Volta Quadrature LFO

Volta Quadrature LFO from Matthew Davidson on Vimeo.
"Volta can be used to create a quadrature LFO. A quadrature LFO has four outputs with the phase shifted in 90 degree increments. This produces the sine, cosine, inverted sine and inverted cosine. A quadrature LFO is useful for frequency shifters, barberpole effects, quad panning, phasers and so on. In this demonstration, we'll use our quadrature LFO to modulate the waveform animation section of a Livewire Audio Frequency Generator oscillator, then we'll play with the LFO waveforms to create some syncopated timberal animation - all in sync with our project."
