The Filter is a key component of subtractive synthesis. It’s designed to remove certain frequencies from a sound, thus changing and enhancing the character. Filters typically consist of a cutoff control, which sets the removal of those frequencies, and a resonance control, which emphasizes the frequency of the cutoff point.

The most common form of filtering is called lowpass, which means that higher frequencies are removed while lower frequencies pass through without being removed. Most vintage synthesizers employed lowpass filtering, but some also included highpass filtering, which removes low frequencies and lets the high frequencies pass through.

Trilian includes an exceptionally versatile dual-filtering system, which features two stereo filters per layer that can be routed in series or parallel. There are 24 different filter types available, which include lowpass, highpass, bandpass and other specialized varieties. Because Trilian’s filters are stereo, they are ideal for dynamic filter panning effects.

The FILTERS section of the EDIT overview features a basic set of filter controls, such as Cutoff, Resonance, Keyboard tracking, and Filter envelope depth. The full set of filter controls is available on the FILTER ZOOM view.
