What is a VST2?

VST2 is a version of the Virtual Studio Technology plugin format developed by Steinberg that allows digital audio workstations (DAWs) to load virtual instruments and audio effects. It became one of the most widely used plugin standards in music production during the early 2000s.

VST2 plugins can function either as virtual instruments that generate sound or as audio effects that process existing audio. Examples include synthesizers, samplers, equalizers, compressors, reverbs, and delays. These plugins run inside compatible DAWs and allow producers to expand the capabilities of their music production software.

Although VST2 was extremely popular for many years, Steinberg eventually replaced it with the newer VST3 format, which offers improved efficiency, better automation handling, and more advanced audio routing features. Despite this transition, many older VST2 plugins are still widely used in music production environments today.
