I have been working with the PreSonus 1818VSL for about a month now. Long hard learning curve. And add to that I made the move from windows XP to Win 7 and new computer, so I have had issues. But I am getting there.
The one problem I have not been able to solve is the random clicks and pops on the tracks I have recorded. I am using Mixcraft 5 current rev. and never had this problem before on my old system. The noise is not in the track though, just thru the play back. Never in the same place and I here them when I record or play back the track. These tracks are acoustic guitar plugged in and over mics as well. The CPU meter never gets above 17 -18%, usually around 6% usage. I’m not on line, the virus software is turned off when I record, I went through the optimization guide, not sure what else to do
