Crum Hum Generative Experimental Synthesizer

Nystrom Instruments Crum Hum

The Crum Hum from Nystrom Instruments is a synthesizer ecosystem for melody and harmony, blooming with unpredictable beauty. It offers three touch-responsive voices channeled through one of twelve expressive engines, from spanning synthetic breath to cybernetic chimes. All of this is woven into real-time, generative compositions that feel alive under your fingertips. Whether you're summoning melodic fragments or using subtle somatic sonic gestures, Crum Hum's tactile interface with built-in effects and flexible MIDI/CV connectivity feels like planting seeds in a garden of sound.

While many generative instruments can feel cold or overly abstract, Crum Hum has a unique warmth and feel. Due in part to the independently adjustable Random knob for each of the voices, this lets up to three lines of generative passages play at once with steady breath that is sometimes harmonious and other times startling. Delay, reverb, and overdrive add sculptural depth, while the onboard LFO breathes dynamic movement into your patches. A 3.5mm CV output and USB MIDI control allow Crum Hum to integrate into modular and digital setups alike. It's a deeply expressive, quietly radical instrument for those chasing something just beyond the reach of the ordinary.
