Keyboard Track
Mostacousticinstrumentsgetbrighterasyouplay
higherpitches.Atitsmostbasic,keyboardtrackingre‐
createsthiseffectbyincreasingthecutofffrequencyof
alowpassfilterasyouplayhigheronthekeyboard.
Usually,someamountofkeytrackingisnecessaryin
ordertomakethetimbreconsistentacrossth
eenti
re
range.
TheKRONOSkeyboardtrackingcanalsobemuch
morecomplex,sinceitallowsyoutocreatedifferent
ratesofchangeoveruptofourdifferentpartsofthe
keyboard.Forinstance,youcan:
•Makethefiltercutoffincreaseveryquicklyoverthe
middleofthekeyboard,andthenope

owly–ornotatall–inthehigheroctaves.
•Makethecutoffincreaseasyouplayloweronthe
keyboard.
• Createabruptchangesatcertainkeys,forsplit‐like
effects.
How Key Track works: Keys and Ramps
Thekeyboardtrackingworksbycreatingfourramps,
orslopes,betweenfivekeysonthekeyboard.The
bottomandtopkeysarefixedatthebottomandtopof
theMIDIrange,respectively.Youcansettheother
threekeys–namedLowBreak,Center,andHigh
Break–tobeanywhereinbetween.
ThefourRampva
luescontroltherateofchange
betweeneachpairofkeys.Forinstance,iftheLow‐
CenterRampissetto0,thevaluewillstaythesame
betweentheLowBreakkeyandtheCenterkey.
Youcanthinkoftheresultingshapeasbeingliketwo

Centerkey(themainhinge),thekeyboardtrackinghas
noeffect.Thetwofoldingdoorsswingoutfromthis
centerpointtocreatechangesinthehigherandlower

AMS Modulation
InadditiontotheEG,LFOs,andKeyTrack,youcan
usetwoAMSsourcestomodulatethefilters.For
instance,youcouldusetheribbontochangethe
brightness,orusetheAMSoutputofaWaveSequence.
Using the Amp section
TheAmpsectionincludescontrolsforvolume,pan,
andthedrivercircuit.Youcancontrolthevolume
usingtheAmpEG,LFO1/2,KeyTrack,andvelocity,
alongwithotherAMSsources.
EachOscillatorhasitsownAmpsection:Amp1for
OSC1,andAmp2forOSC2.
Background: what does “Amp” mean?
Differentsoundshavecharacteristicshapestotheir
volumelevels.
Forexample,thevolumeofapianonotebeginsata
highvolumetheinstantyouplaythenote,andthen
decreasesgradually.
Thevolumeofanorgannote,ontheotherhand,
remainsconstantaslongasyoucontinuepressingthe
key.
Thevo

canbevariedduringthenotebythemusician(i.e.,by
