Stretched/Equal tuning didn't work for Komplete pianos

ctrlok

I found tunning can be changed in instrument options for Maverik and Grandeur and other pianos; still, after changing tuning from stretched to equal and back, I heard no difference.

Then I placed a tuner after instrument and tried to switch between tunning options — nothing changed (at least for C4,C#4,D4... and so on till C6)

I tried this in studio one, and then again in standalone Komplete for different NI pianos without any success.

Is it working for any of you? Or it's just a bug?

If it's working for you — please check with tuner is there changing in frequencies? For some notes (C4# or E4) difference should be quite significant (2-4Hz)
