Thelow-passltershapesthetonebyselectivelylteringcertain
parts of the harmonic spectrum of the sound generated by the Oscil-
lators and the Noise generator.
CUTOFF knob [0...1023]
Thisknobisusedtosetthecutofrequency.Harmoniccontent
abovethecutofrequencywillbelteredout.
Turningtheknobtotheleftwilllowerthecutofrequency,and
turningtheknobtotherightwillraisethecutofrequency.
 IftheCUTOFFvalueissettoolow,thevolumemaybe
extremely low.
RESONANCE knob [0...1023]
AlsoknownasPeakorQ,theRESONANCEcontroladdsadditionalemphasistothe
overtonesoccurringattheCUTOFFfrequency,givingadistinctivecharactertothesound.
Turningtheknobtotherightwillincreasetheresonanceeect.
TIP
Theovertonesthatareemphasizedwillchangedependingonthecuto
frequency.Forthisreason,it’sgoodtoadjusttheCUTOFFknobwhilead-
justingtheRESONANCEknob.
When emphasizing the overtones in this way, the sound may distort de-
pendingonthecutofrequencyortheinputaudio.
