I would never artificially make a grand piano mono....
Additional information to my post above:
It actually shows once again how pointless mixing tips are if you don't know the source material. A sampled piano can
a) either sound completely “dry” and have the lowest notes on the far left of the stereo field and the high notes on the right.
b) It can be recorded sideways, with some space
c) It can be recorded with room microphones
d)
e) you can perhaps create a combination of all microphones...
Of course, you can only give tips once you know the original sound.
When civilizashum says he would never make a piano mono, I didn't say that...
I assumed a dry piano sound (example dry)
If you add reverb to this and push the piano down a little, the low notes will still sound on the left and the high notes on the right. This causes irritation for the brain because it has never heard anything like it in real life (this cannot be true). Now comes my suggestion to reduce the stereo width a little (not mono!).
Listen to all the examples - also together with strings and preferably in headphones. A 100% wide piano may sound great, but natural is different.
Even civilizashum reduces the stereo width when using MIR. I don't think he's pulling up the piano on his virtual stage from the far left to the far right.

So listen to
Piano-Mix_pur_wet how far the low notes will still sound on the left and the high notes on the right. The
Piano_Mix_wet_50%stereo fits much mor better to the acoustical distance.
Same with additional strings...
That's about the point narrowing the stereo-width (not to mono). But once more: it depends on the source material...

Goldblattxo, you see, if you want us to help you, a short example of the strings and of course your piano would be very useful. Otherwise, advice can even be counterproductive.
