There’s a specific texture that granular synthesis should be able to make — grains hitting on the beat while the audio underneath them drifts at a completely different speed. In practice, getting there in most tools means fighting the interface or accepting compromises. Christian Alexander, a solo developer and producer from Colorado, spent long enough hitting that wall that he eventually stopped looking for the tool and built it.
The Core Idea
SingleGrain separates grain repetition rate from sample playback speed. That’s the whole pitch. You sync the grain timing to your host BPM, then run the audio itself slow, fast, or in reverse underneath it — independently. It sounds like a subtle distinction until you actually try to recreate it elsewhere. Most granular plugins either couple these parameters directly or bury the workarounds deep enough that the creative momentum dies before you get there.
The Speed knob controls sample playback rate. The Length parameter, when Synced, locks grain timing to BPM divisions including triplets. They’re separate controls with separate behavior. That’s it — but that’s the point.
Reverse Playback Without the Chaos
Reverse granular is one of those features that sounds great in demos and falls apart in practice because the grain start position keeps drifting as the sample plays backward. SingleGrain’s Lock Pos switch fixes that: when enabled, the grain start position stays pinned to wherever you set it even when speed is negative. It’s the kind of small decision that only gets made by someone who burned time on the exact problem it solves.
The Sync toggle on the Length parameter also changes behavior specifically for negative speeds — not just a checkbox that ignores direction — which suggests the reverse workflow was designed in from the start, not bolted on.
What Else Is in There
The modulation system is deeper than the price suggests. LFO shapes are fully custom-drawn: red dots set start positions, yellow dots adjust curve slope, pink dots add or remove points. Shapes can be saved and reloaded as files. Each LFO can run free, as a one-shot envelope, or synced to BPM — and you can drag an LFO onto any parameter knob directly, with a secondary LFO available to modulate the depth of the first.
The M1 macro knob maps to multiple parameters simultaneously, which makes SingleGrain usable as a live performance instrument rather than just a studio tool. Real-time audio input is supported with low-latency grain processing, so you’re not limited to pre-loaded samples. The plugin ships with 80+ factory presets across pads, textures, percussion, and sound design categories.
Where It Fits in 2026
The granular plugin market is genuinely crowded right now. Baby Audio shipped Grainferno in March with per-grain processing and audio-rate modulation. Sound Particles released GrainDust with four independent granular layers. Delta Sound Labs showed XStream at NAMM, and last but not least, there’s the beloved Efx FRAGMENTS — Arturia’s take on granular synthesis. Against that backdrop, SingleGrain doesn’t try to out-feature anyone — it focuses on a specific, well-defined use case and prices itself accordingly at $29 one-time.
Perhaps I’m wrong, but there’s something clarifying about a plugin whose unique feature can be explained in two sentences. Whether that focus holds up under extended use is the real question — but as a first commercial release from a solo developer, the design logic is unusually coherent.
