Sympathizer is a sound design tool centered around a tunable comb filter bank, expanding creative possibilities within this specialized area. It offers a unique approach to crafting sounds by emulating the resonance of sympathetic string clusters and producing intricate overtone cascades. This instrument delivers rich textures that go beyond traditional effects, making it ideal for musicians and producers looking to explore new sonic landscapes.

The plugin features twenty-eight independently tunable string resonators divided into three separate comb filter banks. Each bank allows detailed control over parameters such as string material, decay, stereo width, output volume, and panorama, enabling precise shaping of the sound. Users can adjust these settings individually or link banks for global changes, maintaining balance while streamlining workflow. Pitch settings are flexible, supporting MIDI note numbers, note names, or specific frequencies for tailored tuning.

Sympathizer is well-suited for creating tuned reverbs and evolving drone pads that are difficult to achieve with conventional tools. Its modulation options include controlling damper and output volume via MIDI or host automation, enhancing expressive control during performance or production. This combination of detailed tuning and dynamic control makes Sympathizer a powerful instrument for generating complex resonant textures in various musical contexts.
