OK the effects on deck a (effects bank 1) work just fine. deck b however, responds normally in traktor, but no change in sound. I’m pretty sure it not some stupid user error, i have been at this for a while, but I can’t figure it out.
Just to the left of the waveform on deck B there is a block of numbers, 1, 2, 3 and 4. The 2 should be lit ( in orange ). It is possible to have re-routed this with the “Fx Route” button.
