- | This is the wave shaper board for our [[paper_synth:ps110_vco|PS110 VCO]]. The waveshaper converts saw wave to sine, square and triangular waves. It also ads and input and control for linear frequency modulation and pulse width modulation for square output. | + | This is the wave shaper board for our [[paper_synth:ps110_vco|Paper-Synthesizer 110 - VCO]].
