VST vs VST3: What's the Real Difference in 2026?
The Evolution of Plugins
When you install a new effect or instrument, you're often given the choice: VST or VST3? Understanding the **vst vs vst3** debate is crucial for managing your computer's CPU and ensuring your sessions stay stable.
The VST3 Advantages
- CPU Efficiency: VST3 plugins turn off their processing when no audio is passing through them. Old VST2 plugins "run" constantly, eating resources even when silent.
- Resizable Windows: Most VST3 plugins allow you to stretch the interface to fit 4K or 5K screens.
- Multiple MIDI Inputs: VST3 can handle much more complex MIDI routing for orchestral libraries.
- Sample-Accurate Automation: Your automation curves will be tighter and more precise in VST3.
⚠️ The Legacy Problem
While VST3 is superior, some older "boutique" plugins only exist in the VST2 format. If you move a project from a PC to a Mac, VST2 plugins often break, whereas VST3 is much more reliable across systems.
