Thank you for your replies, however i am still not getting the desired effect. lets use room grand 1, found here (edit: just noticed it's created by you, BradMZ, Thank you for that!). To hear the difference in timbre: 1. Play middle C 2. Push the pitch wheel to +2 3. Play Bb on the keyboard Same C, but slightly brighter. I am not getting this effect with Edit>stage setting>zone edit>mixer edit>coarse tune. maybe there is another thing causing this, such as key values affecting parameters? I want to fix the pitch at +2 and the keyboard output to -2, so i can have the new timbre, but C is still C etc. Thank you!
