Valhalla Supermassive gets new Sirius reverb/delay mode in v5.0 update

ValhallaDSP has announced the release of an updated version of its free reverb effect plugin designed for massive delays and reverbs.

Valhalla Supermassive 5.0.0 brings a new Sirius mode with fast attack, smooth decay, low to very high echo density, and filtered feedback.

The Sirius mode excels at short to long reverbs that remain clear throughout their whole decay. The Low Cut and High Cut filters in Sirius are more powerful than in most Supermassive modes, and are useful in obtaining realistic high frequency decays, as well as reverbs where the low frequencies thin out with the decay. The echos from Sirius are more standard echoes than some of the other modes, which makes Sirius useful for modulated delays.

We’ve found Sirius to be more of a “workhorse” mode versus super strange, but the long reverbs can get into some super spacey territory. The LATE 2025 presets folder showcases some of the best Sirius applications, and is a great place to start learning how to use this new mode.

The update also comes with previous/next arrows to quickly scroll through the different modes.

Valhalla Supermassive is free to download in VST/VST3, AU and AAX plugin formats for Windows and Mac.
