Valhalla Supermassive is a reverb and delay plug-in that Valhalla DSP gives away for free. As the name suggests, it specialises in making “massive” reverbs and echoes. It is a candidate when you want the vastness of space, or a slowly building reverb, rather than the sound of an ordinary room. This page covers how to get it, its features and where it fits.

How to get Valhalla Supermassive
- Open the Valhalla Supermassive official page (free).
- From “GO TO DOWNLOADS” at the top of the page, go to the download area.
- Download the installer that matches your operating system (Windows or Mac) and run it.
- Open your DAW (recording and production software) and rescan for plug-ins.
- Load Supermassive as an insert or on a send (a track you send audio to) on a track.
The official page says: “And it’s free. No strings attached.”
What is Valhalla Supermassive?
The official site describes Supermassive as a plug-in designed from the ground up for “MASSIVE” delays and reverbs. It is said to be good at billowing clouds of reverb, otherworldly delays, and sounds where feedback (routing the output back to the input) swells like waves.
Inside, it is a feedback delay network (a method of making reverb by combining several delays), and the official site says each delay in the structure can be up to 2 seconds long. Combined with its own “WARP” control, it can reportedly make slowly fading-in echoes, layered echoes with a sense of pitch, and reverbs that die away over several minutes.
Valhalla DSP also has paid reverbs and delays (VintageVerb, FutureVerb, Room, Plate, Shimmer and more), and Supermassive is the free product among them.
Main features
- 22 modes (per the manufacturer): There are modes named after stars and constellations: Gemini, Hydra, Centaurus, Sagittarius, Great Annihilator, Andromeda, Lyra, Capricorn, Large Magellanic Cloud, Triangulum, Cirrus Major, Cirrus Minor, Cassiopeia, Orion, Aquarius, Pisces, Scorpio, Libra, Leo, Virgo, Pleiades and Sirius.
- Each mode has its own character (per the manufacturer): The official site explains that the speed of attack, the length of decay and the density of echoes differ greatly from mode to mode. For example, Gemini is the most general mode, with a fast attack and a natural decay. Andromeda has the slowest attack and rings for a very long time.
- Some modes lean towards echo (per the manufacturer): Aquarius and Pisces are described as types that keep distinct echoes while turning into a rich reverb when you raise DENSITY. They may be usable somewhere between a reverb and a delay.
- Modes with filters inside the feedback (per the manufacturer): Scorpio, Libra, Leo, Virgo, Pleiades and Sirius are described as having filters inside the feedback for a more natural reverb decay.
- Version 5.0.0 update (per the manufacturer): The page says a new mode, “Sirius”, and previous/next buttons for mode selection have been added, and that versions for Mac (native for Intel and Apple Silicon) and Windows are available.
- Explanations of controls are available (per the manufacturer): Valhalla plug-ins are “self-documenting”, and hovering the mouse over a knob shows a hint explaining it.
Who it is for
- People looking for spacious, ambient effects for free
- People who want long, trailing reverbs for ambient music, cinematic songs or sound effects
- People who want to try sounds in between reverb and delay, where echoes melt away
- People who want to add a deliberately huge space behind vocals or instruments
If you only want to add a natural room sound to a vocal, some modes may feel over the top. In that case, it may suit you to start with modes that the page describes as having a fast attack and short decay, such as Gemini or Pleiades.
Tips for using it
- First, switch through the MODE settings one by one and compare the differences in how the sound starts and decays. The official site also says MODE is the control that changes the sound the most.
- The official site explains that raising DENSITY (the density of echoes) gives a smoother reverb, and lowering it gives echoes where individual grains are audible. The effect changes by mode, so compare by ear even at the same value.
- It is common to put a long reverb on a send and add a small amount to the mix. If you apply it too deeply, other sounds get buried.
- If the low end after the reverb gets muddy, one method is to put an EQ before or after the reverb and cut the low frequencies.
- When you want it to follow the tempo, it is common to adjust DELAY (the delay time) to match the tempo of the song.
Things to know before you download
- Supported operating systems: The official page lists version 5.0.0 for Mac (native for Intel and M1 to M5) and Windows.
- Supported formats: For plug-in formats (VST3, AU and so on), check the official guidance when you download. It is safest to confirm beforehand that your DAW supports them.
- Paid versions: Valhalla DSP also has paid plug-ins, but Supermassive itself is described as free.
- Always get the files from the official website.
FAQ
Q. Can I use it in commercial songs even though it is free?
The terms of use could not be confirmed on the official product page. If you are concerned about commercial use, check the terms shown at download or contact the maker.
Q. Can I use it as an ordinary reverb?
The official site describes Gemini, Pleiades and others as “more general” and suited to “realistic, transparent reverb”. Still, Supermassive as a whole is a product where huge reverbs and echoes take the lead.
Q. How is it different from the paid Valhalla plug-ins?
The official site describes Supermassive as being for “massive delays and reverbs”. Each product has its own area of strength, for example VintageVerb for old digital hardware reverbs and Plate for plate reverbs.
Valhalla Supermassive is available from the Valhalla DSP official website (free).
