My DSP meter has one single blue bar, yet when I play a beat (4-on-the-floor), 25% of the time during the loop around, or when changing volume, there is a loud pop/crackle sound. Why is this?
What Mac OS are you using? Also what version of Reason 6.5? Make sure that you download the 'very' latest version of Reason (ver. 6.5.3) as it 'addresses' this issue (which is what I think is the problem here) of scrolling = crackling in Mac OS 10.8
If this doesn't work then it's time you called the 'Support' crew in to your rescue
Hope this helps!
