Additionally,thebottomlineofthispageletsyoumakeuseoftheImpactfeature,whichletsyou

Theparametersandvaluesinthefollowingparameterslist(seebelow)applytoeachofthethree
envelopesections—attack,decay,andrelease.We’lldescribethemonlyonce,sincetheir
functionsarelargelythesameforeachenvelopesection.Theonlydifference
iswithvelocity
tracking,whichisonlyavailableasaparametertocontrolattacksectionsoftheamplitude
envelope(however,youcanassignattackvelocityasthevaluefortheSourceparameterineach
ofthesections).
Thevaluesofeachoftheseparametersmultiplytheratesoftheenvelopesections
theycontrol.
Valuesgreaterthan1.000xmaketheenvelopesectionsrunfaster(theyincreasetherate),while
valueslessthan1.000xmaketheenvelopesectionsrunslower.Sayforexamplethatonthe
currentlayer’sAMPENVpageyouhadsettheDecaysection’stimeat2.00seconds,anditslevel

at0%.Thissetsthelayer’samplitudetofadetos ilence twosecondsafterthecompletionofthe
lastattacksegment.Thedecaytimeistwoseconds;thedecayrateis50%persecond.Nowifyou
selecttheENVCTLpageandsettheDecayAdjustparametertoavalue
of2.000x,you’ve
increasedthedecayratebyafactoroftwo,makingittwiceasfast.Therateincreasesto100%per
second,andthedecaytimeisnowonesecondinsteadoftwo.
Note:Since0multipliedbyanynumberequals0,theenvelopeparametersonthispage
willhavenoeffect
onanyAMPENVsectionssetto0seconds.AwayaroundthisistochangeanyAMPENVsectionssetto

giveyourealtimecontrolovertheenvelope.Itis,however,agoodwayto adjustthenatural
