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.

    • Selectable sync rates when clock detected
    • Rate / sync control
    • Latch
    • 6 Octave range
    • Analogue / MIDI / USB-MIDI Clock output when arpeggiator is running

Pricing and Availability

The PWM Malevolent is still in pre-production, but is expected to be available within a few months, with the following pricing:

  •  £499.99 inc. VAT
  • €579.99 inc. VAT

No US pricing has been announced, but the €579.99 (inc VAT) price would translate into about $550 USD. See the PWM site for more info.

    1. Good luck with that

      It’s clearly obvious at this stage that the majority of users don’t give a fuck for full size keys

      They would rather have the extra space – space is far more expensive than synths

      Probably because most synth heads are noodlers (like myself) and not trained keys/piano players

      I presume synth makers do the market research before they make the synths

      Small synths (and in effect mini keys) are cheaper to make and probably shift more units than big synths

  1. It is amusing to see how products have developed from discrete Eurorack modules to full patchable instruments with keyboards. At this rate, they should be going polyphonic next year and perhaps we’ll get patch memories in 2023. We’ll be back to 1984 in no time!

  2. Looks nice but €580 is way above the “affordable” range for a decent mono synth these days

    You could have a Deepmind 6 for far less – might not be patchable but doesn’t really need it

  3. Minikeys again. What a pitty. I don’t understand. If you want to play keys use normal size, if you don’t use a module instead.
