The Doepfer A-128 is a classic Fixed Filter Bank, with volume controls for each bandpass filter. It has 15 different bands spread across the hearing spectrum, spaced for particularly musical timbral shaping. The output signal mixes all the bands together depending on their volumes. Great as a last module for equalization, or patched in between a feedback patch for shifting timbres and pitches within the feedback.
