Editing VAST Programs With KVA Oscillators
Setting KVA Oscillator Type
ThePC3comeswith22differentKVAoscillators.Thereare11highqualityanti‐aliased
oscillators(freeofdigitalartifacts,)and11oscillatorsthatexhibitsomealiasing(digitalartifacts)
inthehigheroctaves.Theanti‐aliasedoscillatorsuseupmoreDSPresourcesthantheoneswith
aliasing,buttheimprovementin
soundqualityisquite noticeable.Westronglyrecommend
usingtheanti‐aliasedoscillatorsformostapplications.
ThetablesbelowlistKVAoscillatorsbytypeandfunctionblocksize.Beforesettinganoscillator,
youmustchooseanalgorithmwhichincludesablockthatmatchestheblocksizeforthe
oscillatorthatyou
wishtouse.SeeTheAlgorithm(ALG)PageandAlgorithmBasicsinThePC3
Musician’sGuideformoreonselectingalgorithms.Onceyouhavepickedanalgorithmwiththe
desiredblocksize,highlighttheblockandusethealphawheeltoscrollthroughtheavailable
functionsuntilyoufindthe
desiredoscillator.
TheSYNCSQUAREoscillatorisan8blockoscillatorthatrequirestheuseoftwolayers(4
blockseach)andtheAltInputfeatureofcascademode.SeeThePC3Musician’sGuidefor
detailsonsettinguptheSyncSquareoscillator.
