Differences from other Keyboard Tracks
ThereareseveraldifferencesbetweentheAmpkeyboard
trackingandtheFilterandCommonkeyboardtracking.
Forexample,theresultsoftheRampvaluesaredifferent.As
showninthegraphic“Am p KeyboardTracking,”below,
negativeslopesaremoresteepthanpositiveslopes.
Also,theampdoesnothaveseparatecontrolofIntensity.
Instead,Intensityisalwaysfixedatthemaximumamount,
allowingkeyboardtrackingtochangethevolumefrom

Amp KTrk is also an AMS source
YoucanusethekeyboardtrackingasanAMSsourceto
modulateotherparameters,justliketheenvelopesand
LFOs.SimplyselectAmpKTrkintheAMSlistforthe

Amp Modulation
YoucanmodulatetheAmplevelbybothvelocityandan
AMSsource.
ThismodulationscalesthebasicAmplevelandAmpEG
levelparameters.Theresultingvolumeisdeterminedby
multiplyingthevolumechangesoftheampEGbyother
valuessuchasAMS.Iftheseoriginallevelsarelow,the
maximumvolumeavailablewithmodulationwillalsobe
reduced.
