New PWM Malevolent Synthesizer Offers Modular Flexibility and Analog Signal Path

Browse By

At Superbooth 2021, the eccentric British synth manufacturing company PWM has just unveiled their debut product, the Malevolent synthesizer, a mono synth with Eurorack-compatible patch capabilities and a pure analog signal path.

The 32 note minikey synthesizer features two analog oscillators, LFO, 2 EGs, VCF + VCA and offers a latching arpeggiator, along with pitch, velocity & gate control voltage outputs. There is the additional digital performance of the LFO via the joystick, a USB-MIDI to CV conversion within the Keys module, along with analog clock in and out.

The signal route is internally normalized, so you can simply switch on the keyboard and start playing and provides 38 3.5mm patch points, allowing you to build customized patches and play them via the keyboard.

TheĀ PWM Malevolent is still in pre-production but is expected to be available within a few months.
