Murf output problem

Hi, is it normal that a few sounds are going thru the output on the first pattern with all the sliders down ?
is it normal that a few sound is bleeding thru the output on small enveloppe settings?
i can still hear the original sound (wery tiny but audible) even with the mix button at full setting ?

is it a vca callibration problem ?


all the murf does that ?

thanks
best

the Murf is gone to service
it was a faulty unit…
