Albedo by Sinevibes is a granular cloud effect plugin for KORG hardware synthesizers, and the claim most often attached to it is that it's a powerful live performance tool, specifically because of its buffer freeze function. That claim holds up. Mostly.
Quick verdict: Albedo does exactly what Sinevibes promises for poly synth players, especially on the minilogue xd and prologue. You play a chord, freeze it, and a 32-grain stereo cloud hangs in the air while you layer new material on top. That's a genuinely clever performance trick baked into hardware that can't run a DAW. The frustrating part? On the NTS-1, owners report audible pops when you move the TIME knob in real time. That's not a minor quirk on a plugin sold for live use. Buy it for a prologue or minilogue xd. Think harder before buying it for NTS-1.
The Claim: Granular Performance Power in Your KORG
Sinevibes positions Albedo as a studio-grade granular effect built to live inside KORG's digital oscillator and effect slots. The pitch is straightforward: record incoming audio into a buffer, slice it into up to 16 simultaneously looping segments, randomize their sizes and positions, and let the result bloom into a granular cloud.
Each grain gets a random size and a random start point inside the buffer. That randomness is the engine. When 16 grains are running, you're not hearing a single loop. You're hearing a smear of the original sound, shifted and overlapping in ways that feel alive.
The freeze function is the headline feature. Lock the buffer and the cloud keeps playing forever, even after the source signal stops. Layer the original input back on top and you've got a living texture bed under whatever you play next.
Sinevibes also promises smooth, noise-free parameter control, courtesy of built-in lag filters on every knob. That's the part we'll come back to, because it doesn't fully deliver across all hardware.
What Holds Up: The Freeze Is Brilliant
Start with the freeze. On a poly synth like the minilogue xd or the prologue, this is genuinely satisfying to use. Hold a pad, trigger the freeze, release the keys, and the granular cloud sustains indefinitely. It doesn't decay. It doesn't fade. It just hangs there, shimmering.
Owners who run the minilogue xd specifically report the effect enhances the synth's sound more than they expected. That makes sense: the minilogue xd's voice architecture gives Albedo richer source material to chew on, and 32 grains of stereo processing on a lush pad is a different animal from the same algorithm on a single-oscillator signal.
The true stereo processing is a real advantage. Up to 32 grains total in stereo means the cloud can spread wide. If your KORG is going into a stereo return, that width translates directly to the mix.
The color-coded interface earns its praise too. Owners report a shorter learning curve because the visual feedback is immediate. On hardware with small screens, any design choice that reduces guesswork is worth something.
Built-in preset management rounds it out. You're not programming from scratch every time you boot the device. That matters at a gig.
The TIME and DEPTH parameters are the main controls you'll live with. TIME selects grain sizes. Push it up and grains get longer, which thickens the texture and slows the sense of motion in the cloud. Pull it back and the effect gets granular in the brittle, nervous sense. DEPTH sets feedback amount, which determines how much of the granular output feeds back into the buffer. High DEPTH values let the cloud build on itself.
That feedback behavior is where Albedo stops being a reverb substitute and starts being something weirder. Owners compare it favorably to Rerun, another KORG effect plugin, and consider it the more functional of the two for this kind of textural work.
What Doesn't: The NTS-1 Problem
The popping issue on the NTS-1 is the most frustrating thing about Albedo, and it's worth being direct about it.
Sinevibes advertises lag filters that deliver ultra-smooth, noise-free parameter adjustment. That's the promise. On the NTS-1, owners report audible popping and stuttering when moving the TIME knob in real time. Not occasionally. Enough that multiple users have flagged it.
If you're buying Albedo for live performance, and the developer explicitly calls it a great performance tool, then a control that pops during performance is a real problem. Not a dealbreaker for studio use, where you set it and leave it. But for live knob-tweaking? Annoying at best, unusable at worst.
It's also worth being clear about the scope of this plugin. Albedo is KORG hardware only. It does not run in a DAW. It does not run standalone. If your KORG device isn't on the supported list, prologue, minilogue xd, NTS-1, NTS-1 mkII, NTS-3, microKORG2, it doesn't exist for you.
That's not a criticism of the design. It's just the reality you need to know before buying. Check your hardware first.
The feature set is also narrower than some owners expect going in. Users who chose Albedo over Rerun are happy with the decision. But a handful of owners report wishing they'd known more about the specific controls before buying. TIME and DEPTH are the core parameters. If you want per-grain pitch control, envelope shaping, or granular density as a discrete parameter, those aren't here, at least not as named controls in what's documented.
The TIME and DEPTH Controls in Practice
You'll spend most of your time with two knobs. That simplicity is either a feature or a frustration, depending on what you want from granular processing.
Set TIME low and play a single sustained note. The cloud will feel choppy, almost like a tremolo with personality. Each grain is short, so the randomized positions create fast transitions across the buffer. The result is nervous, glitchy, alive in a way that's hard to replicate with reverb or delay.
Now push TIME up to the longer end while a chord sustains. The effect thickens into something closer to a shimmer pad. Individual grains blur together. The transitions become inaudible. What you're left with is a smeared version of the original, trailing in all directions.
DEPTH controls how much of that processed signal feeds back into the buffer. Keep DEPTH low and the cloud reflects the input faithfully. Push DEPTH up and the effect starts self-generating, feeding on its own output. At high values this can get unstable in interesting ways, or in ugly ways. The line between the two depends on source material and TIME setting.
