pianow I expect the Grand Ass piano might have a fuller bottom end, though… 😆
Seriously, I've been lurking a few days here, following the discussion. I bought Modern D within a day of its release. The hour long demonstration video broke me down.
I have a pretty sizable collection of virtual pianos, including some of the usual suspects mentioned throughout the thread (e.g. Garritan CFX, the Grandeur, American Concert D), as well as the Embertone Walker, which I don't recall seeing mentioned yet. I also have Vintage D, as well as the Meldway grand, which is kind of an obscure one.
So far, I feel like Modern D is the best VI I've used to date, and that it's a pretty sizeable leap over most of my collection. The mic positions are all useful (the hammers are my favorite), the tone is right in the sweet spot for me for a Steinway D, the sampling is pristine and even without sounding sterile and disembodied, the playability reminds me of the CFX and Ravenscroft, meaning it's a cut above all the other libraries I've tried; and Modern D is hands down the most versatile VI in my library. From bright and in your face aggressive through to smooth and diffuse (for classical, mainly), it does it all. It's a true chameleon.
Out of my collection, I would say Modern D is closest to, and consequently serves as a drop-in upgrade for, both the Grandeur and ACD. IMO, Modern D bests both at their respective strengths, while boasting more features and better playability than either (not to mention finally freeing me from the unfortunate re-pedalling glitch in the Grandeur).
Right now, my top three are Modern D, the CFX and the Walker, though the last one only makes the list because of its heavenly tone. It's one of the two worst in my library for playability and performance, and while I can get used to it well enough to get something recorded, the experience is rough. The finished render makes it all worth it, however.
Anyway, I'll close this post here. To everyone reading, free to ask me anything you'd like to know about my experience with Modern D, including any more detailed comparisons you might like with any of the other libraries I mentioned. 🙂
