: It lacks the sample-accurate automation found in newer formats, which can lead to minor timing discrepancies during complex mix movements.

Before the advent of VST2, the concept of the "virtual studio" was incomplete. The original VST standard, introduced in 1996, was groundbreaking in that it allowed third-party developers to create audio effects—such as reverb, EQ, and compression—that could run inside a DAW. However, the original standard had a significant limitation: it was designed primarily for processing audio, not generating it. At the turn of the millennium, hardware synthesizers, samplers, and drum machines were still the backbone of production because computers lacked a standardized way to host virtual instruments.

However, the very strengths of VST2 eventually became its limitations as technology advanced. The flexibility of the VST2 codebase meant that many developers took liberties with how they programmed their plugins, leading to compatibility issues across different operating systems. Furthermore, VST2 plugins lacked the sophisticated automation and routing capabilities required for modern workflows, such as handling multiple audio outputs or sophisticated parameter changes over time.
