You can order custom tunings directly from C.A. Seydel Söhne web site. Go to the Seydel web site and click on the Configurator tab for more detail.

There is a catalogue of special tuning built in Harmap. But you can write your own and see the result inside Harmap. You just have to follow the few instructions.

Create a simple text file

Use your preferred text editor to create a plain text file. You can use any kind of text editor but remember: save your file as a plain text file.

The name AlteredStates is dedicated to Pat Missin (God bless him and grant him salvation) and his compiling of various tuning. See this page.

Save your file as “AlteredStates”

When you launch Harmap by double-clicking on the file, it will look for a file named AlteredStates. If it finds it, harmap will use it instead of the built in catalogue.

Follow the RULEZ!

There are few things that must be respect so Harmap can understand what you want.
