Feature request.
I don't own this particular sample set yet, but am considering it very seriously. However this particular issue has me on the wrong side of the fence. I have to concur with the original poster that the samples for F5 are too far out of tune. So I'd like to request a feature enhancement for the player.
I note that the most recent version of the player has added the ability to EQ each individual key. I'm guessing this was done in response to user requests and/or a criticism in reviews that I've seen elsewhere.
So how about per key tuning? You already have all the technology needed in VI Pro2 stretch and render feature. You just need to apply that capability to this player and do it on a per key basis.
This way one can fix issues that are particular to their taste. I am generally in agreement with the approach taken for this sample set and that some imperfections can be a good thing. But when my acoustic piano goes too far out of tune, at least I can call a guy and get it fixed.
