Tempo and Playback Issues
Whenever I change the tempo, at random times, MuseScore will not change the playback tempo to the tempo I have specified. Usually closing the program and re-opening it will temporarily fix it, but it keeps occurring and gets frustrating. Also, sometimes MuseScore will not play some instruments for their full length. For example, I was composing a marching band composition in 3/4 (in the key of C Major), and I had written a measure where the tuba plays a C natural (C2) for the entire measure, so a dotted half note, and the sound cut off around the one and a half or second beat of the measure. Which not only makes the playback different from what's written, but also sounds weird when the lowest bass voice releases half way through a measure, but the higher bass voice, tenor, alto, and soprano voices continue on. I will be including the file of the piece, so that it can be determined if it's just a corrupted MuseScore file, or bugs in MuseScore.
