Hello, Simon. Thank you for your advice.
Unfortunately I haven't got my answer here or anywhere.

I "Toned" down ( to -9) but it didn't work at all.
Also the overall sound becomes muffled, so I don't like it.

Next I tried BB Five Band EQ. This is better but still hiss noise.
Same as TDR Nova.

Question with these EQ... Can I apply only to some bars (tempo changed bars only)?
because I have no issue with the sound before the tempo change and after it goes back to the normal tempo.

Regards,
Jazzutako
