Description
The PWM Malevolent 32-Key Semi-Modular Analog Synthesizer is a formidable blend of analog warmth and modular flexibility, designed to ignite your creative spark. With 32 velocity-sensitive mini keys, it offers an intuitive interface for musicians who crave expressive, dynamic performances.
