Kudos again,

Also, intriguing microphone placements.

In fact, I used the Standard Sound Recording of the specified Pianoteq presets (only with a pan offset as shown)
I also did a second test with only the 6 most recent presets:

(ptq prelude without specific setting, all instruments at the same level)
Reaper pan setting:
- 90% left: Grotrian Concert Royal
- 68% left: Steinway B Prelude
- 42% left: C.Bechstein DG D 282
- 11% right: K2 Prelude
- 68% right: Steingraeber E-272
- 90% right: Ant.Petrof 275

Having recently received my new Clevo laptop with a core i9 9900k processor, I tried a little stress test with the version Pianoteq 6.6.0 pro.

With the latest Reaper x64 version: 8 Pianoteq Vsti Concert piano at 96khz/32bit with maximum polyphony each
in real time with the same keyboard input.

Result: no audio problem in live usage:

Chopin Ballade 4 op.52
International Piano e-competition recital round.

This .mp3 version proposed on the forum does not allow to perceive completely the instruments (ex to 3'30 '- 3'40'), the reproduction in .flac 96k is a little more precise on such a passage; link: http://dl.free.fr/k66JDOINW (98.5 MB)

In any case, this recording on 8 virtual piano is only a test, initially intended to verify the possibility of running multiple instances of Pianoteq 6 with a Core i9 9900k processor on motherboard Clevo. (Laptop). link on the configuration: https://www.3dmark.com/pcm10b/653932

In practice, it is possible to use only 2 to 4 instances of pianoteq at 96k internal sampling before the fans begin to blow audibly. (with one or two instances, the laptop remains totally silent). With 8 instances at 96k internal simpling, with no polyphonic limit (in this example, up to 80 notes per instance in this ballad no 4), it is still possible to play live without any problem (except the noise of the fans)

Of course, the 8 instruments of Pianoteq could certainly be much better developed with a trimming deeper than this quick assembly.
One of the questions I wanted to try to answer (in part) was also what all pianoteq piano models have in common, also comparing them with real acoustic models:

Watch from the 7th minute of the video, the beginning of this 4th ballad on Yamaha CFX, Bosendorfer Imperial then Steinway D274. with the same pianist and the same recording conditions, but "unfortunately" with only one instrument at a time played by the pianist ...
