I have this experience as well. I was frustrated with the Bösendorfer Imperial BI for this reason and when I bought the VC280 it felt worse. I decided to spend more time playing with the settings to try and work this out. Something I noticed was that the ambient preset didn’t seem to suffer from the issue, but it also has a lot of computed reverb applied, so only appropriate for a subset of music I like to play.
with the computed reverb turned off the pinging was still not an issue. This provided a clue.
What I found that does help is when you are mixing the close mics with any other mic types, if you add some delay to the other mic types in the mixing page this pinging can be silenced. It does add some natural reverb. But what I think is happening is it stops the sound of the attack from the close mic being overlayed with the sound of the attack from the other mic types.
so you need to balance how much of the natural reverb sound you are adding with the delay against reducing the pinging effect.
