hi, I love your Preview Player. I like to pre listen to tracks already while browsing files. this Is what I really love in Traktor. but specially for external Mixer, there should be an option, that the Preview Player is choosing automatically the right channel (fe. the channel which is not playing) . the Z2 Mixer had a good implementation, because it has internal mixing routing. but now switching over to a 2 Channel Rane Battler Mixer, there is no Channel available for the preview Player.... thanks
