The QPAS from Make Noise is an analog filter that was developed with a special focus on filtering in the stereo image. For the left and right side there are separate outputs for lowpass, bandpass, highpass and smilepass, the latter has a special resonance behavior; the inputs are also stereo. In principle, the filter core generates two peaks at the same time, which are distributed to the outputs slightly shifted to each other. Particularly noteworthy are the beautiful formant and vocal filtering that can be achieved with ease with this module. Just put for example a low tuned sawtooth oscillator on the input, add some slow triangle LFOs and enjoy the organic and lively result!
