Sinevibes has spent years building plugins for KORG’s logue SDK hardware line that do one thing particularly well: take a clean synth voice and make it interesting by breaking it in a controlled way. Its two newest releases, Downgrade and Malfunction, both lean fully into that idea.
Downgrade: lo-fi as a deliberate destination
Downgrade is a digital lo-fi processor built around sample-rate and bit-depth reduction — the same underlying mechanism that gave early digital samplers and consoles their gritty, aliased character, here offered as a controllable effect rather than a hardware limitation. It adds frequency aliasing and quantization noise on top of a clean signal, with a gate envelope specifically included to cut static noise at low signal levels and lag filters to keep parameter changes sounding smooth rather than stepped. It’s priced at $19 and available now.
Malfunction: filtering through a broken circuit, on purpose
Malfunction takes a different route to a related destination: it’s modeled on a tampered, circuit-bent-style low-pass filter, generating what Sinevibes describes as rough, screaming distortion that turns a clean input into “complex, expressive, and unpredictable textures full of character.” It runs 2x oversampling specifically to keep that aliasing from turning harsh rather than characterful, and includes the same kind of input gate envelope as Downgrade to prevent unwanted noise from creeping in at quiet passages. Malfunction continues a Sinevibes lineage that goes back to an earlier, differently-built Malfunction II desktop plugin from 2018 — this version is a fresh logue SDK build rather than a port of that older product.
Where they run
Both plugins install on essentially the full current KORG SDK-enabled lineup — Prologue, Minilogue XD, NTS-1, NTS-1 mkII, NTS-3, and MicroKORG2 are all supported, with the drumlogue the one notable exception. That breadth means the same two plugins can follow a single sound designer across several very differently priced pieces of KORG hardware rather than being locked to one specific instrument.
