Soundtoys has just dropped a new plugin called SpaceBlender, and if you’re into spacious, modulated reverbs with movement and grit, this one’s worth a closer look.

Think of SpaceBlender as a mashup between a reverb and a modulation unit—but on steroids. It’s got a dual-engine architecture with two independent reverb processors, A and B. You can load up different algorithms on each—like plates, springs, chambers, granular washes—and then morph between them with a dedicated Blender control. That alone makes it stand out from most bread-and-butter reverb plugins.
The modulation side is where things get wild. SpaceBlender lets you modulate nearly every key parameter using its built-in LFOs and envelope followers. Want a reverb that pulsates with your track’s dynamics or shifts textures in sync with the beat? No problem.
It also features:
- Per-engine controls: Tailor each reverb with filters, decay, size, and character settings.
- Dynamic response: Reacts to audio input, great for rhythmic and expressive FX.
- Creative presets: From lo-fi dub echoes to lush ambient swells.
GUI-wise, it’s what you’d expect from Soundtoys: clean, tweakable, and fun. The plugin is available in VST, AU, and AAX formats, and if you own the Soundtoys 5 bundle, you can grab it as a paid upgrade.

Is it just another reverb? Nope. It’s more like a reverb that went through a blender, an LFO, and a bit of cosmic interference. If you like the unpredictability and texture-twisting sound design tools, SpaceBlender might be your new secret weapon.
If you’re into SpaceBlender, here’s a list of similar creative reverb/modulation hybrids and experimental spatial FX that bring movement, morphing, or modulation to the reverb game:
Modulated & Dual-Reverb Style Plugins
- Eventide Blackhole
- Cosmic, infinite-style reverb with pitch shifting and modulation.
