Hmm! I think I have got to eat a large portion of humble pie.
I have checked with the Ketron (Italy) site and it has issued 5 firmware updates for the SD7. I have not been able to check but my other board, Tyros 5 has not received as many and is an older board.
However, that maybe because is hasn't needed as many. The one thing that is a problem for me is the sound of the chord changes. I have tried changeing easy 1 finger 1 etc. and have settled on finger 2.
I can only play 3 fingered chords so perhaps this is the trouble but on the T5 the chords play faultlessly.
I cannot explain what the problem is because I don't know but many (not all) sound wrong. Perhaps this is what Country Man is referring to in his previous post.
I hope it can be sorted because as I said earlier, the sounds and styles really are exceptional
Note for A.J. I cannot accommodate an SD9 because of width restictions where the two boards are installed.
