Subject:Re: SK1/SK2 action and feel

It probably has more to do with who H/S thinks will be buying the instrument. The XK-3/c was intended for people who play organ and wanted an organ. The XK-1 and now the SK-1 (IMO) were more intended for people who were probably "keyboard" players or more piano focused and therefore used to notes triggering deeper. Having some notes trigger so near the top may have been a negative for them.

As I understand it (but I don't know for certain), with the Nords either the organ or the other sounds can be played but not both at once. With the SK-1 and 2 the Extra Voices can be layered with either the upper or lower organ manual.
