Reply to Connecting studio monitors via MIDI mixer

Hi,

I recently purchased a pair of PreSonus Eris 8's and I was wondering if I could connect these to my 13" macbook through my PIONEER DDJ ERGO and no other soundcard? On the PIONEER site it does say that this also functions as an 'audio interface', but I don't really know what that means.

I would like to use these to produce through Logic without having to purchase another soundcard. They do work perfectly when connected to the mixer and then used on Virtual DJ LE, but not through iTunes or anything else.

Thanks for the support,

Ale
