layercoverstheentirerange,theneachnoteyouplayedwouldtri gger20voices(oneforeach
layer).Youwouldonlyhearonedrumpernotebecausealltheotherlayersaretriggering
“Silence.”
Becauseofthevoice‐stealingalgorithmsinthePC3, thevoiceswouldalmost 
immediatelybecomeavailable again,sincetheyhavenoamplitude.Butforonebriefinstant,the
voicewouldbetriggered,whichcouldcauseothervoicestobecutoff.
Youcanalsocreatemulti‐velocitykeymaps—thatis,keymapsthat
willplaydifferenttimbres
dependingontheattackvelocitiesofyourNoteOnevents.Program6PopPowerPiano,for
example,usesakeymapwiththreevelocityranges.Eachkeyrangeinamulti‐velocitykeymap
containstwoormoredistinctsamplerootsthatthePC3choosesbetween,accordingto
the
