I edited an .HPD file in Music Editor 3. The object was a vocal in one of my songs. When I played the song with that object in Music Maker 2014 Premium, the .HPD file (the object) did not play. When I position the red playback line on it and play the song, the object plays. But when I play the song from the beginning, the .HDP object does not play. Why? I can't figure it out.
