Hi, this might be a known problem but i have just noticed it. If when using The iDJ Pro filter knob you set it to a position, lets say 3 o’clock, then leave it at that position, if you then use the on-screen FX pad and swipe the filter, once let go it ignores the previous knob and reverts to un-filtered sound, which means you need to turn the Knob quickly back to the 0 position but as soon as you touch the knob the sounds cuts to that filter position (worse if knob is turned to full).
Hope this makes sence.
Ideally the knob position should be memorized for one the pad has bern released.
