How to make cool Stereo 3D effect on any sound you have in FL?


You might want to add in a Formula Controller. “It’s easier to use in FL12” But since it’s nearly the same and easier for FL11 users we have written this for all to understand.

On any synth put your stereo shaper in. Then choose the red mid handler first by right-clicking on it and Link to Controller by right-clicking.

Then you will see a more likely screen like this:

Try to assign “Internal Controller” for Formula CTRL – Out first.

Then Mapping Formula you change it to the Inverted Log Scale.

Now reply to this on the yellow handler and choose the Log scale. “The opposite”

That way you can use Formula Controller to automate the Stereo Shaper inverted and with normal direction.

You just want them to just change the pan, while it really offers more 3D sound to your synths or anything that complies and is compatible using it with. Most likely bass wouldn’t be a good choice for this, but surely can be done with. You will most likely end up with very low bass levels, sometimes you would need to crank that level as well up using this formula.

You need to change Formula Controller presets. Most likely too 3 Step LFO. And apply own presets to it. So that it is easier would be to produce an automation clip that strictly works as random or even interesting in the pan.

You might want to change the smoothing in different ways since a square with random will change from 0 to 50 in just milliseconds and that way you need to smooth it up to avoid to much change in the automation at one time.

It’s more like this; or for FL 12 with inverted log scale;

But to have the stereo effect in your own way, you need to set the right delay to the right or the left in the Stereo Shaper as well; Just set it how you would like it. Sometimes setting it to no value can also be a good choice. Choose wisely tho.

We also have a project FL11+ for this kind of setup with some setups also with Vocoder setup as in the same tutorial about vocoder but with different vocals solutions and robot vocals.

We aren’t using to much power to the vocals. But as well doing 224Hz center equalization as well as gaining the vocal with Fruity Limiter Gain, and are not getting that troublesome levels at it anyway.
