Smoothing
TheSmoothingTypesmoothsouttheAMSinput,
creatingmoregentletransitionsbetweenvalues.You
haveseparatecontroloftheamountofsmoothing
duringtheattack(whenthesignalisincreasing)and
decay(whenit’sdecreasing).
Lowsettingsprovidesubtlecontrollersmoothing,
creatingmoregradualaftertouch,forinstance.Higher
settingscreate
auto‐fadeeffects,transformingaquick
gestureintoalongerfade‐inand/orfade‐outevent.
Smoothingcanalsobeusedtoaltertheshapeof
programmablemodsources,suchasLFOsandEGs.
Forinstance,youcanturna“blip”intoasimple
envelopeshape,asshownbelow.

Suggestions on using AMS
Whenmakingsettingsforalternatemodulation,think
oftheeffectthatyouwishtoproduce,whattypeof
modulationwillbenecessarytoproducethateffect,
andwhatparameteroftheoscillator,filter,oramplifier
needstobecontrolled.
Next,selectasource(AMS)andsettheIntensity.If
youproceedlogicallyinthisway,youwillachievethe
desiredeffect.
Forexample,ifyouwanttocontrolaguitarsoundso
thatitapproachesfeedbackwhenyoumovethe
joystick,youmightsetupthejoysticktomodulatethe
filterfrequencyandresonance.

Creating Vibrato
YoucanuseanLFOtocreatevibrato.
LFO1/2Intensitysetsthedepthtowhichtheselected
LFOwillaffectthepitch.Withasettingof+12.00,
vibratowillproduceamaximumof±1octaveofpitch
change.
JS+YIntspecifiestheamountofvibratothattheLFO
willproduce

yourself.
