I recorded 3 different parts of the song 16 Days by West.K. It’s a track I bought from beatport.com and is a 320kbps mp3. The recording is about 60 seconds.
First part is at 0%, second is -2%, and third is -2% with key lock. You can hear a huge difference on the third part.

If you try it out and let me know how it sounds on your 2900 that would be a tremendous help. No need to record it unless you want to. I think the 1200s just don’t have a strong enough sound card to process the information.
Thanks so much!
