FL Studio – How to Create a Sweep Effect Generator [VIDEO]

In this video I show you how to create a sweep effect generator in FL Studio using the Patcher, SimSynth and Fruity Parametric EQ. I’d recommend watching full screen at 1080 resolution.


In this tutorial I show you how to make a quick and easy sweep effect generator which you can then develop and use for transitions and other such effects.

Creating the Sweep Effect Generator

We’re going to create this in a Patcher so start by loading one into your channel rack. We then need to add a SimSynth and Fruity Parametric EQ II to the Patcher. This can be done by dragging and dropping them from the plugin database in the browser. Be sure to route the signal through the Parametric EQ in the Patcher before it is linked to To FL Studio. 

The SimSynth needs to be set up so it’s just making white noise. Do this by turning off all oscillators except the first one, which should be set to the noise shape. Turn off all other additional processes such as the SVF and LFO. Set the amp envelope to zero attack, zero decay, full sustain and a short release (you can change these later as you desire).

Set up your Fruity Parametric EQ so that it has just one Band Pass type band on it. See my guide to the Fruity Parametric EQ for more info on how this EQ works.

Whilst you have the Parametric EQ open right click on the band pass band’s frequency dial and select Activate. Do the same for the width dial. This will add two red parameter dots to the right of the EQ in the Patcher.

Controlling the Sweep Effect Generator

Next, switch to the Surface of the Patcher and add two dials, one for frequency and one for width. Click back to the map and you wil lsee two red dots on the right side of the Surface module. Link these to the Parametric EQ by clicking and holding the mouse then dragging to the corresponding red dot on the EQ and letting go.

Next, right click on the Surface module and select Inputs then Parameters, then click the first parameter to create an input for it. Finally do the same for the second parameter. This should result in two red dots to the left of the Surface module. Your map should then look something like this:

You can now link each of the knobs on the Surface to any external controller or internal automation clip by right-clicking and selecting the relevant option. In my video I link to a couple of the knobs on my Akai MPK Mini, but you can use any controller with knobs or sliders on it.

And There You Have It

You have now built a simple sweep generator. Build on this by adding effects such as distortiondelay and reverb... anything you like, really. It’s such a fun little tool to play with! Please do let me know how you got on with this tutorial in the comments or on my Facebook page or on Twitter and I’d love to see how you develop this simple idea in your own music so please do share.
