Topic: Mapping the Noise FX for a "Sweep" effect
rayanPRO InfinityMember since 2024
Hey fellow DJs,

I'm kinda new to the game, but I learned the basics with Virtual DJ, so I now got the pro license and want to use every bit of customization this awesome program has to offer.

Especially for a beginner like me the sweep (noise FX on 12 o'clock, turning it down to anti-clockwise and turning off the FX) is cheap, but great to hype up a drop or spice up a transition. But it keeps at least one hand busy while it's needed elsewhere.

I use a hardware FX knob on my controller for the Noise FX. It acts two ways with a neutral position at 12 o'clock (which is hard to find without a locking mechanism): Turning it anti-clockwise the noise grows deeper in pitch, clockwise higher (which I don't use because the sound is annoying). That's why I want to ask:

1) Would it be possible to change the effect so that the neutral position is at the maximum of the fader knob? That would of course imply I only use it for a low noise effect.

2) Would it be possible to change the effect so that the effect turns off once the fader knob reaches the minimum position? This would be an awesome feature.

3) Another solution, if the ones above are not working: Mapping the Noise FX to the Low Pass / High Pass Filter Knob would at least help with a fixed 12 o'clock position. How to do that?

Those options would allow to apply the "sweep low" effect more intuitively and also obtain creative freedom on the length and intensity of the effect. It would still be great to apply the FX matched to the beat - I know there are some samples around there, but how to adjust their length to the current BPM?

And in general, how are others doing the sweep effect? Any further tips?

Thanks a lot!

Yes 1 & 2 can be done, hardware manipulation to software effect is where vdj stands out.

You just need ( maybe a condition and ), to manipulate the value sent from the hardware.
So the hardware dial sends a signal of 0.0 - 1.0.

So what you want in this case is just multiply that value by 0.5 and then pass that value to the dial

param_multiply 0.5 & filter


this will control whatever is on the color fx slot at 2 times resolution [ hw 0.0 to 1.0 becomes 0.0 to 0.5 in the software]
if you want it conditional [so that it only scales the dial when noise fx is on slot, just query what is in the color fx slot
filter_selectcolorfx noise ? param_multiply 0.5 & filter : filter


is noise in position ? yes, do the maths : no, just control whatever is on the colorfx slot [aka the filter slot] with scaling [1:1]

*edit, I missed the reply to 2

filter 0.0 ? filter_activate off : filter_activate on & param_multiply 0.5 & filter

I want to follow this threat because I'm very interested in this as well.

I am wondering - as this is a hardware FX - do you "bypass" the hardware FX then and just use the software filters? It would be great to use color filters too...

Awesome, thanks for providing the code! I tried to wrap my head around the parameters and remapped the according hardware knob. Unfortunately... it does not seem to work: The noise filter level now just doesn't react at all.

What's that? That isn't what I posted.

These are the codes you wrote down... I guess I just messed up applying and combining them. Further help would be well appreciated! After another try the FX knob now functions as a low pass filter - I'm lost.
