    Source

Build quality

  • Users mention solid build quality, though the keys feel subpar compared to other components.

    Source

Features and functionality

  • The LFO is reported as limited, with half its knob range having minimal effect, prompting some to use external LFOs for slower sweeps.

    Source
  • The synth's filter can become unpredictable, with wild results when drive and resonance are added.

    Source
  • Total disassembly is mentioned as a challenge; the synth's native pitch CV requires external solutions due to a design flaw.

    Source

Use cases and applications

  • Ideal for aggressive, distorted sounds but can also produce softer tones by adjusting resonance.

    Source

User experience

  • The synth reportedly sits well in mixes without much effort, making it versatile for various musical contexts.

Critic Reviews

PWM Malevolent review | MusicRadar

musicradar.com

PWM's Malevolent synthesizer delivers a raw, characterful sound and a user-friendly interface that encourages creativity. While its vintage design is charming, it lacks modern features like patchable utilities and sync options for the LFO, which can limit versatility. The joystick control, while nostalgic, raises usability questions. Overall, it's a bold debut that excels in sound design, particularly for aggressive basslines, but may not satisfy those seeking extensive modulation capabilities.

positive

PWM Malevolent

soundonsound.com

While the PWM Malevolent is not as "evil" as its name suggests, it excels as a compact, semi-modular analog synthesizer with impressive patching potential and a gritty sound. Its standout features include a robust control section and a powerful filter that invites experimentation. However, the single LFO feels limited, and the mini-keyboard may frustrate some players. Despite these drawbacks, the Malevolent's raw sonic capabilities make it a worthy addition to any studio, especially for those eager to explore its modular potential.

Sonic LAB: PWM Malevolent Synthesizer Review

sonicstate.com

The PWM Malevolent synthesizer delivers a hot, driven sound and boasts a unique, character-filled analog design. With its Sallen-Key filter and joystick control, it offers creative potential, but beware: running it too hot can lead to uncontrollable resonance and a noisy signal at lower oscillator settings. Parameter scaling can be finicky, making precise modulation adjustments a challenge. While the build quality is appreciated, some design choices, like the joystick's portamento function, may not suit every player's style. At around $520, it’s a compelling option for those seeking a gritty analog experience, but it’s not without its quirks.

First Look Review: PWM Malevolent – semi-modular analog synthesizer - gearnews.com

gearnews.com

The PWM Malevolent is a bold entry into the semi-modular synth market, delivering brash and gritty sounds that appeal to adventurous sound designers. Its compact design, extensive patchability, and Eurorack compatibility make it a versatile tool for creative exploration. However, the build quality feels a bit cheap, with wobbly knobs, and some may find the mini keys limiting. Additionally, the lack of LFO sync and modulation options can frustrate those seeking more refined control. Ultimately, the Malevolent shines with its unique character and FM capabilities, but it may not suit everyone’s taste—those who prefer polished sounds should tread carefully.

Dirty.

The PWM Malevolent is a great semi modular analog synth. If you want clean sounds, this isn't the synth for you, this is fat and dirty with tones of drive to add.
