Thisalgorithmsynthesizespolyphonicoctave‐upandoctave‐downcomponentoftheinputsignal
andblendsthesecomponentswiththedirectsignaltoproducethecompositeoutputsignals.The
outputlevelofeachcomponentareindependentlyadjustableformaximumflexibility.

Ontopofthisweaddedareverbalgorithmwhichsmoothsouttheresidualartifactsofthepitch‐
shiftingalgorithm.Beyondthesmoothingeffect,itturnsoutpitch‐shiftingandreverbsgoreally
welltogether,wefoundthemtobenaturalpairthatcomplementeachother.

Reverbonly?
BymutingtheSub‐OctaveandOctavecomponents,yougetonlythedrysignal+thereverb.
Nowyouhaveagreatsoundingreverbalgorithmwhichyoucanusestandalone,orpaired
withtheotheron‐boardmodulationalgorithms.
