Tied tremolo playback issue.
The tremolos on various instruments are rearticulated in every measure when there are ties. Therefore, in places where the sound of the tremolo should sound consistent, there is an undesired jolt that sounds like a sforzando.
I am a string player...Tremolos usually involve shaking the bow at a high rate of speed back and forth across the string. When we start the tremolo, we start lower in the bow and draw the bow towards the spot in the bow where we are performing the tremolo. Consequently, there is a very obvious, heavy start to the note. Usually, we do not "rearticulate" (redraw the bow) with tremolos unless noted in the music. The sound of the tremolo should remain consistent across all ties.
