In this video tutorial, Vincent — co-founder of Pulsar Audio — walks Conor through Primavera, Pulsar’s take on timeless spring reverb, rebuilt for modern production.

Primavera – Organic Spring Reverb

Vintage character, physically modeled and creatively extended

Six legendary spring tanks. One plugin. Infinite motion.

Spring reverbs are loved for their warm, organic, and unmistakably characterful sound — but the originals are rare, fragile, and expensive. Primavera faithfully recreates the electronic and mechanical behavior of classic spring units using real-time physical modeling, not static convolution.

That means you’re not just choosing a sound — you’re shaping the springs themselves.

From clean, dense British tanks to gritty lo-fi amp reverbs and dub-style tube units, Primavera covers everything from hi-fi depth to explosive “boing” chaos, all with hands-on control over tension, excitation, and movement.

Model the physics, not just the impulse:

Real-time spring modeling (not sampled IRs)

Adjustable spring tension for tonal and rhythmic control

Excitation and “kick the springs” interaction for sound design

Six iconic spring tanks, from pristine to unapologetically dirty

A Complete Spring Reverb Chain

Primavera isn’t just a reverb — it’s a full processing chain designed to sit perfectly in a mix. Shape tone before and after the springs with tube or germanium saturation, filtering, presence control, stereo width, and intelligent ducking.

Dense, characterful reverbs stay out of the way when the source plays, then bloom naturally in the gaps — even reacting to external sidechain signals when needed.

From subtle depth on vocals to spring-smeared snares, surf guitars, dub sends, and animated synth textures, Primavera brings the unmistakable personality of vintage hardware into a flexible, modern workflow.

You don’t just add reverb.
You excite, stretch, and play the springs themselves.
