MuseSounds Flute Harmonized Eighth Note Run Has a Playback Echo That Builds Over Time (intervals on one Flute staff don't sound straight)

Issue type

General playback bug

Bug description

In a run of eighth note intervals on a single flute staff at any tempo, eventually a noticeable "echo" of each note will be heard before the next note, effectively doubling each note played. This does not occur with quarter notes at higher tempos, or sixteenths at slower tempos, just eighths at multiple tempos.

Steps to reproduce

1. Open New Score
2. Choose Flute (just 1) as an instrument (occurs both in ensemble score and solo)
3. Write a line at least 4-5 measures in length (4/4 or 3/4, bug replicates in both) of eighth notes of any intervals in a constant run, both on Voice 1 (akin to a Piano score)
4. Set tempo to anywhere between eighth-note = 80 bpm to quarter=160 bpm (tested range) and listen to playback
5. By the last few bars, a noticeable reverb or echo should be heard; at slower tempos it sounds swung, faster tempos just like an Eighth Through Stem tremolo.

The Video file has an audio export of the screenshot above, where the error in question can be heard a couple of bars before the 160bpm tempo change, and again by bar 3 of the new tempo. The lone voice eighth notes as well as the sixteenth note intervals serve as comparison bases for non-echoing notes and the effect of doubled eighths.

from @DmitryArefiev : it happens with intervals on one Flute staff and doesn't occur with the same notes separated into two staves
