It would be helpful for users coming from Traktor to be able to import the cue points and beat grids they set in Traktor into Mixxx. First, this depends on Mixxx supporting the types of cues that Traktor has such as loop cues and mix in/out cues.

I think the difficulty here is how to get the cues info from Traktor. Their library format is closed, it can be reverse-engineered but we don't know when they'll change it and break this feature.

Well, I've just opened the Traktor collection file and cues are stored like this:

<CUE_V2 NAME="n.n." DISPL_ORDER="0" TYPE="3" START="52.7665" LEN="0" REPEATS="-1" HOTCUE="0"></CUE_V2>

So as long as they stay with xml it shouldn't be that hard to do.

We should investigate why the tag is called CUE_V2. Are there collections with CUE or CUE_V1 tags out there?

I guess you are meaning tracks in the Mixxx's Traktor library node, isn't it?

hile said on IRC that the CUE_V2 format has been use since Traktor 3, which was released in 2006 (http://www.synthtopia.com/content/2006/10/11/native-instruments-ending-finalscratch-dj-relationship/ ) and confusingly predates Traktor Pro 2. So there is no good reason to spend the effort on supporting the old format.

I started a wiki page for documenting Traktor's cue storage format: http://mixxx.org/wiki/doku.php/traktor_cue_storage_format?do=edit

Hi,
I've now took the time to document all the options I'm aware to do this conversion, including the "cues shifted in time" issue
