I have one Pioneer CDJ - 1000MK3 deck and a DJM-300S mixer.
There arent any effects on the mixer, and I cant really afford any other pieces of equipment. Could i run my laptop output into channel 2 of the mixer and the deck into channel 1 and try to mix it that way, and run the effects off the laptop? Or is there a better way?
You can run the laptop output to the mixer and if you’re using DJ software with FX use them on that channel as long as you’re playing the song in the software and not through iTunes or something like that. As far as that goes you can get pretty crazy with just a plain keyboard mapping and nothing else. I present exhibit one: Earl and his Pandaboard.
