transmits data at a comfortable pace for the computer. The key point here is that if the Korg Z1 is sending data and clock signals at the same time, these need to be filtered. The program applies a filter, but the effectiveness may depend on the MIDI interface. The simple solution is to set the Korg Z1 clock to EXT.

Back to top

Sending data to the Korg Z1.

You should ensure that the 3 standard settings on the Korg Z1 are in place before sending any sysex data to the Korg Z1. These are:

1 On the Korg Z1 select MIDI > MIDI SystemEX and set SysExRcv to ENA. This enables the Korg Z1 to receive system exclusive (sysex) messages.

2 On the Korg Z1, check MIDI > MIDI Basic > G Ch (Global Channel). In the program select same channel in Settings > MIDI > Output Channel. This ensures that the Korg Z1 is “tuned in” to the same channel as the program. Otherwise, it will look as if the program is not sending anything at all.

3 On the Korg Z1 select Global > Basic > Protect > OFF. This allows any banks on the Korg Z1 to be replaced by bank data sent by the program. Otherwise, the Korg Z1 will show an error message.

This last setting is not necessary if you simply want to send single patches to the Korg Z1 without replacing any of the numbered patches in banks A and B. The Sound Show and Sound Morph functions send single patches to the Korg Z1.

You can test that you are able to send data to the Korg Z1 by sending a single patch. Click on the left screen label (eg Init Patch) to show the patch editor screen and then select Send > Init Patch or simply press the F3 key.

If you have problems sending larger volumes of data (eg banks of 128 patches), this may be due to the way your MIDI interface handles the high speed of transmission and the slow rate at which the Korg Z1 receives data.

The speed of transmission is changed by breaking down the data into separate buffers and putting delays between each. Your MIDI documentation or screen options may show the settings used. In this case you should make the same settings in the Korg Z1 Editor 2004 program by going to Settings > MIDI.

If the preset MIDI buffer and delay settings do not work satisfactorily, and you do not know what other settings to use, you may want to slow down the transmission speed by trying smaller buffer sizes and/or longer delays in Settings > MIDI.

Receiving data from the Korg Z1

Before the program can receive sysex data (data dumps) from the Korg Z1, it is important that the system exclusive transmit function is turned on:

1 On the Korg Z1 select MIDI > MIDI SystemEX and set SysExXmit to ON.

The program is set up to receive MIDI data on all channels, and will normally show the last channel received. Unlike the requirement when sending data to the Korg Z1 it is not necessary to set the MIDI Input channel in the program. However, it is good practice to check that the MIDI channels are correct:

2 On the Korg Z1, check MIDI > MIDI Basic > G Ch (Global Channel). In the program check that the same channel is shown in Settings > MIDI > Input Channel.

You can use the data dump utility on the Korg Z1 to send different types of data (patch, multiset, bank etc) to the program. In that case you should set the program to prepare for the data by selecting Receive > Listen or pressing the F2 key.

However, the quickest and easiest way of receiving data is to send a request from the program to the Korg Z1 to send the type of data you want.

With your MIDI IN and OUT connections and settings in place, you should be able to instantly load the current patch on your Korg Z1 into the program by selecting Receive > Request. This will provide a list of options, with Current patch as the default item at the top of the list. Select OK.

The patch label at the top left of the Korg Z1 Editor screen should then show the name of the patch currently displayed on your Korg Z1. This means that all is fine. The patch can be explored, edited, saved or sent back to the Korg Z1 as needed.

If the patch name does not change, but instead you see messages along the bottom of the screen, this could mean that the program is not filtering out clock signal messages from your Korg Z1 and is receiving a mixture of patch data and timing messages. In this case, you should switch off the Korg Z1’s internal clock:

3 On the Korg Z1 select MIDI > MIDI Basic > Clk and change the setting from INT to EXT

Korg Z1 Editor was designed to work with either clock setting. It applies a filter to the MIDI interface to prevent clock signals from interfering with data transmission, but the filter may not be fully effective with all MIDI setups which is why this last step is advisable.

Once you have checked that the program works OK with patch data, there should not be any problems receiving other types of data. However, with banks of data one or two bytes may occasionally go astray and the program’s checking system will stop the bank from loading. This is explained more fully in the “unrecognised data” note below.

Is it possible for the program to overwrite patches on the Z1 accidentally, like some other programs.

