scott,
Not being a keyboard player, but a store owner who loves arranger keyboards because of their ease of use in making me sound good, I possed your question to a good friend of mine who bought an X1 and also had a PSR8000 before the X1. He informed me exactly as Paul Ip has informed you that the X1 does not recognize the chords you asked about. Yet I think it is very strange becasue Andy, the musician I called plays mostly big Jazz type chords and loves the way the X1 recognizes what he plays.
I also would like to clarify that the new piano sound you mention is from the super solo 8 disk set of sounds which solton sells but does not offer as a free set or as an upgrade to their stock piano. Unless your store moderates the solton club, my feeling is that they don't know what these sound disks are all about. If Solton's distributor in New York didn't tell them about these being such an improvement, they would have no way of knowing they should load these in. Also, it doesn't matter how old their keyboard is in the store as long as they keep updating operating systems as they come out. We just loaded 3.2A last week. Paul Ip, if your still using 3.0A you should be using the new operating system. Besides adding new features it also makes the keyboard work more ifficiently. Also, please check the chord recognition using 3.2A. Maybe it fixes it. I read somewhere from AJ of the Solton Club that there was one more chord recognition in the fingered mode. I think he said fingered 2.
