Adding Videos or Visuals to an mp3

[poginho]

I tried, but I can only change the output to 1 or 2, not to 3 or 4.

Outputs work as a pair (left & right) so :
[01] 1&2
[02] 3&4

So if you want to outputs 4 decks you need to mix internally not externally or have a soundcard that can handle 4 outputs (8 connectors).

Ok, thanks. I will try that.
