Bumping this old topic! I have the exact same problem as the original poster, and I’ve tried copying and pasting the code provided by jezalenko but Virtual Dj says “Syntax Error: var “filter-effect” ? param_multiply 0.7% & filter : param_multiply 1% & effect slider 1” When i try to paste it in for FX_PARAM_1 What would be causing this issue? Any help would be greatly appreciated!
