Tangible Waves - Filterbank914
The FILTERBANK914 is designed after the famous Moog 914 Fixed Filterbank. It includes 12 bandpass filters with fixed center frequencies and additionally a lowpass- and a highpass filter. Control knobs for all the frequency bands allow individual mixing of the bands. This is especially useful for shaping the sound spectrum similar to acoustic instruments - they get their character by certain frequency peaks, so called "formants".
This module is different to (and not a good choice as) a multiband equalizer. The equalizer can increase/decrease certain bands in the range of e.g. -12...+12dB, with the signal unchanged with all controls in center position. In contrast, the FILTERBANK914 controls are attenuators over the full level, meaning the individual band is completely muted when the knob is turned completely counter-clockwise.
As a special feature, the module has separate outputs for "even" and "odd" bands, meaning that one output only contains the sum of half the bandpasses, the other one the remaining ones. This leads to some type of "pseudo stereo".
