In this case it is very easy: I am not sure yet, if there's really an issue or if its just in my head. So, I first wanted to make sure, before posting something to the list. I just answered to your mail offlist, just in time, as you're always a really fast guy and i wanted to point out, that I think i have the same, or maybe similar issue here. > Please, this is a serious issue that should be discussed on the lists. yeah... and therefore I wanted to test first ... > What are your playback settings for Qtractor?

I am sure it is "Best Quality", but i do not need to convert a smaple rate as i do not change a speed or something... > I've got this muddy sound also when I connect the output directly to the > input of Qtractor, without having JAMin launched.