No. The patch editor only sends patches to the Korg Z1's edit buffer. To overwrite a particular patch on the Z1 you would need to use the Z1's own write utility to copy the patch in the edit buffer to a specific location (eg A037).

If you select Send while using the bank editor, this will send the current bank to the Korg Z1. This will overwrite all patches in a bank (if the Z1's memory protection is switched off), but the program gives a warning message first and you are asked to confirm before this happens.

The Auto Send (Sound Show) feature enables you to quickly try out any or all of the patches in a bank in turn without overwriting the bank in the Korg Z1.

Inserting/deleting/moving patches in banks: tips

To insert a patch

To insert a patch within a bank (eg to put A043 Pipe Organ Full between A007 Male Ahhs and A008 Syndicate Lead) you should select all the patches between A008 and A043 by clicking on A008 and pressing SHIFT and clicking A043. Then right click and select the Rotate (+) option (or press CTRL +). This will move A043 into position A008.  A008 Syndicate Lead will become A009, A009 will become A010 and so on.

To delete a patch

To delete a patch (eg to delete A040 Rockin Bee! in the group A039 Jazz Organ, A040 Rockin Bee! And A041 Full Organ) you should click A040 to select it, and then right click and select Insert Last from the drop-down menu. A039 Jazz Organ will now be followed by A040 Full Organ.

Any number of patches can be deleted in this way. It is only necessary to click on Insert Last once.

Patches are not actually deleted from a bank by doing this, as this would leave a bank with less than 128 patches, but the effect is much the same. Patches are moved to the end of a bank. They can be left there and ignored, or easily replaced by better patches.

To swap 2 patches

Click on the 2 patches and select any of the 4 rotate options in the (right button) popup menu (or simply press CTRL + or CTRL -).

To undo the swap just select the same rotate option again or select Undo or press Ctrl Z.

To move a number of patches around

Click on the patches and select rotate+ in the (right button) popup menu (or press CTRL +). If you want to undo the last move just select rotate- or select Undo or press Ctrl Z (or press CTRL -). When each patch is in the position you want just click that patch to deselect it. Carry on until each patch is in the position you want.

If you want to move the patches by more than one position at a time then you can use rotate++ in the (right button) pop up menu. This moves patches forward by 50%. For example, if you have selected 8 patches it will move them forward by 4 positions. To undo you should select Undo or press Ctrl Z.

To move a number of patches around in an ordered way

Click on those patches and select one of the sort options in the (right button) popup menu. To undo you should select Undo or press Ctrl Z.

To reverse the order of a number of patches

Click on the patches and select rotate-- in the (right button) popup menu. To put the patches in their original order just select the same rotate option again or select Undo or press Ctrl Z.

All the options shown above (apart from Insert Last) only affect the patches you select (highlight). You can use the 4 rotate options and the 6 sort options in any combination to put patches in the positions you want. All other patches remain unaltered.

To move a number of patches to the start of the bank

If you want to move only the patches you select and the patches at the start of the bank which they replace, select Swap First in the (right button) popup menu. To undo the swap just select Swap First again or select Undo or press Ctrl Z.

The new Swap First and Swap Last tools simply swap the patches you select and the corresponding patches at the start or end of the bank. All other patches remain unaltered. With this option the start or end patches which you have just swapped are highlighted in their new positions to make it easy to identify them.

The options Insert First and Insert Last (the same as Put First and Put Last in earlier versions of the program) are rather more powerful. Insert First will put the patches you select at the beginning of the bank and move all other patches back, which changes all patch numbers in a single operation. The patches you selected will be highlighted in their new start or end positions.

Insert First and Insert Last can be very useful if you have a bank which you are free to add to and change as much as you like. If you are not sure whether you want to use Insert First or Swap First you can try them out and select Undo or press Ctrl Z if you change your mind.

I loaded a multiset into the program but it only showed patch numbers. How can I show multiset patch names as well?

Korg Z1 multisets contain only bank letters and patch numbers. On the Korg Z1 these numbers are converted into patch names using the currently loaded banks. Similarly in the Korg Z1 Editor program these numbers are converted into patch names used in banks A and B if these banks are loaded.

