The control code is designed to nudge the pitch up or down if the timecode of the track is drifting compared to the timecode coming in from control code. This makes sense in vinyl-land, where there are variations in pressings, but shouldn't happen with CDs. If the playback is out of sync with the CDs, it implies that xwax is interpreting the pitch wrong. If you've got pitch set at 0, does mixxx show the playback speed at +/- 0 bpm? First, I would make sure that needleskip prevention is turned off, because that's definitely not needed with CDs. Not sure if that will help though. > > Also even at latency set to 23 ms after first loading mixxx and loading > a track in a deck and starting it, it would play at 1/4 speed and then > catch up after a few seconds.

When you say it sounds 1/4 speed, does the pitch drop too or is it just stuttering? Does the bpm indicator also drop, or is the problem just in playback? Do you get playback problems without using CDJ control? > > btw, xwax 1.8 and 1.9 on the same hardware has almost no lag and > absolute mode works perfectly. Unfortunately I don't have an SL-1 or CDJs, so I can't really test your setup at all (unless you're based at Redhat's Boston office). I'll try to help debug this problem, though.

Yes, in fact the BPM normally doesn't change, even when the pitch does change as I move the pitch on the CDJ up and down. When I say it's wonky I mean the pitch fader in the GUI goes up and down. I don't remember if the BPM went up and down with it, I'll check though. > First, I would make sure that needleskip prevention is turned off, > because that's definitely not needed with CDs.

Do you get > playback problems without using CDJ control? I don't get stuttering when not using vinyl control. This is from memory when I tested it a week or two ago on 1.9.0. I need to check agan. >> btw, xwax 1.8 and 1.9 on the same hardware has almost no lag and >> absolute mode works perfectly. > > Unfortunately I don't have an SL-1 or CDJs, so I can't really test your > setup at all (unless you're based at Redhat's Boston office).
