Don: I assume the 'Speedy Mouse' & 'Karaoke Girl' features are working correctly on the PSR2100, right? If you go with the PSR2100 you can also 'feel good' knowing that the foot pedal triggered 'continously repeating' sub feature of 'fill self' works fine on the PSR2100, yet it 'doesn't' work on the Tyros.

I now feel for your frustration over 'Speedy Mouse' & 'Karaoke Girl' not working correctly on the 2000. I hoping my problem get resolved via a Tyros OS update and doesn't require having to buy another keyboard, like you, to get the problem addressed. Afterall, Yamaha Japan can't use the excuse (this time) that the Tyros is NOT flash ROM OS upgradeable, like the sudden turn around they did (without warning) on the 2000.

Please keep us posted with your candid evaluation of the PSR2100, and let us know if it's going to be a keeper for you.

Still LOVE my Tyros,

Scott
