Patch for paraphony. Green is a gate signal. Orange is a contoured cv such as an envelope, slewed or random cv. Cyan is the amplitude/VCA block. Magenta is the filter block. Brick Red is the pitch signal and pitch block. Purple is the waveshaping block. Blue is audio.
Paraphony is a more economical solution than polyphony. Multiple notes or voices can be played, but there will not be true polyphony because the voices are not completely independent due to sharing some common element(s) such as just one filter shaping all voices together.
