Lets start an argument, whats your thoughts on them? Vote and discuss Read Below if you dont know what they are: What they simply are is a new feature on Pioneers high end CDJ models the CDJ2000 and the CDJ900, now on a normal CDJ you have to enter the start of the loop With the left button, button A, and then set the end of the loop with the right button, button B But with the Quantized loops, if you go to set the start of the loop on beat 1 or a kick drum and you miss it by half a second Quantized looping will automatically set the start of the loop on that beat, so it auto fixes your mistake and gives you perfect loops everytime....
