From what I was lead to believe, the Yamaha samples are based upon Yamaha brand grand pianos, while some others are based upon Steinway and some other top brands. I know there is a significant difference in those two brands because of personal contact.

Now, tuning the piano involves a lot more than changing a couple EQs. There are a myriad of filters, effects, etc... that you can utilize to change the sound dramatically. There is a lady in the UK who is the absolute master of this. Eileen has tuned sax, guitar and piano sounds in many of her converted styles, then saves them as OTS settings. They're wonderful. She is one of my many heroes in this fascinating world of arranger keyboard technology.

I wish I had the playing skills to demonstrate just how great the various instruments can sound. Unfortunately, for the most part I'm a singer/entertainer--not an accomplished player. Therefore, it would really be nice to hear some performance samples from those who are great piano players using various keyboards A/B'd against a real piano and recorded using the same high-quality recording device.

Cheers,

Gary
