Popple Dual Filter

After Later Audio Popple

With a layout inspired by Mutable Instruments Ripples, Popple from After Later Audio is a stereo filter that provides lush filtering in the stereo field. At high resonance settings, it begins to self oscillate, allowing it to operate as a sine wave oscillator.

The resonance and primary cutoff frequency is shared between the two channels, however, each channel has a dedicated FM input for their own modulation inputs. With nothing patched into the CV inputs, the attenuverters are normalled to +2.5V. Each channel has three output channels, with two-pole band pass, two-pole low pass, and four-pole low pass filters available simultaneously. After Later Audio's Popple is a rich sounding filter that is a fantastic choice as a stereo filter or sine wave oscillator.
