Velocity Tracking
Useyourattackvelocityasthecontrolinputforthecurrentlayer’sattacksection(thisparameter
doesn’tapplytodecayorrelease).Whenthevalueofthisparameterisgreaterthan1.000x,
attackvelocitiesgreaterthan64maketheattacksection runfaster,andattackvelocitiesbelow64
makeit
runslower.Thisgivesyourealtimeattackcontrolovertheenvelope.
Source, Depth
ThesetwoparametersworktogethertoletyouassignacontrolliketheModWheeltoaffectthe
currentlayer’samplitudeenvelopeinrealtime.ThevalueoftheSourceparameterdefineswhich
controlaffectstheenvelopesection,andthevalueoftheDepthparameterdefineshow muchthe

Note:Foreachnotetriggered,youcanonlysetthecontrollervaluethatwillscaletheDepthparameterof
