Both, the xone 42 and 62, are available for the same price of around $900 at the moment.
The 42 has a more modern layout. The 62 has two extra channels but seems to be dated already.
Which one would you choose for EDM? I don't mind the position of the x-fader on the 62 as I don't scratch.
The mixer will be for Traktor/ Audio 10/ 2x X1/ 2x F1
