I think that Roland chord recognition is the best ever (they have also some patents about it).
For sure I'll report your requests and I hope they'll consider them.
About G70 piano I can confirm what RF says: it's really impressive and outstanding, but many other new sounds are really cool too.
There is also plenty of features for midi file playing and one man band applications.
I suggest everybody to check it carefully and personally, and verify if it meets your taste and needings.
