Drag-and-drop modulation slots

One of the best features of FabFilter Twin 2 is undoubtedly the ability to set up modulation connections with drag-and-drop. There is no need to search through long drop-down menus containing dozens of sources and targets or to find your way in cluttered and obscure matrix views. This simple method of making modulation connections makes sound designing become fun, easy and, above all: fast. So how does it work?

Grab a source...

... drag it to a target...

... and drop it.

First, grab the source drag button that you would like to use as a modulation signal, for example XLFO 1. The moment you click on the source drag button, the interface dims and all modulation targets are highlighted.

The moment you start dragging, you will see a line from the source drag button to the icon that you are dragging. If you hover the mouse over any of the component buttons it will automatically open. It will then snap to any available modulation target.

Now drop the icon on the highlighted knob of the parameter that you would like to modulate, for example the Master Tune knob. That's all there is to it!

If you wish, you can also add a slot manually using the small plus button above each modulation source. You can also modulate slot level knobs, which makes incredibly complex modulation setups possible. To sort the slots click the + button in the source selection bar and select Sort Slots from the menu that pops up.

Once a slot has been added, you can edit it:

  • Use the Level slider to adjust the amount of modulation. Like with knobs, hold down Shift for fine-tuning; hold down Alt to adjust all slot levels for the same source; Ctrl-click (Windows) or Command-click (macOS) to reset the level to the default value.
  • To the left of the Level slider, you can invert the modulation signal with the +/- button.
  • When you hover over the slider on the left an on/off button appears. Use this to temporarily disable the slot. On the right a menu is accessible that gives direct access to all available modulation targets.
  • To delete the slot, click the Remove button to the right of the Level slider.

Our what-you-use-is-what-you-see interface makes complex programming very easy. Twin 2 uses dynamic slot highlighting to visualize all the sources that modulate a specific target. When a parameter is modulated a small modulation indicator appears:

Click the modulator indicator to highlight all slots that modulate this target. In the source selection bar the sources that modulate the target are also highlighted.

This feature makes programming so much more fun because it's easy to see what is happening inside a patch. To return to the normal interface click anywhere on the interface background or click the Modulation Indicator again.

When a modulation indicator appears next to a component button or envelope generator it means one or more parameters are modulated. When you click that indicator it will highlight all slots that modulate a target of the component or envelope generator.
