Technically, no, it’s a Kontakt instrument.
However, it functions just like a VST instrument in your DAW.
While musicians and producers often use "VST" as a catch-all term for any virtual instrument, Brickwall Drums is formatted specifically as a Kontakt library (.nki). To use it, you simply load Brickwall Drums inside Kontakt or the free Kontakt Player. Since Kontakt itself runs as a VST3, AU, or AAX plugin inside your DAW, the end result is identical: you open it, play it, and automate it just like any traditional VST.
