Ok this is really strange. Im not even sure too much on how to describe the sound

Its not from the music because it happens while nothing is playing

I was just going over the controlls, getting familiar with them
nothing was playing
at one point, nothing was in either deck and still the sound happened

i tried over and over again to reproduce it intentially but i cant.

Its a random sound.

Almost sounds like its computer generated.
Like a glitch sound or a squeetch.

really high pitched, and really short. Less then a second
I mean you are talking like less then 1/4 of a second but its loud and just barely long enough to notice it in the audio.

While listening with headphones, i use the MAIN OUTS on the Kontrol S4 and plugged them into my external dj mixer input (channel 3)
so i had my headphones pluged into my dj mixer, no KS4

i did this to make sure the sound was coming from the S4 and no where else.

it is.

I even saw the audio signal peak on my mixer input level.

Not sure whats happening here.
Like i said
its random
happens when music is playing or not.

any advice on what to look for?
