The Cherry Audio VM Rackmode String Filter comprises 36 high-Q parallel bandpass filters arrayed throughout the musical range. The original unit was intended to mimic the multiple static resonances of a stringed instrument body such as the violin or cello. When simple waveforms (especially solo waveforms) are played through it, the String Filter imparts a woody richness to the sound making it sound more "stringlistic."

This module may be demoed with the full Rackmode Module Collection demo for up to seven days. This demo will play white noise periodically, but is otherwise unlimited.
