What in heaven's name are all these "Ss" doing in naming chords? Next, the Europeans will be telling us that an eighth note "C" is played differently in Europe. "Continental chord notation" (Ss) should play no part (excuse the pun) in naming chords that have originated from pure American jazz. Let's get real here for a moment - These fancy chord names came about due to Tin Pan Alley, which is pure American. Did it ever occur to any of you that POSITION is the key (pardon, another pun) to your problem of chord recognition? Good grief! I thought we all knew this when we got these high tech keyboards. I have the KN6000 and I have yet to have a problem with chord recognition PROVIDING, I don't use pre-set rhythms. Most of my work is in PIANIST mode. I compose my own jazz bass and drums and by having the ability to arrange well, have yet to have a problem with chord recognition, due to the bass playing the right note at all times. Using the same notes and depending on your ROOT position (not always) will change the name of your chord, as well as it should. When one learns chord substitution, you will dispense with the problem of chord recognition or care what the keyboard says it is playing.
