The multi-mode 12 dB/octave filter has different types of filtering that the original Moog modular synthesizers could not offer. The selector holds six types if filtering: low-pass, band- pass, notch, high-pass, low-shelf, high-shelf, bell.
The 3 knobs “Frequency”, “Resonance”, and “Gain” respectively set the cut-off frequency, the resonance, and the gain (used only for the shelf and bell)
Three modulation inputs allow the dynamic modification of the cut-off frequency.
The following images represent the different spectrum of the different filters, the cut-off frequency is constant at 500 Hz.
Low-pass 12 dB/octave | High-pass 12 dB/octave |
Notch 12 dB/octave | Bell 12 dB/octave |
Low-shelf 12 dB/octave | High-shelf 12 dB/octave |
