In Traktor, beatsync aligns two tracks to the nearest beat. I've always wished there was a way to also align to the nearest BAR. ATM, when you exit a sub-beat loop e.g. 1/4 loop, there's a 50% chance that the track will be off by one beat relative to the master track and you end up with a clap or a snare on every beat which sounds bad. Apparently, Traktor DJ 2 already has barsync, as does Rekordbox. IIRC, Rekordbox goes one step further and lets you adjust the scope of the sync (4 beats, 2 beats, 1 beat). It amazes me that the toy version of Traktor gets this feature while the pro, flagship, version doesn't. This is the kind of thing people like Richie Hawtin would appreciate. So there goes my feature request, thanks!
