Ian, perhaps the reason the lack of interest in this feature (by manufacterers & players alike) has more to do with the lack of awareness (knowledge) of what this feature offers. I'm first to admit that until Dikki brought this to my attention, that this feature (which was apparently available on my Roland RA800) was even available to me. Only after reading his explaination of the 'way it works' do I now see it's terrific benefit while performing, allowing you to switch back and forth between auto-accomp arranger mode playing, and traditional piano style playing during the solo section of a song. For this reason, I think it's a terrific feature to add to arranger keyboards, Roland, Yamaha, and other arranger brands as well, and hope it gets re-instituted on Roland arrangers, and offered on Yamaha and other competing brands as well. If Roland re-introduces this on its future models as well as jazz chord type recognition, I'd certainly seriously re-consider a Roland arranger again. - Scott
