NKS Fan !
I really like the Walker, but if the lite version doesn't do it for you, I wouldn't recommend the full version. It will sound and feel much the same.
And as SimpleSam says, the Signature Grand is also probably not what you are looking for if you want a close player or detailed perspective. Neither of the mics will give you that up close feel.
It does have a fantastic classical sound, but more as a "I'm sitting in the same room" feel. You can change it to sound reasonably close and have more of a player perspective, but you don't ever get the full detail a close miced piano will give.
A good comparison is, like I say in my comparison above on the Due Pianos -- they are a lot more detailed than the Signature Grand (due to closer micing), but I wouldn't call them fully close sounding pianos either.
Hope that helps.
@CGR may be able to suggest some. Craig knows pretty much everything about VI pianos. He's always the one to blame for the rest of us splashing our cash on them.
Your posts led me to this afternoon's @ Simeon Livestream, whch tied together nicely !
Set expectations properly for salient mic perpectives and room sound. Downloading now and looking forward. THX !
