so-so
The Christmas Time track was the best of the lot.
Here's what to pay attention to, when judging:
1) Fast notey pieces, such as the Chopin etude, do NOT do piano sample assessment justice. Fast notey pieces, do NOT allow for the depth of intonation that we pianists listen acutely for. On fast pieces, almost any keyboard sound sounds very similar to any other. Get the idea? So, do slow!
2) Look for chords played in all registers, and allow them to sustain and die out. First one, let it ring and die, then another. Then do the same things with added bass octaves or jazz voicings. Occasional diminished chords, and a few slow jazz progressions, demonstrate sound dynamics that we listen for.
3) Do the above, again, this time with sustain pedal added and removed, deliberately, to allow us to hear how it sounds.
4) Pieces with other instruments do NOTHING but distract from the judgment. We are evaluating the Piano sound, not the recording/production of a song or ensemble. So why do companies do this?
In my own assessment, mostly from Christmas Time, so-so. I listen for depth, string dynamics between various velocities, and some type of sounding board beyond simple & plain.
Maybe this is a good sample for VST, I dunno. But as far as Piano samples that I am used to (pro gear hardware and keyboards), nothing to write home about.
My 2 cents.
