Ok, here's the latest in the continuing saga of: "The Mystery of the Left Wing Freeze"

It appears, after my telephone discussion with Denny, that both the Yamaha 9000pro (current OS) and also the PSR2000 (at least on the older OS version), that the left voice setting is stored in Registration Memory Contents in the 'style (acmp)' section, and NOT in the more expected location: 'voices' section, where the Main (rt1), Layer (rt2), and Left voices are stored. This goes beyond conventional wisdom, but hey, I guess Yamaha is not conventional (how boring), but because of this, it IS possible (as Denny attests) to freeze 'just the left part' by simply selecting (mark the checkbox) the 'style (acmp)' in the Freeze Window and turning ON the Freeze button. I tried this on my kb and it WORKS on the 2000 too. YIPEE What's interesting is that even though you are supposedly freezing both the style (acmp) and the left voice, you effectively really only freeze the left voice, because when I then select another style from the Style section, the style changes (along with new Main (rt1) and Layer (rt2) voices, but the Left parts remains unchanged. I'm of course estatic that it is possible to freeze the left voice part on both my PSR2000 & 9000pro now. I wonder why this was not covered in the manual whatsoever !

I had thought (just rumor?) that the PSR2000 newer OS version moved the Reg Memory Contents: Left Voice storage location from being stored in the 'style (acmp)' section to 'voices' section. If that really is the case, then I'd suspect that the left part freezing would not be possible on later PSR2000 models. Perhaps this OS update change never really took place?!

Anyway, I'm beginning to feel a lot more confident (crossing my fingers) that the Tyros will work the same way as the 9000pro and PSR2000 (my OS version) in this regard. If so, I'm definitely going with a Tyros, a logical upgrade from the PSR2000 (though still a terrific keyboard which I'll keep as a secondary kb for small venues where built in speakers are required).

Thanks to Denny Starry for helping me solve this issue, and helping me finally figure out that the PSR2000 does support freezing just the left voice in the SAME way the 9000pro does. Life is good (for today).

OK, Danny, gonna take my hand out of the freezer now. ouch ! Freezer burn [img]http://www.synthzone.com/ubbs/biggrin.gif[/img]
