Native Instruments 23516 DJ Controller

I have two of these along with a S5 for a four deck setup. Absolutely solid, not had any issues with them unlike the previous s4 model that was prone to crashes and calibration issues. The setup was a bit of a pain as my computer didn't always recognise the drivers which meant installing it and uninstalling the software about 3 times. While I do have an i7 processor you need a decentish gpu "my laptop is from 2012" the reason for this is to run the graphics built into the hardware. For some computers it might run these a bit Jerky if it can handle it. Sometimes this issue can be fixes by updating the gpu to the latest and drivers and software which worked for me.
