With the Forbidden Planet,Tiptop Audio presents its first multimode filter that adorns itself with the attribute vintage in sound. One may attest the Forbidden Planet its own charm and character; the resonance can scratch and bite in the best sense and the Cutoff opens and closes balanced. The filter module offers three parallel inputs which are distributed to LowPass, BandPass and HighPass . Across the three bands there is Cutoff with bipolar attenuator and CV controllable resonance. If you use several audio inputs at the same time, you get exciting filtering that virtually enchants the whole spectrum.
