Attack [00...99]
ThissetshowlongtheEGtakestomovefromtheStartlevel
totheAttacklevel.
Forthefastestpossibleattacktime,youcansettheStart
levelto+99;inthiscase,theEGwillstartinstantaneouslyat
itsmaximumvalue.
Decay [00...99]
ThissetsthetimeittakestomovefromtheAttacklevelto
theBreaklevel.
Slope [00...99]
ThissetshowlongtheEGtakestomovefromtheBreak
leveltotheSustainlevel(whichforthePitchEGisalways
0).OnceitreachestheSustain,theEGwillstaythereuntil
note‐off,unlessitisresetviaAMS.
Release [00...99]
ThissetshowlongittakestheEGtomovefromtheSustain
leveltotheReleaselevel.
Level
Eachofthefourlevelscanbeeitherpositiveornegative.
Positivelevelswillmakethepitch(orotherAMSdestina‐
tion)goupfromitsprogrammedvalue;negativelevelswill
makeitgodown.
Notethat,unliketheFilterandAmpEGs,thePitchEG’s
SustainLevelisalways0.
Start [–99...+99]
ThissetstheinitialEGlevelatnote‐on.
Attack [–99...+99]
ThissetsthelevelattheendoftheAttacktime.
Break [–99...+99]
Break,shortforBreakPoint,setsthelevelattheendofthe
Decaytime.
Release [–99...+99]
Thissetsthelevelat theendoftheReleasetime.

Forthesakeofsimplicity,mostofthediagramsinthisman‐
ualshowenvelopesasbeingmadeoutofstraightlines.In
actuality,though,envelopesaremorelikelytobemadeout
ofcurves.
Inotherwords,eachsegment’slevelwillchangequicklyat
first,andthenslowdownasitap
proachesthenextpoint.
Thistendstosoundbetterthanstraight,linearsegments.

Pitch EG Curve
Whenyo
uchangethecurvature,theEGtimesremainthe
same.However,greatercurvaturewilltendtosoundfaster,
becausethevaluechangesmorequicklyatthebeginning.
Different curve settings for up and down
Youmayfindthatdifferentamountsofcurvaturearesuit‐
ableforsegmentswhichgoupandsegmentswhichgo
down.
Forinstance,acurveof3isagooddefaultsettingfor
upwardsegments,suchasAttack.Ontheotherhand,a

Attack [0L (Linear), 1...9, 10E (Exp/Log)]
ThissetsthecurvatureoftheAttacksegment‐thetransition
fromtheStartleveltotheAttacklevel.
Decay [0L (Linear), 1...9, 10E (Exp/Log)]
ThissetsthecurvatureoftheDecaysegment‐thetransition
fromtheAttackleveltotheBreaklevel.
