Hi Diki
A standard Wersi has 3 different level settings of chord recognition, (Plus modes for if you are using a Pedalboard) to allow it to adapt to different techniques, however if you add the OAA (Open Art Arranger) software then this has multiple chord recognition systems (Automatic and manual) that no other arranger/organ can match. (Every single chord recognition system of any arranger/organ is available to the user)
Hope this helps

Bill
