The first note is altered in loop playback
MuseScore 2.0.2 / Windows7
1) Open this file: loop.mscz
2) Select the second measure
3) Hit "Loop playback" in the tools bar
4) Start playback (turn up the volume so that the effect is more obvious)
Result: the sound of the C eighth note is altered. One can hear a parasitic noise, a kind of "plop"
- Former issue: same result with a nightly of May 2014.
