Grand Piano Master Soundfile Clipping

This is specifically noticed on the Muse Sounds Grand Piano; it may occur on other instruments. The notes are clipping during input playback, as if they are played at 100% volume (which I believe is the way MS3 works, but without the clipping). I can turn down the track in the mixer; however, the file still clips at the lower volume. I am unsure if this is an issue with the mastered file or MS4 being temperamental in its infancy. Regular playback sounds as it should, which leads me to believe this is an MS4 issue. To avoid this, input playback can be turned off in settings, and other soundfiles can be used.
