Time estimates for whole pieces and selected sections
If a piece is loaded up to MusicScore.com and then played, times are shown at the top, indicating the total time and the time remaiining.
It would be very useful to know - even roughly - how much time a whole piece is likely to take, and also the time for sections of a piece when using the MuseScore program. Some composers and performers might find this very helpful.
I can get a fairly good idea of this by exporting pieces and sections to an audio file - mp3 will do - and then looking at the timing of the audio file, but I believe this could be estimated reasonably accurately by a process running within the MuseScore program. This could - or at least might - be a lot quicker than the audio export method.
Of course there might be other times of interest, such as the time from the beginning to a given point, or the times of each individual movement or variation in a more complex piece, but once a mechanism for basic timing has been developed it should be relatively easy to adapt it for different scenarios.
