The Chord Scale Generator is available for the operating systems Windows (XP, Vista or 7), Mac OS X (Snow Leopard or Lion) and Linux. Besides, you can choose between 32- and 64-bit versions for Windows and Linux.
You can use the test version of the Chord Scale Generator as long as you want. This gives you enough time to properly test the Chord Scale Generator before you consider buying the full version. In order to use the full version of the Chord Scale Generator you need an activation key.
The test version offers almost the whole range of operations. You are allowed to perform all calculations on any instrument and it is also possible to export the results in order to create your own chord, scale or song books.
However, the number of the predefined chords and scales is limited in the test version. There is only a limited number of chords and scales available and it is not possible to edit them or even create new chords or scales. Therefore, you can only perform the calculations on a certain number of chords and scales.
Note: With these restrictions, you may sometimes find the results unsatisfactory, especially the reverse calculations in order to find corresponding chords or scales for a given fingering pattern or musical notation. This is due to the fact that the program can only work with chords and scales which are already defined.
