A Numark Mixtrack Pro can be had for about $150, and is a great controller. Algroriddim Djay for iOS, is also a much more affordable alternative. Not sure why anyone would pay $300 for a Monster-branded toy.
jtrusA Numark Mixtrack Pro is not a standalone system, you will additionally need a laptop or computer with your music on it. And Algoriddim is not a device, it is software. I'm not saying either the Numark or the Algoriddim app is good or bad, I'm just saying that you can not compare things that are obviously different from one another.
jtrusThat's most likely true, but those (laptops/tablets) still don't represent what the GODJ is no matter the software used!
Imagine a GODJ pluged into a battery operated speaker/speakers and headphones. You're done! You could be at the beach, block party, football game, the park or any other place where an outlet or even a table isn't available! You can mix real sets with samples, a real cross fader, start/pause que buttons, all with one cable for connection, 2 if you have a pair of speakers and your in stereo with no adapters and still have stereo/selectable split que headphones! And if you really wanted to get fancy you could use that laptop/tablet/cellphone to be an external source and run effects on that input as well! Don't forget even a micrpone input with effects! What other device is going to do that out of the box at any price?
