High Pitched Noise - DDJ-1000 | headphones and master

Hi Guys,

I've just bought the DDJ-1000 and still currently analysing around 15,000 songs but I just wanted to jump on the controller and have a play around with it.

Every couple of minuetes when I'm trying to mix I get a high pitched noise in my headphones and Master it will come on for a coupke of seconds which is really annoying

My Specs are -

32gb of RAM

i5 processer

HDD - 732gb free Total 990gb

External SSD - where my music is stored

I've got a feeling it could be becouse it's still analysing tracks (I'm not playing the tracks that havn't been analysed) and can't handle the tasks that it's doing?

Thanks in advance!
