Reply to question about DjTechTools 3.6.4 version mapping..

please, bare with me as I am a total beginner.
i have recently obtained vci-100 se (thank you falseads) with what i believe is 1.4 firmware.
i was following the youtube video of VCI-100se mapping tutorial after i successfully load it, and i found a one problem.
i believe i have a problem with thrid fx knob on the top right of the vci-100. it's the last of FX knobs with letter 'D' under it.
i can control the level of effect with the knobs, however, whenever i want the effect to kick in by pressing the button under it, it only high lights the 'headphone' on the left deck. the button lights up and sends data fine, and i'm completely lost..
any help will be greatly appreciated.
thank you.
