Thanks for your fast responses!

Got up this morning and created a fast song in BB, all real tracks. I checked whether the asio was set as driver. It was on MME, so I changed it. I have an M-Audio Audiophile 192 card that runs Asio.

I rendered the song and drag and dropped the tracks into Reaper. No speed up, as attested to by my ears and also the metronome.


I believe last night I saved the files on my new drive, a WD 1 TB Caviar Black. I will experiment today and see if I can reproduce the speed up and whether the new drive had anything to do with it.
