my cdj 100s are doing very, very old they had to be replaced, use only animation.
So no pio pio or denon ...... useless, I needed a simple, practical and reliable, if possible.
my choice is focused on CDX4 (I had already CDX6 4) included two rules in my animation (each have 2 CDX6 which controls a PC and thus 2 CDX4 for CD, it has been turned all is well I said ......... bravo.
Price / quality ratio impeccable, okay look is a little "old school" but other than that .... no problemo.
I precise although the use is for entertainment, for sharp mix it need something else. (Personal is 2 and 2 CDJ 900CDJ 1000 MK3)
