CableGuys has just released FilterShaper, a new VST plug-in that aims to "bring life to your sounds and loops".
FilterShaper enables you to draw any curve, assign it to its 4 LFOs and use them to modulate filter cutoff and filter resonance of its filters, or simply modulate the volume. ts drawing possibilities are ultra-flexible, yet easy to use. You can draw any curves you like shaping hard-synced or analogue-sounding rhythms. Create interesting rhythmic strings, shape a bass sound, destroy vocal recordings, create vivid shaker rhythms out of white noise, etc. You can go from subtle changes to extreme modulations, from little sound corrections to nicely filtered rhythmic loops. Its various filters can be set to drastic values from zero resonance up to self-oscillation.
FilterShaper is available as a VST effect plug-in for Windows. The demo version gives you full functionality with the only limitation being that only one instance of the plugin can be used at the same time, so it is essentially free unless you want to use more than one instance in a project. The full license can be purchased for €29 / $44.
