Tips for using AMS
Whenadjustingsettingsforalternatemodulation,thinkof
theeffectthatyouwishtoproduce,whattypeofmodula‐
tion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pro‐
ceedlogicallyinthisway,youwillachievethedesired
effect.
