Valhalla‘s free Supermassive has gotten even larger with its latest 1.2 update. The free creative reverb plug-in adds two new modes that call back to modulated 80s digital verbs.

Continuing its cosmic naming theme, the news modes, Cirrus Major and Cirrus Minor are said to offer “bumpy” and “rough” reverberations – plus loads to explore when it comes to dialling in that feedback knob.

“[The new modes] create echo patterns that repeat in weird ways,” wrote Valhalla in a statement. “The density is far less than other modes, and even at their densest you can hear strange repeating patterns.”

Cirrus Major is the denser of the two and has a shorter pre-delay. According to Valhalla, it’s possible to summon intense modulated patterns by dialling up on the warp and density controls.

“If you turn Warp up to 60% or more and turn Density up to 100%, you can use the Cirrus Major and Cirrus Minor modes as an 80s modulated reverb,” it explained. “There will be a fair amount of pre-delay baked into the sound, but this is useful for emulating the sound of something like the H3000 Swept Reverb.”

Both modes were also named after developer Sean Costello’s favourite Pink Floyd song, Cirrus Minor.
