Resonance
Resonanceemphasizesthefrequenciesaroundthe
cutofffrequency,asshowninthediagrambelow.
Whenthisissetto0,thereisnoemphasis,and
frequenciesbeyondthecutoffwillsimplydiminish
smoothly.
Atmediumsettings,theresonancewillalterthetimbre
ofthefilter,makingitsoundmorenasal,ormore
extreme.Atveryhighsettings,theresonancecanbe
heardasaseparate,whistlingpitch.

Modulating the filters
Youcanmodulatethefiltercutofffrequencyusingthe
FilterEG,theLFOs,keyboardtracking,andother
built‐inandMIDIcontrollers.Thisisagreatwayto
addarichvarietyoftonalchangetothesound.
Filter EG
TheFilterEGisamulti‐stageenvelope,whichyoucan
usetomodulatethefilteraswellasotherProgram
parameters.TheEGitselfissetupontheEGtab;the

LFO modulation
YoucanmodulatethefilterviaLFO1,LFO2,andthe
CommonLFO.Amongotherapplications,LFO
modulationofthefiltercanproducetheclassic“auto‐
wah”effect.

Keyboard Track
Mostacousticinstrumentsgetbrighterasyouplay
higherpitches.Atitsmostbasicapplication,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
theentirerang
e.
TheKROME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frequencyincreasevery
quicklyoverthemiddleofthekeyboard,andthen
openmoreslowly–ornotatall–inthehigher
octaves.
• Makethecutofffrequency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.
Fordetails,pleasesee“Howitworks:Keysand
Ramps”onpage 28oftheParameterGuide.
