Best Synth Plugins for Windows (2026)
The best synth plugins for Windows are Vital, Surge XT and Spitfire LABS. Vital is best for producers who want Serum-style sound design for free (Free (paid tiers add presets and wavetables)). Surge XT is best for budget-conscious producers wanting a fully free, open-source synth with pro-level features (Free). Spitfire LABS is best for producers wanting free, high-quality Spitfire-recorded instruments (legacy plugin, being discontinued Oct 31 2026) (Free).
