Hi,
I'm dj and music producer since many years,
I use vinyls, cdjs, traktor+ controllers X1 and F1
I recently bought 2 cdj 2000 nexus units + dim 900nxs.
I know how to mix by ear it's not an issue for me at all.
I know how to set perfect girds too ... love to use both worlds depending on my mood :P
Found it weird that sync dont work well with a perfectly manually adjusted beatgird on the highest zoom level, it should be some issues with the 2 units sending bad midi clock, at some moment it is drifting for a second or tow then come synced...
I assume the system is using midi time code not midi clock since it's showing phase... mtc should be rocking solid on a 100 mbps lan ..
Im really optimistic since I know this will be corrected with a recent firmware...
For the moment I m using beatmatch by ear with those units...
