ah, my inclination to express my knowledge about what is an open trade secret is overwhelming my desire to keep it.
the secret to the newman piano sound is eq - not even light touch. put a high cut filter all the way down to about 400-500 hz on close mic'd piano. ivory even has settings that will emulate the sound. oh and plenty of warm reverb.
ivory is probably ideal for this, and the steinway is seriously lush.
but you can even get the effect pretty well with logics own bog standard yamaha samples, but ivory will give you that extra "yumminess" for want of a better word.
I have played the piano live on sessions to create the effect and i am always told to play a little louder, believe it or not.
if you are interested i have on my ftp site a rough demo for a production i will be starting on soon that uses ivory steinway and eq'd into newman territory. not all the way - i wasn't aiming for that amount of intimacy, but it gives you the idea.
you can get it here (piano comes in after duduk opening)
