I am hardly a pianist, but still I love to play and learn/transfer anything I do learn or know on guitar (54 years "pro" yesterday!) or mandolin, to piano.
I found this thread very interesting. I still use my trusty old K2500 for piano, though I have added xln's collection ($29), NI The Giant, the IK Alan Parsons Imperial Grand and then there are some others, like in DSF, GPO5, and TruePianos Amber. I am always messing with the EQ and "room/reverb", trying to achieve the sound I heard (or thought I heard!), whenever I got to try a real Steinway D.
I worked with a woman for a "one off" concert, and got to try her Bosendorfer a few times. She went to Germany to buy it and had it shipped back to Michigan, saving thousands and thousands of dollars. It was extremely nice, but I seem to "hear Steinways", still! LOL
Though I've thought about Ivory, I haven't taken that plunge, yet. Most recently I've thought about the Waves Rhapsody, Sonivox and after Craig Anderton's review in the latest Music + Tech, the Rapture Pro SampleTekk.
I can tell that it's like "casting" an acoustic guitar for a part..... "this one? Nope" ?that one? Nope" "how about this one?" etc till you find one that suits the track/part/arrangement, etc.
Thanks for the thread guys. It's been informative. Konradh; I hope you find that elusive "twinkling air".
