After Later Audio Popple

Multimode stereo filter

8 HP Eurorack module

An 8 HP multimode stereo filter based on the Mutable Instruments Ripples V1 filter section.

Features

• Two separate audio paths.
• Each channel has an attenuverted cutoff-CV input normalled to a 2.5 V signal.
• High resonance settings enable self-oscillation.
• It can also act as a dual sine-wave oscillator.

Controls & Jacks (16)

• Resonance— Sets the shared filter resonance for both audio paths; high settings allow self-oscillation.
• Left Band-Pass Output— Left-channel band-pass filter output.
• Left 2-Pole Low-Pass Output— Left-channel 2-pole low-pass filter output.
• Left 4-Pole Low-Pass Output— Left-channel 4-pole low-pass filter output.
• Right 2-Pole Low-Pass Output— Right-channel 2-pole low-pass filter output.
• Right Band-Pass Output— Right-channel band-pass filter output.
• Right Cutoff CV Amount— Attenuverts the right-channel cutoff CV input and is normalled to 2.5 V when that CV input is unpatched.
• Left Cutoff CV Amount— Attenuverts the left-channel cutoff CV input and is normalled to 2.5 V when that CV input is unpatched.
• Left Audio Input— Audio input for the left filter path.
• Resonance CV Input— CV input for the shared resonance control.
• Cutoff— Sets the shared cutoff frequency for both filter channels.
• Right 4-Pole Low-Pass Output— Right-channel 4-pole low-pass filter output.
• Left Cutoff CV Input— Cutoff-frequency CV input for the left channel; its associated amount control is normalled to 2.5 V when unpatched.
• 1V/Oct Cutoff CV Input— Shared 1V/Oct cutoff-frequency CV input for both filter channels.
• Right Audio Input— Audio input for the right filter path.
• Right Cutoff CV Input— Cutoff-frequency CV input for the right channel; its associated amount control is normalled to 2.5 V when unpatched.
