Playback on individual note selection

Hi,

I am working an a choral piece where part of the score is written in pianissimo. When I select a note to start playback, it will shout it at me in mezzaforte instead of adopting the pianissimo of the whole section. It then often but not always, doubles the insult by not playing the actual selected note when I press spacebar for playback, but instead starts on the next note in the bar.

It is really difficult to work with, but I don't want to turn off selected note playback as I want to be able to hear it, just at a sensible volume.

Is there a work-around or a way to control the selected note volume? At present I am trying to remember to select dynamics, lyrics or articulations when I don't want to hear the note, but it's a faff.

Any help will be much appreciated

Thanks

Philip
