Popple by After Later Audio is a true stereo multimode filter based on the first version of the Mutable Instruments Ripples filter. The module offers stereo outputs for bandpass, 12dB and 24dB lowpass, the combination possibilities in stereo patches alone promise interesting filtering. Due to the normalized audio inputs, a mono signal can be used at the left input, which is internally converted to Stereo. Cutoff and resonance are set uniformly for both sides, the modulation of the cutoff parameter can be set separately for both sides with positive and negative intensity. Control voltage inputs without attenuators are available for Keytracking and resonance.
