I don't know if this could be CPU related - but here it is:
1: I have assembled a song consisting of only 4 tracks
2: 3 of these tracks are using Instruments from the EW sound libraries. The last track is a Choir instrument (native Musicmaker)
3: When I edit the tracks- and listen to the complete song - all sounds very well.
4: Then I mix it dows to f.e. MP3 (could also be WAV)
The resulting outputfile only consists of what I would call White noise - no music at all.
Further info: I use my onboard soundcard as play device, and are recording through the Magix Low latency driver.
What the f''' is going on? Any ideas would be welcomed.
