How to convert .tun file to .scl the easy way

Hey microtonal gang. If you want to convert an AnaMark tun file to Scala scl (or other tuning format), here’s how you can do it using the Scale Workshop online microtuner.


Go to

Click New > Import .tun

Select any .tun file from your computer.

Click Export > Download Scala scale (.scl)

Save the .scl file to your computer. Finish.

A few more tips about Scale Workshop, .scl files and .tun files

The above method also works in reverse – you can convert a .scl scale file to a .tun file.

The Export menu gives a few other options, such as Kontakt tuning script, Max/MSP coll frequency list, or PureData text frequency list.

Scala .scl files do not preserve the base MIDI note nor base frequency. If you find that your converted .scl file isn’t in the same key as your original .tun file, then make sure you also export the Scala Mapping (.kbm) file. A .scl and .kbm used together should be in the same key as the original .tun file you imported into Scale Workshop. A .scl file used alone will assume note 1/1 is on MIDI note 60 (middle C) at 261.63 Hz. When you export a .tun file, it already contains the base MIDI note and frequency within it, so there’s no need to export a .kbm alongside the .tun.

Are your exported files not working as expected? Windows and macOS/Linux files work slightly differently. Click General settings and make sure your correct OS is chosen under Line endings format.
