After Later Audio Waves is an exact hardware replica of the Mutable Instruments Ripples V2 module. Ripples delivers a classic, big-sounding analog four-pole filter in a small 8-HP package, continuing Mutable Instruments’ lineage of warm and tasty filters started by the Shruthi SMR4 mkII and 4-Pole Mission. 3 filter modes are available: 2-pole band-pass, 2-pole low-pass, and 4-pole low-pass. Self-oscillation is available for all modes and produces a clean sine-wave on the LP4 output. Unlike many classic 4-pole designs, this filter does not suffer from “loudness drop” when resonance is increased. The resonance loudness compensation circuit brings a slight tone coloration reminiscent of the Roland SH/Jupiter filters, with a very round and “liquid” resonance. The 4-pole low-pass output is additionally sent to a VCA. This makes Ripples a good final stage module for an inexpensive/space-constrained subtractive synthesis synth voice. Width: 8HP Depth: 25mm Power: 35mA @+12V / 35mA @-12V