There is a way to show multiset patch names in the program even if banks A and B are not loaded. When you load bank A or bank B into the program you can select Bank > Map New when each bank is displayed. You only need to do this once. This stores a list of bank numbers and corresponding names in the program's data folder. After that multisets and multibanks loaded in the program will show the names of patches as well as the bank letters and patch numbers, even if banks A or B are not loaded.

Not only can you display the patch names of each multiset on screen. You can also use the print or save list facilities in the program to print out or save lists of each multibank, showing all the patches in each multiset in each multibank.

I use multisets with my sequencer, and don't want to change or delete any of the patches which the multisets use. Any suggestions?

You could print a list of all the patches used by the multisets in each multibank and then scan this list before deleting any patch. You need to enable your multisets to show patch names (as explained in showing patch names in multisets above). Then you just load a multibank and select File > Print.

However, to save having to refer to the list each time you move or replace a patch it may be worth doing a one-off reorganisation. You could put all the patches used by multisets at the beginning of bank A or B, sort them alphabetically for ease of reference and then use the remap tools including the new Show Remap utility.

For convenience, the 77 patch names used in the original Korg Z1 multisets (factory presets) have been grouped together here, showing their original bank and patch numbers. You can download the list by right clicking one of the links below (and selecting Save Target As...)

Alphabetical list of multiset patches (1K)

Numerical list of multiset patches (1K)

You can even download (below) the Korg Z1 factory banks A and B with these 77 patches changed from User Group 1 to User Group 2. You can then use Bank > Find Patches > User Group = GROUP2. All the multiset patches will be highlighted. Also, if you send these banks to the Korg Z1 all these patches will show User Group 2 instead of User Group 1. (You could, if you wish, change the name of User Group 2 on your Korg Z1 to a more meaningful name eg Multiset Patch)

Bank A with multiset patches changed to User Group 2 (83K)

Bank B with multiset patches changed to User Group 2 (83K)

Ian Clark adds: On my own Korg Z1 I then moved all these patches to the beginning of bank B, using Put First, Export/Import (bank) and Sort by Name in the bank popup menu. After moving the patches I used the Bank > Create Remap and Multi > Remap Multibank tools to remap both multibanks. All the original Korg Z1 multisets in multibanks A and B work correctly using their original patches, even though all the patches are located in bank B (at locations B000 - B076). By doing this I can now add, delete and move patches in bank A as much as I like without any risk of affecting any of the multisets.

I get a “Missing remap text files” message when using the Create Remap function

The Create Remap function uses 4 text files showing lists of patch names and bank numbers for the original banks (oldA.txt and oldB.txt) and lists of patch names and bank numbers for the current banks (newA.txt and newB.txt). These text files can be quite useful on their own.

These files can be produced by the Bank > Map Old and Bank > Map New functions. Where they don’t exist, they should be created when using the Create Remap function. In earlier versions of the program one of the files might not be created, and the above error message appeared. This has been corrected in version 2.1.221 of the program (Feb 2010).

The Create Remap function links these 4 lists together into a conversion list (the remap). This can be seen on screen, with different display options, and all or part of the remap can be copied into sequencer programs that use lists of patch names and numbers and remapping functions.

The remap can also be quickly and easily used by Korg Z1 Editor to change all or any multisets so that they continue to use the same patches as before.

Korg Z1 Editor gave me a "File may be non-Z1" message when I tried to load a bank file created with a Korg Z1 Sysex merge utility. The file loads OK into a sysex dump program. Is it safe to send it to the Korg Z1 with that program?

If the merged file was created by Pete Kvitek's merge utility then it is probably safe to send it to the Korg Z1 using a sysex dump program. Pete is well respected in Korg Z1 circles and his utility has been around for quite some time.

The file created using the merge utility is not actually a Korg Z1 bank file, using the Korg specification for such files. That is why the file will not load into Korg Z1 Editor. The merged file is made up of individual patch files joined together. When sent to the Korg Z1 it treats it as a succession of requests to overwrite individual patches - not as a bank file. Sound Diver also uses this type of bank file.

Sysex dump programs and sequencers will happily load files which vary in size and content from the Korg Z1 specification, as they do not check the integrity of the data. This can sometimes cause problems. It is always safest to check the file in an editor program first.

If any Korg Z1 file cannot be loaded into Korg Z1 Editor, and you are doubtful about sending it to the Korg Z1, you are welcome to send it to the IAX Software helpline to check it to see if it can be converted into a useable file (or files).

