Tracks aren't turning green when played / marked in history


The Sixty-Eight uses the same A-B system as all other hardware - this means that tracks are only marked played (green) and added to history once a track on the other deck has been loaded.
It appears that this is only working when the selected primary decks are 1&2. We'll make sure this is fixed in an update. As a work around for the moment, if using only two decks, make sure 1&2 are set as your "primary decks".
That should ensure that tracks turn green and are listed in history.

If you are using more than two decks, or you don't want to change things around too much, the tracks will still be listed in history - you will just need to check the "show un-played tracks" box.

The selected decks layers are also related to the holding ctrl - up problem you mentioned:

Control left and right loads to the currently selected left and right decks (the ones with the flashing red border around them. Control up and down loads to the current unselected left and right decks.
To change the selected decks, use the tilde key: ~ or the layer button on the Sixty-Eight.

Hope that helps a little :)
