What is PCG Tools?

PCG Tools is a free PC software application for Korg (c) Music workstations/synthesizers. The application is capable of handling mainly PCG files. These files are used for programs, combis and set lists, global information and more. PCG Tools is mostly a librarian, but it also has some editor functions.

PCG Tools can be used for:

  • Loading PCG files and navigating through the programs, combis, set list slots and drum kits.
  • Moving and sorting programs, combis and set list slots inside a PCG file.
  • Copying programs, combis and set list slots from one PCG file to another (not converting).
  • Edit names of programs, combis and set list slots.
  • Opening PCG files of different models simultaneously.
  • Creating all kind of lists in text, CSV, XML or HTML format showing the usage of banks, which programs are used by which combis or set list slots in various modes.
  • Creating lists of duplicate programs, combis and set list slots.
  • Creating patch lists for Cubase.
  • Moving empty programs, combis and set list slots to the end, compacting the bank(s).
  • For Kronos, editing the set list slot descriptions with use of Return characters (new lines).
  • Move timbres within a combi up or down.
  • Check some basic content of SNG files.
  • Lots more.

What can it NOT do?

  • Converting programs or combis from one model to another.
  • Editing all program or combi parameters.

PCG Tools Manual

Virtual Banks

PCG Tools can use files with virtual banks to store a lot of programs/combis. Below you can download them for your own use.

Kronos Preload Virtual Banks PCG File

This file contains the (zipped) default Preload data for the Korg Kronos (X) with 64 extra empty program and combi banks (of 128 patches each).

MS2000_MS2000 Empty Virtual Banks LIB file

This file contains a (zipped) LIB file for the Korg MS2000 with 64 extra empty program banks (of 16 programs each).

Other Files


This file contains the rules to be imported in the Program Reference changer in the Tools menu of PCG Tools. The rules can be used to use V2 (or earlier) Kronos combis and set list PCG files with a V3 programs layout. If you see this file as text in your browser, copy the contents in a file name and import the file in PCG Tools in the Program Reference Changer. For now, after loading, compress the Rules text box to press the OK button … it can take about 10 minutes to process all rules (in the next version it will be much faster).

Bug reports

If you find a bug, make sure you use the latest version. If you can stills see the bug, please send a mail to me: Bug report

Please provide the following info:

  • Description of the bug.
  • Operating system and relevant computer system information.
  • Attach a screenshot if needed.
  • Attach the PCG file resulting in the problem (I will never share PCG files received this way with others).
  • Describe exactly how to reproduce the problem.

Thanks in advance for taking the trouble; without bug reports I will probably never know of all bugs, since I don’t own all Korg workstation/synths supported by PCG Tools.
Note that the software is “almost” abandoned, so much updates won’t be released in the future. When Michel has some spare time he might consider updating the software.

Source code

The code is written in C# and is added to a GitHub repository by a friend (Dave Blickstein). Please feel free to get ideas, use it in your own non-commercial projects or build upon it (the last is preferred). Also feel free to contact me about details. Not all files are included, like documentation and test files (because some of the test files are non-free PCG files or documents under NDA).

PCG Tools Source Code on GitHub


I (Michel and also Kronoshaven.com) am not responsible for corrupt PCGs. Therefore, always make a backup first and test regularly. I do not own all models so testing has been very limited. I am not responsible for the content of the PCGs being used with the application.


PCG Tools is a free application, however the executable and the source code may not be used in projects/products which are sold or otherwise to generate money. Also my name (Michel Keijzers) must be mentioned clearly for credits when part of the source code is used. This application is not affiliated by Korg, so requests, bugs, wishes, questions etc. should be directed to michel.keijzers@hotmail.com or being posted on the main PCG Tools thread (this page).
