i dont thnik this is very good. have you ever been to a party where djs have to switch their boxes all the time? this is the biggest problem meanwhile anyway that makes pro djs playing abroad go back to cds. now, if you own the vestax 300 and another dj uses dj intro and also wants to use the vestax 300, then boxes need to be switched? and also - why isnt there an interface independent dj intro software? if i can buy that numark mixpro thing for 186 euros, serato wont earn much if anything from it. still i dont want to buy it. in fact i have my own party going next week in private and we dont have a big desk, my friend will have itch + vestax 300, i have serato scratch. why can we just plug out our laptops and both use the same interface without a lot of programming?
