Sound-Type-Writer (6+6)!
Click the Panel on the left. Now you should see the new 6+6-Accordion, which you can play with your Console.
It works on MacOS*), Windows and Linux !
Mount a ribbon on the left skews of your keyboard and hang it around your neck, or simply hold it between Your thighs. Now enjoy playing!
The left side bass is organized like the single-tone-rows of any Button-or Piano-Accordion:
In the circle of fifths it goes up and down.
The second column contains major or minor chords or the single thirds (see below: "Register Keys").

Even in "Single Mode" you can always access major- or minor-chords on neighbouring keys.
To accompany a melody you use chords that are located directly above each other.
Each major- or minor scale is played with the same fingering.
Once you have learned to play in one key you can play in any other as well.
Or use your Smartphone!
