V.A.S.T. and KB3 Programs
ItisimportanttounderstandthedifferencebetweenV.A.S.T.programsandKB3programs.
V. A . S . T. programscontainupto32layers.Eachlayercontainseithersamples(mostoftenused
torecreateconventionalinstrumentsounds,)orKVAoscillators(usedforvirtualanalog
synthesis.)Eachlayerispresettobetriggeredbythekeyboard
inspecificrangesandvelocity
levels.Theabilitytotriggersomanylayersresultsindetailedandmorerealisticprograms.Each
layerisalsoroutedthroughsophisticateddigitalsignalprocessing(DSP)algorithmswhich
shapethetoneandotherbehaviorsofthesounds.
KB3programsuseamuchdifferentarchitecture.Thereare
nolayersoralgorithms,justasetof
oscillators(designedtoemulatethetonewheelsinaHammondOrgan)thatstartrunningas
soonasyouselectaKB3program.We’vedoneextensivetestingandanalysiswithseveraltone
wheelorgans,andcreatedourownmodelstoemulatetheuniquetone
wheelsound.Each
oscillatoroperatesindependently,andhasitsownpitchandamplitudesettings.The
oscillators—we’llcallthemtonewheelsfromhereon—aredividedintoanupperandlower
group.Theuppertonewheelsuse thesamplesinthe PC3LE’skeymapstogeneratesound,while
thelowertonewheelsusesine
waves.
KB3programsaredifferentenoughfromV.A.S.T.programsthatweusethetermKB3modeto
describewhat’sgoingonwhenyouplay aKB3program.WheneveryouplayaKB3program,
youareinKB3mode.YoucanfindKB3programsbypressingtheOrgancategorybuttonwhile
