In 3.0.6-116 we have adjusted the mp3 parameters to create a good mp3 export quality.
We have received a report from one of our beta participants that the current parameters work fine for the default soundfonts but some other soundfont like the
Timbres of Heaven soundfont result in heavy clippings in the exported audio files. The reason is the different volume of the soundfonts. We work with this beta tester off-line on a concept to be able to have according parameters configurable. We will post more info here in this thread.
