PWM(PulseWidthModulation)[Aliased(notrecommended)]
Thisoscillator’sdistinctiveparameterisPWMWid,whichadjustspulsewidthfromvaluesof1‐
99.WithPWMWidsettoavalueof50,PWMproducesasquarewave.ThefurtherthePWM

SYNCSAW
SyncSawconsistsoftwosawwaves,onethatyouhear(theslave)andonethatcontrolstheslave
(themaster.)Thisoscillator’sdistinctiveparameterisSyncOff,whichcontrolstheoffsetofthe
slaveandmasterwaves.WithSyncOffsetto0,themasterhasnoeffectonthe
slave.Whenan

Offsetscausetheslavetorestartitscycleinthemiddleofnormalsawtoothcycles,whichcauses
