Amplify the volume when two voices have a same note (for non-keyboard instruments)
I understand that when two voices have a same note on the piano the volume shouldn't be amplified, but when this happens on wind/bowed string staves, it usually means there are two instruments (or two strings) playing the same note, and in this case the volume should be amplified.
This case seriously affects the playback of the cases in which two brass instruments of the same kind, horn for example, are playing fortissimo while woodwind and strings are also playing in a big volume. Even if others are playing loudly, two unified horns can undoubtedly overwhelm them in a real orchestra, however in MuseScore playback the horns are barely heard because they have the same volume with a single horn.
I know this is only playback-affected and improvement in playback won't occupy the principal part of a notation-software's development, but I still hope that you can take note of this...
