Hi ReTry,

To elaborate on jford's post. VST stands for Virtual Studio Technology, with the "i" being for instrument.

VST is a software interface that integrates software audio synthesizer and effect plugins with audio editors and recording systems. Often used to simulate traditional studio hardware in software. Thousands of plugins exist, both commercial and freeware, and a large number of audio applications support VST under license from its creator, Steinberg.
