small bugs in the new Brass update

first of all beautifull update that you guys have done my compliments for it.

i found a few bugs in the brass update.
1.) the brass doesnt stay on the same volume and gets softer around 4 measures.
2.) ghost notes. i hear notes that aren't writen in by me.
3.)Dynamics. there is still to much difference in mp/mf/f

in the file that i sended with this report you can hear them all in it

measure 16: F horn goes louder/sharper without any input by the user
measure 45/50 bass solo is no decrecendo but its from forte to almost piano in 2 measures time

hopefully you can work with it and keep improving the program.
and again you guys did a wonderfull job with the update for the sound as in the UI
