Resonance Cube vs Callback Freeverb

Resonance Cube is a perpetual music machine inspired by modern composers. Tap the cube to add balls that bounce and play — each one a note in a living, evolving chord. As the music plays, the colors respond. Choose your key, chord, and instrument to shape the sound. Pick from vibraphone, piano, Rhodes, gamelan, warm pad, or crystal bowl. Let a curated chord sequence play automatically, or explore freely in Free Play mode. Add up to 24 voices — 12 melodic, 12 pad — and watch the composition build. When the cube is full, tapping begins to subtract, winding the music back down.

A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.
