Throbber - Voltage-controlled amplifier plugin

In depth

A closer look at Throbber

The Throbber VST plugin consists of an LFO driving a voltage-controlled amplifier (VCA) or multi-mode filter (VCF). Its controls should be pretty much self-explanatory. The Mode knob selects among VCA, filter, flanger, and bi-flanger modes. A flanger is fundamentally an LFO-modulated delay mixed with a constant delay; in regular flanger mode the LFO modulates both the left and right channels equally, while in bi-flanger mode the left and right channel modulations are inverted; one channel will "lead" the fixed delay while the other lags behind it. When operating in VCA mode, the Effect knob controls the overdrive distortion of the amplifier. In filter modes, it controls the filter resonance. In flanger modes, it controls the amount of feedback into the flanger delay lines. The Bias control sets the average / center cutoff frequency or gain which is modulated by the LFO. In addition to the usual analog synth waveshapes, Throbber supplies a handful of Nominal Fourier Synthesis waveforms via the Shape control.
