This is my first mix using an iPhone, CD decks and a laptop computer all linked to a Numark iCDMix 3. The lap top is running Vertual DJ out putting to two separate channels on the iCDMix 3 phono/ line inputs.
I have been a DJ for many years and have mixed digital media before using full digital decks such as the Numark Mixdeck and Dennon units.
This was a low cost test to make sure that the cheap sound card I used would enable to use virtual DJ via another mixer cheaply. You do need a full version of virtual DJ to do this.
