sunwarper vs. Koala Sampler: Stem Splitter Showdown in a Budget Rave Bunker

Time for a proper bout. sunwarper pits Koala’s old and new stem splitters against Logic Pro, scrutinising not just the output but also the time it takes to cook up those stems. Spoiler: Logic’s stem separation is still the cleanest in the room, barely breaking a sweat while Koala’s algorithms frantically try to separate guitars from snares.

The high quality Koala splitter does show up with less mess—guitar bleed is reduced, artifacts are dialled down, and it’s less like rinsing your stems through a toaster. But when you throw Logic into the ring, you realise Koala’s still playing catch-up. If you want that razor-sharp split, Logic’s your champ, but Koala’s definitely narrowed the gap.

Here’s where things get messy—in a good way. sunwarper tears apart his track stem by stem, starting with drums. The original Koala splitter can’t keep the guitar out of the drum lane, confusing picked strings for hi-hats. The high quality mode cleans things up a bit, but guitar transients still sneak through. Logic? It mostly nails it, keeping your kicks and snares free of stray six-strings.

On vocals, the story’s similar: Koala’s new mode drastically reduces watery phasing and weird ducking, picking up more harmonies and delivering a way clearer vocal stem. Still, it can’t quite keep synths and pads from bleeding in, while Logic keeps the vocals front and centre. When it comes to “Other”—that catch-all stem for everything else—Koala’s old splitter falls apart, mixing drums, vocals, and synths into one glorious mess. The HQ upgrade is less chaotic, but still not Logic-level. Bass separation gets a boost too, but the high end comes and goes in patches. If you want the full sonic carnage, you’ll have to watch the video—words don’t do justice to the stem-juggling chaos.

Let’s call it: Koala’s new stem splitter is a big step up, but it’s not knocking Logic Pro off its throne. In busy mixes, especially those with percussive guitars and stacked layers, Koala still stumbles—misplacing sounds, losing clarity, and occasionally creating more questions than answers. Drums and vocals are improved, but Logic simply handles complex mixes with more finesse. If you’re after surgical splits, Koala isn’t quite street-weapon territory yet.

Here’s where Koala Sampler fights back. sunwarper reminds us this is a sub-£30 app, not a £200 DAW beast. For the price of a pub lunch, you get decent stem splitting, a growing effects toolbox, and a slice of the algorithmic action—no subscription strings attached (unless you’re on Logic for iPad, which will slowly bleed your wallet dry). It’s not perfect, but for portable, budget-conscious producers, Koala’s new splitter is a game-changer. If you want pristine, buy Logic. If you want quick, dirty, and affordable, Koala’s finally in the match.
