Chord TX Mode gemerate or other solutions

Hello Resonotter,
thanks for your help. I’ve thought about it again. I have 4 rows on the accordion, and each row represents major, minor, diminished, and dominant seventh. This means there are only 4 C chord possibilities, which can then end on C3, C4, C5, or C6. All other constellations do not exist for C. Could you take a look at my program and my list and confirm this for me?
