Modulation

Modular sound design employs modules as the basis of design. The modules in FabFilter Twin 2 are the three oscillators, the multimode filters, the delays, the XY Controller, the XLFO, the Envelope Generator, the Envelope Follower and the MIDI source. Each of these modules have parameters that can be changed by both knob movements and modulation. These parameters are called modulation targets. The modules that can send control signals to the modulation targets are called modulation sources. The modulation signal always flows via a modulation slot that allows you to vary the extent of modulation.

FabFilter Twin 2 offers very flexible modulation possibilities which make this plug-in capable of many sound design applications. Ever-changing parameters can make your music become more alive because an exact reoccurrence is very unlikely to happen.

FabFilter Twin 2 - Modulation section

Use the Modulation button at the top to show or hide the entire modulation section, which consists of the following elements:

  • Source selection bar
    The source selection bar shows a schematic overview of all modulation sources at all times. Simply click on a source button here to scroll the source into view. The highlighted section of the bar shows the currently visible part, and it can be dragged to scroll the sources as well. The top segment of each source button lights up according to the modulation signal it is currently sending.
  • Modulation slots
    As said before: every modulation source uses a modulation slot to send its signal to the target. Twin 2 always groups all modulation slots above the source that they're connected to. Each slot displays the destination, graphically shows the amount, and you can quickly turn it on or off, or reverse its output.
  • Modulation sources
    The modulation sources are organized in a horizontally scrolling strip below the source selection bar. There are 5 different kinds of sources available: The XLFO can generate almost any waveform you can imagine and can be synchronized to the host tempo. The Envelope Generator is of the usual ADSR kind and triggered by audio or MIDI. The Envelope Follower will follow the loudness of the incoming audio or side-chain signal. The MIDI source transforms any incoming MIDI data into a modulation signal. And the XY Controller lets you modulate two targets using horizontal and vertical mouse movements.

    To add a modulation source, click the + button in the source selection bar.

    To delete a modulation source, click the remove button in the top right corner in the source interface. When a source is deleted, modulation slots that use that source will also be deleted automatically.

Tip: You can scroll the modulation source section with the mouse wheel. On Windows, most mouse wheels only work vertically, but you can hold down the Ctrl and Shift keys for horizontal scrolling in that case.
