Not much that I can add to the praise that has already been bestowed upon you, you are a most accomplished performer and gifted musician my friend. And as regards the Yamaha PSR-3000 for some reason or other it was and has remained a classic among the Yamaha PSR models much as the Korg PA50/PA80 among Korg keyboards.
I recall owning a PSR-3000 for a short stretch of time in 2009 and in as far as I know there is only one song (unfortunately ) that I recorded with this keyboard, see link below.
Keep on sharing your music and thoughs with us from Russia!!!

regards
John
