ThetwoOscillatorssharetwoCommonkeyboardtracking
generators,inadditiontoeachOscillator’sdedicatedkey‐
boardtrackingfortheFilterandAmp.Youcanusethese
CommonkeytracksasAMSsourcesformodulatingmost
AMSdestinations.
TheCommonKeyboardTrackparametersaresharedbythe
entireProgram,buttheactualAMSvaluesarecalculated
individuallyforeachvoice.
What does Keyboard Tracking do?
Atitsmostbasic,keyboardtrackingletsyouvarythemodu‐
lationamountasyouplayupanddownthekeyboard.This
canbeusefulformakingthetimbreconsistentacrossthe
entirerange,oradjustingparametersaccordingtopitch.
ThePS60keyboardtrackingcanbefairlycomplex,if
desired.Youcancre
atedifferentratesofchangeoverupto
fourdifferentpartsofthekeyboard.Forinstance,youcan:
• Makethemodulationincreaseveryquicklyoverthe
middleofthekeyboard,andthenincreasemoreslowly–
ornotatall–inthehigheroctaves.
• Makethemodulationincreaseasyouplayloweronthe
keyboar
d.
• Createabruptchangesatcertainkeys,forsplit‐like
effects.
Common Keyboard Tracking
How it works: Keys and Ramps
Thekeyboardtrackingworksbycreatingfourramps,or
slopes,betweenfivekeysonthekeyboard.