By the way, the Bulk Import (to Bank) utility provides a fully flexible and controllable tool for merging patch files to form new banks. The Extract to File tool already provides a fully flexible and controllable tool for splitting banks into component patch files. All files created with these utilities conform to the Korg Z1 specification.

I sometimes receive "unrecognised data" messages when sending banks from the Korg Z1 to the program. This does not happen when sending single patches. Why is this?

Single patch files are small, and sending and receiving them is handled easily. One of the Korg Z1 Editor 2004 beta testers sent 256 patches from the Z1 to the program one after the other, and checked them, with 100% success. This is typical performance for the program.

Larger data is transmitted slowly by the Korg Z1, and is more reliant on uninterrupted, glitch-free operation by the Z1 itself, MIDI connections, MIDI interfaces, the various MIDI software components and the PC operating system. Occasionally there may be a problem where one or two bytes are "lost". The program will show this as "unrecognised data", rather than try to load and display corrupted data. This reflects the program's checking system, which is a feature of good editor programs. Sequencer programs which handle sysex dumps, or general purpose sysex dump programs, will happily load the data without checking.

If the "unrecognised data" message appears, data can simply be retransmitted from the Z1. In the experience of the author and the beta-testers it is rarely necessary to retransmit data more than once.

Technical note: Although there could be a number of reasons for "losing" data bytes, the most likely - and consistent - explanation is a one-off resizing of the computer's MIDI input buffer during MIDI transmission which interrupts the processing of the incoming MIDI message.

If the "unrecognised data" message appears often you should refer to Help > Contents > Troubleshooting > Check List > Problems receiving from the Korg Z1 or contact the helpline here.

It looks as if the Bulk Import tool can only replace a continuous sequence of patches in a bank. Can it also replace selected patches dotted around a bank without affecting any other patches?

Yes. The File > Import to Bank tool on its own was designed to directly replace a sequence of patches starting with the bank patch you select (eg 013, 014, 015, 016, 017, 018, 019 ...). However, it is possible to directly replace a number of separate bank patches (eg 003, 017, 045, 068, 088, 089, 102, 116 ... ) if you use the File > Import to Bank tool in conjunction with the existing Export/Import (bank) tool (which swaps patches between banks).

Suppose you have 8 separate patches in bank A that you don't like and want to replace them directly with 8 new patches that you have just downloaded. Here is what to do:

1. load bank A and then select Bank > Swap Banks [to create a temporary Bank B]

2. load bank A again [this will be the active bank A]

3. select File > Import to Bank and select the 8 patch files you wish to import in the file list. Select bank B, select patch no B120 in the Select start patch to overwrite box and click Import

[The 8 new patches are then imported as B120 - 127, the last 8 patches in bank B. If you wanted to import 48 patches you would select patch no B080 rather than B120. B080 - B127 = 48 patches]

4. click Done

5. in bank A, click on the 8 patches that you want to replace

6. right click and select Export/Import (bank) in the popup menu.

[You will be asked to confirm that you wish to replace these 8 patches with the last 8 patches in bank B]

7. click Yes and that's it!

You can now send your new bank A to the Korg Z1 (and save it on the PC as well). You might also like to print out a copy of your latest bank A patch list (File > Print).

Bank Sort and Undo: tips

There are 10 sort options, which can be applied to a group of patches or an entire bank.

Sorting a group of patches

Firstly select the patches you want by:

a. using the Bank > Find Patches menu option; or

b. clicking the first patch and pressing SHIFT and clicking the last patch to make a continuous selection; or

c. clicking each patch directly.

Then click the right mouse button and select one of the 10 Sort [...] options in the popup menu.

Sorting an entire bank

There are times when you will wish to sort an entire bank. You may want to do a reorganisation of your banks, or to produce different versions of your banks to keep on a memory card with all the patches sorted for ease of reference. To sort an entire bank you should go to the main menu and select Bank > Sort by ... and one of the 10 sort options.

Sort and Undo

The new Undo feature opens up additional possibilities for using the sort options. For example, you can now do a quick, reversible bank sort to check for duplicate or similar patches. If you have used another editor program that moves patches by using "drag and drop" it is possible that you may have duplicate patches. Getting rid of these patches makes it easier to fit new patches into a bank.

