Synthesizer presets are pre-programmed sound settings for a synthesizer that can be quickly loaded and used to produce a specific sound or effect. These presets typically include parameters such as oscillator settings, envelope settings, filter settings, and modulation settings that determine the synthesizer's sound. By using presets, musicians and producers can quickly access a variety of sounds and effects without having to spend time programming and adjusting the synthesizer from scratch.

Virtual Studio Technology (VST) plugins are software designed to work within a digital audio workstation (DAW). EQ plugins are a type of VST plugin called VST effects plugins. VST effects plugins help you change your sounds in new and different ways.