The freeze works best after the cloud has had a moment to develop. Trigger it too early and you're freezing a thin texture. Let it build for a few seconds, then freeze, and you have something worth sustaining.
Layering the Original Signal
One underrated aspect of Albedo's design is the ability to layer the original input signal on top of the granular cloud. This is more useful than it might sound on paper.
Without the original signal, a frozen cloud can feel disconnected from what you're playing next. The texture is there, but there's no tether to the source. Bring the original back in and the relationship between what you're playing and what's hanging in the background becomes musical rather than incidental.
For live use, this is the workflow: freeze the cloud from your pad or chord, bring the original input back, play a new melodic line over the sustained texture. The cloud evolves underneath. The new notes cut through clean. It's a surprisingly satisfying setup for a $19 hardware plugin.
Whether it replaces a dedicated granular processor in a full studio rig is a different question. It doesn't. But that's not what it's for.
Who Gets the Promised Result
Prologue and minilogue xd owners get the most from Albedo. Poly voices give the algorithm richer source material, the freeze works cleanly, and the stereo processing has room to breathe. If you perform live with either of these instruments, Albedo earns its spot in the effect chain.
NTS-1 owners need to go in with lower expectations. The TIME knob popping is a real friction point in live situations. For studio recording where you set parameters before tracking, it's less of an issue. But live? You'll either avoid the TIME knob or live with the artifacts.
NTS-1 mkII, NTS-3, and microKORG2 owners: your devices are supported, but owners haven't reported as much about specific behavior on those units. The optimization is device-specific, so results likely differ.
If you want granular processing in a DAW, on a different synth, or without KORG hardware: Albedo is the wrong tool. There's no workaround for the hardware requirement.
The Verdict
Albedo is a love-it-or-live-with-it plugin, and which camp you land in depends entirely on which KORG you own.
On the prologue or minilogue xd, it's one of the more clever additions in the KorgFX Collection. The freeze function alone justifies $19 if you perform live with either instrument. The 32-grain stereo cloud is wide, the interface is sensible, and the layering capability gives you a performance trick that's genuinely hard to replicate another way.
On the NTS-1, the TIME knob popping undercuts the live performance argument the developer makes. We'd still consider it for studio texture work on that platform, but not as a main event.
Skip it if your KORG isn't on the supported list. Full stop.
Albedo won't replace Ableton or a dedicated granular synth. It doesn't try to. But for the right synth, in the right hands, it turns a hold pedal and a freeze function into a performance tool that has no obvious equivalent in the KORG plugin ecosystem.

Alternatives to Consider
Rerun (Sinevibes, KorgFX Collection) is a stutter and sampling delay effect for the same KORG hardware platform. Owners who've used both generally consider Albedo the more capable option for granular texture work, with Rerun covering different ground. If you want stutter-style effects rather than clouds, Rerun is the call. If you want the cloud, Albedo wins.
Luminance (Sinevibes, KorgFX Collection) is a reverb plugin for KORG hardware. Owners describe it as thicker and more usable than the built-in reverb options. If your goal is ambient space rather than granular texture, Luminance is a different kind of answer to the same question. Some owners run both in a chain.
Hollow (Sinevibes, KorgFX Collection) is another reverb option in the same collection. Like Luminance, it's described as thicker than the stock reverb options on KORG hardware. The choice between Luminance and Hollow depends on character preference; both are reverb, not granular, so they don't compete with Albedo directly.
The real decision is this: if you already own a prologue or minilogue xd and you perform live or record ambient material, Albedo fills a gap that nothing else in the KORG plugin library covers. If you own an NTS-1 and you planned to work the TIME knob during a live set, go in with your eyes open about the popping issue before you spend anything.
Frequently Asked Questions
What KORG synthesizers is Albedo compatible with?
Albedo works on the KORG prologue, minilogue xd, NTS-1, NTS-1 mkII, NTS-3, and microKORG2. It's a hardware-only plugin and does not run in a DAW or as a standalone application. If your KORG device isn't on that list, Albedo won't install or run on it.
What does the freeze function actually do in a live context?
When you trigger the freeze, Albedo locks the audio buffer and keeps playing the granular cloud indefinitely from that frozen snapshot, even after the source signal stops. You can then layer the live input signal on top of the frozen texture. In practice, you hold a chord, freeze it, and play new material over the sustained cloud. Owners report this as one of the most useful features for live performance on poly synths.
Does Albedo have audible artifacts when adjusting parameters?
On the NTS-1, multiple owners report popping or stuttering sounds when adjusting the TIME knob in real time. Sinevibes includes built-in lag filters designed to prevent this, but users report the popping persists on the NTS-1. On the prologue and minilogue xd, this issue is not widely reported. If you plan to tweak TIME during a live performance on an NTS-1, be aware of the risk.
How many grains does Albedo process at once?
Albedo plays up to 16 looping grain segments simultaneously per channel, with true stereo processing giving a total of up to 32 grains running at once. Each grain has a randomized size and position within the recorded buffer, which is what produces the characteristic granular cloud texture rather than a simple loop or reverb tail.
How does Albedo compare to the other reverb plugins in the Sinevibes KorgFX Collection?
Albedo is a granular processor, not a reverb, so it doesn't directly compete with Luminance or Hollow. Those two are reverb algorithms described by owners as thicker and more usable than KORG's built-in reverb options. Albedo produces a fundamentally different sound: a smeared, randomized cloud of the source material rather than a simulated acoustic space. Some owners use Albedo alongside a reverb plugin for layered ambient results.
