MS Basic Trombone Playback has annoying buzz in high register
S3 - Major
All notes from C4 and above, except for C#4 D4 and D#4, have this buzz at the sustain of the note. In some cases more then the other. I have included a chromatic trombone which will show you what it sounds like. Also, i find that dynamics and articulations have no effect on the buzz.
In this comment I've attached a .7z file with a .mp3 file of the sound, which has the buzzing.
I can reproduce this issue.
