Pulsar Audio Primavera

Spring reverbs are highly sought-after vintage audio equipment, but their rarity and high cost can make them inaccessible to many. Known for their unique, warm, characterful and organic tone, these reverbs have forged a sonic identity that spanned from the ‘50s to the ‘70s, and is back in vogue today.

Pulsar Primavera is a 6-in-1 reverberation plugin that includes devices heard on countless hits throughout the ages. From lo-fi to hi-fi, each tank precisely emulates the original units' electronic and mechanical behavior. Furthermore, exclusive spring tension and excitation controls offer a wider sound palette than typical convolution models.

The software is a complete reverb chain plugin with integrated saturation, filters, presence, and ducking controls. Get the signature “twang” tone that shaped music history, packed with next-gen features and a user-friendly interface.

Most digital spring reverbs sound flat and are poorly configurable because they sample real units rather than modeling them. With real-time physical modeling, Pulsar Primavera breaks free from these limits and allows manipulation of physical reverberation parameters, like spring tension or excitation, for unique and creative sound design possibilities.

Select from six distinct and characterful spring reverbs

1/ Great British Spring : Produces a very dense and open sound. This is the cleanest reverb in the plugin’s selection, and is ideal for vocals and other elements that need to shine above the mix.

2/ HR12 : A very lo-fi type of reverb built in Japan in the late '60s. Perfect for those who seek a vintage color, and the characteristic “boing” sound of the springs. Simple, dirty, and effective, this tank has very little low-end, which means that the initial attack of the springs is clearly heard, giving it that special lo-fi flavor.

3/ SR202 : Built on a legendary hi-fi consumer reverb, this tank sounds dark, with prominent beats in the reverb tail. It’s the least dense reverb of our selection, with a vibey “flutter” color, perfect for adding realism to a source.

4/ RE201 : Based on the classic Echo RE201 from Roland, this tank is maybe the most versatile compared to the other choices. With dense and diffuse reverberation tails, it can adapt to any source in any genre. It’s well suited on a lead vocal if you’re looking for some added excitement and color.

5/ Tubby : If you're looking for the color of old-school dub music, this tank gives you a very round and watery sound, with big beats. Great for adding subtle variations to your tracks by sending some sources into a bus with this reverb on it. A nostalgic effect that works really well on brass, skank keys, or guitars.

6/ Twang : For this tank, Pulsar took their inspiration from the guitar amps that popularized spring reverbs. Widely used in Fender and other classic instrument amplifiers, this reverb gives you the lo-fi sound that you’d expect from vintage gear, with tons of character and color.

Product Features

• Drive and Saturation Mode: Adjust the level of saturation applied by the input preamplifier with the Drive knob. Uniquely, this saturation is also applied to the Dry sound.
• Tension: The Tension parameter alters the tension of the simulated springs to change the reverb’s character.
• Excitation: The Excitation knob allows you to simulate springs shaking, similar to when clicked on with the mouse, but this time automatically.
• Ducking: For those who are familiar with the kick/bass sidechain technique that is carried out with a compressor, the Ducking knob applies the same concept. It controls a compressor that reduces the reverb level when the instrument or voice passes through the reverb to clarify your mix easily.
• Vibrating Springs: This feature perfectly captures the spirit of spring reverb units, allowing you to play with the device and find inspiration in a fun and rewarding way.
• Predelay and Decay: You can control the length of the reverb tail, short or long, by using the Decay knob. Or adjust the delay between the original signal and the start of the reverberated sound with Predelay.
• Width: Pulsar Primavera comes with a Width knob to let you control the stereo image of the reverb.
• Presence: This knob creates a slight emphasis on the upper mids of your reverberated signal, enhancing the reverb's presence in the mix.
• External Sidechain: The Ducking can optionally be set to use an external sidechain signal.
• Filters: A choice of built-in 12dB/octave High-pass and Low-pass filters are also available to clean up your source before sending it into the reverb. These filters are processed just after the preamplifier emulation stage, and at their minimum value are deactivated after a notch.