Duplicate patches: you can sort alphabetically using Bank > Sort by Name to check if you have any duplicate patches. Duplicate patch names will appear together. After you've checked, simply select Undo... at the top of the Bank menu or popup menu (or Ctrl Z) to put the bank back to its original order.

Similar patches: you could do a multiple sort (eg OSC1, OSC2 etc) to identify patches that may be the same or similar, even though the names are different. When done, select Undo... (or Ctrl Z) the appropriate number of times to put the bank back to its original order.

Sorting patches by OSC1, OSC2, FX1, FX2, Filt1 and Filt2 will put the same patches next to each other and will tend to put similar patches next to each other. If you select these sort options in reverse order you will have a bank sorted by OSC1, then sorted by OSC2 within each OSC1 block, and so on.

You could send these sorted patches to your Z1, and listen out for any that sound like duplicates or candidates for removal. To do this you should select the patches you want to send and then select Auto Send (Sound Show) in the right popup menu.

If you want to do an exact check on 2 (or more patches) that seem like duplicates you can put them into the patch editor (Put in Patch Editor in popup menu) and then select System > Compare Last. This will tell you if the last 2 patches loaded in the patch editor were identical. If it is only parameters 1 to 16 that are different, the patches are identical apart from name.

Exploring the Korg Z1 MOSS: tips

The Korg Z1's Multi Oscillator Synthesis System (MOSS) has amazing capabilities. Many synthesisers use just 1 oscillator type to generate sounds. The Korg Z1 has 13 different oscillator types, many of which can be combined. This makes it a very powerful, but also rather complex, synthesiser.

The best way of understanding each oscillator type is to select and compare patches produced using each of the oscillator settings. The Super Find and Auto Send (Sound Show) tools make this particularly easy:

1. load bank A or B (or both) into the program

2. select Bank > Find Patches ( or Ctrl F)

3. in the Find by Type box select OSC1

4. select one of the 13 oscillator types in the drop-down list

5. click Find and then Done. All the patches which use this oscillator type as the primary oscillator (OSC1) will be highlighted in the selected bank.

6. right click on any of the highlighted patches, and then select Auto Send in the pop-up menu. When you select Start on the Auto Send screen the patches will be sent to the Korg Z1 in turn. You can play them as they are sent, or hear them play automatically using the Sound Show option.

As well as the preset Korg Z1 banks A and B, you may have other Korg Z1 banks. In order to check all of your patches which use any given oscillator you would need to check each bank separately. To avoid this, you could first set up a library folder with all your patches sorted by oscillator type. You would only need to do this once, and then you can add to it as necessary:

1. select Settings > File Names and check that the Patch name format box is set to oxx patch name. (This will automatically save patch files with the primary oscillator number followed by the patch name)

2. load a Z1 bank into the program, and select all 128 patches by clicking on the first patch and pressing SHIFT and clicking on the last patch

3. click the right mouse button and select Extract to Files in the popup menu

4. select (or create) the folder you wish to use as your library folder, and then click Save. The 128 patches will be saved as 128 patch files in just a few seconds

5. when you have done this for each of your banks, you will have a folder containing all your patches sorted by primary oscillator type:

o00 Standard OSC

o01 Comb Filter OSC

o02 Variable Phase Modulation OSC

o03 Resonance OSC

o04 Ring Modulation OSC

o05 Cross Modulation OSC

o06 Sync Modulation OSC

o07 Organ Model

o08 Electric Piano Model

o09 Brass Model

o10 Reed Model

o11 Plucked String Model

o12 Bowed String Model

The author's patch library, containing 772 patches sorted by oscillator type and then alphabetically can be downloaded here:

Korg Z1 patch library: 772 patches (0.35 MB)

Having created a patch library folder you can then use the File > Import to Bank and Auto Send (Sound Show) tools whenever you wish to check out a group of patches with the same oscillator type:

1. load any bank into the program (as a temporary bank)

2. select File > Import to Bank to put the patches you want from your library folder into the bank

3. highlight these patches, by clicking on the first patch and pressing SHIFT and clicking on the last patch

4. right click on any of the patches, and select Auto Send in the popup menu.

Do you have any plans for future upgrades?

With the release of version 2.1 of the program, there are no plans for any early upgrades. This very much depends on comments received about current features and suggestions about new or enhanced features. All feedback is very welcome.
