[Beta Testers Wanted] Voltaverb — Convolution Reverb with XY IR Morphing (macOS/Windows)

[VoltaPlugins]

Hi all,

I'm Ben, founder and sole developer of Volta Plugins Ltd, based in Cambridge, UK. I'm about to launch my first plugin — Voltaverb, a professional convolution reverb — in May 2026, and I'm looking for a small group of engaged beta testers to help put it through its paces before release.

What it is
Voltaverb is a convolution reverb built in JUCE/C++ with a focus on creative spatial processing rather than just realistic space emulation. Key features:

• 4-slot IR morphing with an XY pad for real-time blending between spaces

• Pan-following reverb that tracks your source's stereo position

• Low-latency engine (~11ms) with automatic DAW delay compensation, plus HQ mode with 12ms
  parameter response

• Granular processing engine with live visualiser

• Vintage character modes (tube, tape, vinyl, lo-fi)

• Tempo-synced rhythmic gate

• 6-band parametric EQ, compressor, dual LFO modulation

• Freeze, reverse, pure mode

• Factory IR library spanning real spaces, classic hardware reverbs, speakers, and unusual objects

• Loads any standard WAV or AIFF impulse response (including true stereo / 4-channel)

There's a short XY Morph Pad demo video and three dry/wet audio demos on the site: voltaplugins.com

What I'm looking for

• Active producers using a modern DAW (Logic, Ableton, Reaper, FL Studio, Cubase, Pro Tools)

• macOS 11 Big Sur or later (AU or VST3), or Windows 10+ (VST3)

• Willing to work through at least 1-2 structured test sessions (each takes 20-30 minutes)

• Honest, constructive feedback — what's broken, what's confusing, what could be better

What you get

• A free full license at launch (launch price £149, regular price £195)

• Credit in the plugin documentation as a beta tester (optional)

• Early access to a plugin built by a producer, for producers

How it works
I've built a private beta portal with 4 focused test sessions covering installation, core sound, spatial controls, and stability. Each session includes structured test cases with pass/fail/comment fields, and results are emailed straight to me. No messy spreadsheets, no vague feedback forms.
Interested?

PM me your email address and I'll send the download link, license code, and access to the beta portal. First-come, first-served — looking for around 5-8 engaged testers for solid platform and DAW coverage.

Cheers,
Ben

That sounds like two separate products to me, one spatial X-Y panning reverb and one creative multi-effect.

That sounds like two separate products to me, one spatial X-Y panning reverb and one creative multi-effect.

Fair observation, and one I've thought about a lot during development. The reason they live together rather than as two separate products comes down to how I personally use convolution reverb in production: the spatial/morph behaviour and the creative effects feed each other. Morphing between IRs while a granular layer is doing its thing produces sounds you can't really achieve by chaining two separate plugins, because the effects chain reacts to the morph state in real time rather than to a static IR.

That said, I'm not against the idea of a more focused "spatial only" version eventually — it's something I've considered for a future Volta Plugins release. For v1, I wanted Voltaverb to be one tool that covers the full creative space, rather than asking producers to buy two things to get one workflow.

Whether that decision was right is genuinely something beta testing will help me figure out. Appreciate you raising it.

Can you post a screenshot?

Can you post a screenshot?

Of course — here's the main view:

The tabs along the top (IR Browser, Reverb, EQ, Dynamics, Effects, Modulation, Spatial) give you an idea of the scope — the XY morph is the headline feature, but each tab drills into a specific area of processing that feeds off the current IR state.

Can you also post the Reverb tab?

Hey Uncle E. I managed to view every single tab on the website, though here's the Reverb panel.

Now I see why it needs its own tab!

£149 is expensive but maybe you could have that as your flagship, then separate each tab into individual plugins later. Maybe give Voltaverb owners the individual plugins for free, that way it becomes a bundle of sorts. £149 for a bundle isn't bad.

Thanks, Eric — I genuinely appreciate the suggestion, and it's something I've thought about. A few devs do exactly what you're describing (Soundtoys being the obvious one), and it can work well.
A couple of reasons I haven't gone that route for v1, though:
First, the tabs aren't really standalone processors — they share state and signal flow with the core convolution engine. The EQ, Dynamics, and Effects sections all feed off the current IR morph position in real time, so splitting them into separate plugins would lose some of what makes them distinctive in context.
Second, more honestly: I don't want to release another generic EQ or compressor as a standalone product unless I can offer something genuinely innovative. The market is already saturated with excellent options, and adding another "yet another EQ" to the pile doesn't feel right to me. Inside Voltaverb, those sections earn their place because they're shaping the convolution signal in a specific spatial context — but as standalones, they'd just be commodities.
If a signature feature like the granular engine or the pan-following behaviour eventually warrants its own focused plugin, that's a different conversation — those would be products with a real reason to exist.
On pricing — £149 is the launch offer for the first 30 days, £195 after. For a v1 from a solo dev launching into a space that includes Altiverb (£600+), LiquidSonics (£300-£500), and various £200 convolution plugins, I've landed on that figure deliberately. I take your point that the value needs to be obvious, which I'm carefully considering for the launch marketing.
Thanks again for the thoughtful response.
