Have you tried increasing the latency to see if it goes away? We can’t tell what your exact problem is – just try it and see 🙂
With latency, the lower it is the greater the processing power it requires to keep up – so if you are doing lots of effects/different channels/loading decks all at the same time this will also put extra strain on your CPU. This can cause your CPU to max out, which then causes glitches in the audio. Most DJ software is good at prioritizing the audio engine to prevent this, but that may not be enough if the peaks are big.
Do the glitches happen when you do anything in particular??
Also, your CPU is relatively low powered in comparison to the i5’s used in most hmid-high end PCs at the minute – so try reducing your CPU load. if that fixes it, you have found the problem..
