I have recently installed traktor pro with an S4 and everything seems to be working fine except for one thing that I've noticed. When playing a track I'm noticing the waveform stuttering. It does not seem to have an effect on the audio quality but it is a little annoying. It goes back and forth between a smooth stream accross the screen and then the waveform will start stuttering. I've tried changing the audio settings and latency but nothing changes. I have all drivers and updates.(am I just being to picky?) I am running on OSX 10.8.2. I am greatful for any advice, thank you.
