Audio Mixdown > .wave makes strange sounds...

Ok I tried clicking the “Real-Time Export” button …
But I wonder about the 16 Bit if it is “worse” sound quality than 32 bit?

I must also point out that there are “small errors” when I export the song / songs to wave that sometimes I can not hear if it is wrong or not.

A button I clicked on “Update Display” is good when everything in the song is updated (takes a little longer to export) but I have heard the wrong attributed to the button has been checked.

And yes, I have a cheap sound card, but I did not think it would affect exports ring like this …
