Get to know them!

Founded on an immense passion for music and a dedication to creating fun, formidable technology, PMW reinstates its prowess with its flagship synthesizer: the Malevolent. Jam-packed with rich analog flair, this dual-oscillator, semi-modular beast is a game-changer in terms of sonic possibility and studio versatility. Dual envelopes, 38 patch points, a sync-able LFO, and USB-bus-powered connectivity will immerse you in endless sound experimentation. The inclusion of an onboard arpeggiator and VCF pushes the bounds of exploration even further, especially when paired with the Malevolent's overlapping Saw, Triangle, and Pulse oscillator functions. Best of all, the Malevolent will easily integrate into virtually any preexisting setup, lending its unmatched potential to Eurorack, modular, and standalone beginner environments. Don't be fooled: despite it's name, the kind of impact the Malevolent can have on your next project will be purely benevolent.

Trudge the depths of analog exploration

Dual VCOs with shape, pitch, and FM modulation create a nearly endless audial palette of rich analog sounds. Each oscillator on the Malevolent contains Saw, Triangle, and Pulse outputs with mix control for unique overlapping possibilities, from snappy doubling effects to chorused, warm pad arrangements. Utilizing the Malevolent's 19 output and 19 input 3.5mm jack patching system provides access to even more exploratory musical paths for endless effects and modulation experimentation. Topped off with twin ADSR-controlled envelopes and a multimode 2-pole VCF, shaping and polishing your sound on the Malevolent are seamless feats.

Inject vicious tone into your studio setup

The inclusion of MIDI I/O, Clock I/O, headphone out, line out, and USB-C connection points skyrocket the Malevolent's versatility to new heights. Other than making a great beginner standalone instrument, Sweetwater keyboard fanatics have found that this vengeful synth is an excellent sidekick for pre-existing modular setups and Eurorack builds. The bus-powered, MIDI-compatible USB interface also provides an excellent option for DAW integration and mobile-use applications — perfect for impromptu recording scenarios and environments with limited setup space. Finally, utilizing the onboard clock connection synchronizes the Malevolent's arpeggiator directly to your tempo of choice, making for effortless project integration. Whether in a professional setting or on the road, you'll benefit from the Malevolent's exponential connectivity options.

Beastly built-in clock-syncing arpeggiator

What’s a semi-modular analog synth without a potent arpeggiation engine? With six variable arpeggiator types, including Up, Down, Up/Down, Played, and Random modes, the auto-clock-capable Arp onboard the Malevolent can introduce powerful arpeggiation to your track within seconds. Work within your tempo range with interlocked rate control and MIDI connectivity for wild and immersive melodic incorporations. The arpeggiator can extend up to six octaves, making sequences from repeating bass lines to ambient, randomized plucks available at the touch of a button. Additionally, the analog/MIDI/USB-MIDI clock output opens even more doors for experimentation with the rest of your studio equipment.
