QPAS stands for Quad Peak Animated System. That IS a very accurate description of the new Makenoise module. In terms we all are a bit more used to: It is a quad (!) stereo (!!) multimode (HP/BP/LP…SP?) filter. In just 18 HP! Since the four filters are being run parallel it is very easy to obtain vocal-like sounds. The closest things in our store would hence also be, what we sometimes call “Formant” filters. Like (of course) the Grendel Formant Filter, the Mannequins Three Sisters, the Cwejman RES-4 /QMMF-4 and to some extent the Rossum Morpheus.
But this being a Make Noise module, you can expect an unconventional, yet very clever and playful approach. Some of you might prefer the precise editing of single filters or wish for quickly dialing in accurate formants (aka A-E-I-O-U sounds) . In that case one of the modules mentioned above might be the right one for you.
The QPAS however wants you to move away from all these abstract concepts of/and control and trust your ears and experiment. It has a simplified, but effective interface. You can control the master cutoff of all filters. Resonance creates peaks, but never reaches to selfoscillation. However you can ping it very well. To facilitate this there is a (stereo) VCA before the filters. Not after the filters like in a “normal” voice. That way the VCA doesn’t interrupt the ringing of the filters! Radiate L & R lets the peaks of the single filters move away from each other. For animating Left and Right channel independently. With the associated pot being turned clockwise the filters move from unison to further and further apart. The two inputs labelled “!!¡¡” are left intentionally vague. What is said is that they are both different, both associated with several parameters and that you can connect ANY signal to them: LFOs, audio(rate)-signals, gates…Since QPAS is not a vactrol design and the filter response is exponential, it will never be sluggish and responds exceptionally well and deep to audio rate modulations. Something you really should try when the Quad Peak Animated System arrives at our showroom (and store)!
