What do Downgrade and Malfunction actually do to your sound?
Sinevibes builds effects for Korg's logue SDK, the developer platform baked into every synth in the company's affordable digital line. On September 4, 2026, it added two new devices to that catalogue, both built to make a clean signal sound worse in ways producers actually want.
Downgrade is a lo-fi processor, plain and simple: it drops the sample rate and bit depth of whatever passes through it, generating the aliasing and quantization noise that budget digital gear from the 1980s and 1990s produced by accident. A gate envelope kills the hiss when there is no input, and lag filters smooth out parameter jumps so the degradation feels controllable rather than random. It costs $19.
Malfunction goes further. It is built around a low-pass filter whose internal math has been deliberately broken, the digital equivalent of a circuit-bent toy with its traces crossed. Run a sound through it and it comes out rough, hissy and, at extremes, screaming. Sinevibes runs it through 2x oversampling and adds an input gate so the distortion stays usable rather than just noisy. Company copy describes the target result as "complex, expressive, and unpredictable textures full of character."
Why is broken sound suddenly a selling point?
Deliberately wrong digital artifacts, bitcrushing, aliasing, filters that misbehave on purpose, have become their own aesthetic in house and techno production over the past few years rather than a mistake to engineer around. Lo-fi house leaned on crushed drum samples; a strain of tech house and deep-tech now leans on filters that break on command. Sinevibes is one of the few developers building tools for the actual hardware that scene already owns cheaply: Korg's logue-SDK line starts under $200 with the NTS-1, putting circuit-bent-style processing within reach of anyone, not just modular owners running a broken Game Boy through a mixer.
"If you're not a big fan of clean sounds, you might find two great new friends here."
Which Korg synths can run them, and what do they cost?
Downgrade and Malfunction run on every Korg logue SDK instrument except the drumlogue: the Prologue, Minilogue XD, NTS-1, NTS-1 mkII, NTS-3 and the new MicroKORG2 all support both plugins through Korg's own SDK installer. Downgrade is $19; Sinevibes has not published a separate price for Malfunction beyond pointing buyers to its dealer network.
This is not the update Sinevibes shipped back in July, when it made its existing logue effects cross-compatible across the same hardware line so an NTS-1 owner could finally run plugins originally bought for a Minilogue XD. Downgrade and Malfunction are new products built from scratch, the first circuit-bent-style pair Sinevibes has released for the platform.
