So I wrapped up my 1st round of testing and playing with the Pianoverse Steinway and Bosendorfer models. Also these 2 models are unmistakably 12 dynamic layers. These two are definitely my least favorites out of the bundle.
I'm a huge fan of the New York Steinway, but this one is not for me. Some might call it warm, but to me it's muddy and lacks the treble I expect from a Steinway. Compared to the VSL it sure has a lot of low-end and body, but it misses clarity. If I EQ a bit of 250 cycles out it becomes a bit better, but I have a hard time to really make it sound good to my taste. At the high dynamics it starts to sound great but then you're also out of dynamic layers
It also feels very uneven to me, and E5 sounds completely filtered when played at low and medium velocity. If you play at very low velocities, all you hear is some low percussive sounds instead of a piano tone. It stays that way even if I remove all the key noises. Might be the model they sampled though.
I can imagine some people might really like it for cinematic and very intimate stuff, as at low velocities it almost sounds like a felt piano to me.
The Bosendorfer sounds good, as we all have been able to hear from the demos from
@CGR though I already fell in love the the Tube mic on the VSL. The B280 has a bit more warmth in the lows, the VSL more presence in the upper registers and also a bit more clarity in my opinion. Though at it's price point, the Pianoverse Bosendorfer is a hell of a deal compared to the VSL 280VC full edition (needed to get access to that Tube mic).
I do not get though that IKM did not want to tell us that they sampled 12 dynamic layers. Alicia's keys has 12 layers, AcousticSamples C7 has 9 layers and they both are deemed very good. There's more to a realistic piano sound than the dynamic layers which you can mask in a production with a bit of editing (in a lot of cases).
I also do not get why they chose to make the mic's switchable instead of blend-able.
What's unique is the extreme dry recordings. The tone, note attack and releases are really good. The way they added the effects and generative reverb is a nice bonus for creativity. Although you can not blend the mics, it does give you an additional color.
It's highly likely that I will pick up the Yamaha U5 (Royal Upright Y5) and maybe the CFIII.
