I've been struggling with Pianoteq recently.
After listening closely, I have noticed that the keys make an annoying, tremelo or vibrato sound. It is more pronounced on some keys than on others.
I recorded notes in the area of the keyboaard where it bothers me the most. It is most pronounced in the final 4 notes of this series. Here it is:
If any of you have ideas on what causes this, I'd appreciate your observations.
I thought that it might be the "Unison Width" setting, as, on a real piano, the unisons can cause "beats" if they are not right. But, the unison width setting is on 1.0, which is the default. And, moving the setting either direction does not affect the sound.
Thanks for your thoughts.
