John, you're VERY welcome. I admit that I was as frustrated (if not more so) than you when I initially discovered that Yamaha (for whatever bizarre reason) designed their arranger keyboard OS (who did they hire for R&D & design engineers anyway?) to store the LEFT Voice in "STYLE" memory contents, and not with all the other voices (RT1 RT2, MAIN, LAYER, etc) in "VOICE" memory contents, as would have been expected. I was on the verge of abolishing my PSR2000 (my first Yamaha arranger) but then 'woke up' one night with the idea of creating a bogus style file of which a registration would not actually be able to call up later. I must admit it was a stroke of luck to have discovered this workaround, because if I hadn't, I definitely wouldn't be playing a Yamaha keyboard today. - Scott
