New PWM Malevolent Keyboard Offers Analog Sound, Modular Patching & Affordable Pricing

At Superbooth 2021, PWM is introducing the Malevolent synthesizer, a keyboard monosynth that features a pure analog signal path, Eurorack-compatible patchability and a relatively affordable €579.99 price tag.

The Malevolent is a portable, minikey synthesizer that features two analog oscillators, LFO, 2 EGs, VCF + VCA. The keyboard offers a latching arpeggiator, along with pitch, velocity & gate control voltage outputs.

The signal path is normalized internally, so you can just turn the keyboard on and play. But Malevolent also offers 38 3.5mm patch points, so you can create custom patches and then play them via the keyboard.
