OPERATIONS MANUAL • FIRMWARE V1.0
FUNDAMENTALS
 TheHertzDonutMarkIIIisacomplexoscillatorutilizingtheī˜ƒī›€nestdigitalsoundsynthesistechniquesfromthe
mid-1980s.Itusesacombinationofphasedistortionandthru-zerofrequencymodulation(FM),andthesynthesis
algorithmprovidesaccesstoanauxiliaryoscillator/outputaswellasasimpliedcontrolforthetotaleffectofthe
modulationbus.Anaudioinputactsasafull-bandwidthsourceformorecomplicatedmodulationsinvolvingexternal
devices.Theunisondetunefunctionoffersbeautifulglasschorusvoicing,andthephasedistortionparametershave
beenchosentoprovidecoherenttimbrewarpingevenunderheavyfrequencymodulation.Themodulecontainsthe
MarkIIImorphingpresetmanagerwhichfacilitatesstorageandperformanceofallmoduleparameters.
GETTING STARTED
 Whenthecoarsetuneissettoitsminimumpositionandtheī˜ƒī›€netuneissettothemiddleposition,thegenerated
frequencywillbe16.35hz(noteC0)withnoexternalvoltagesapplied.Patchinga1voltperoctavetunedsequencer,
quantizer,orkeyboardvoltageintothisjack(suchastheSTILLSONHAMMERorARGOSBLEAK)willchangethe
oscillator’sfrequencytothedesirednote.IfthecontrolvoltageissetsothatC0isequivalenttoavalueof0volts,then
thenotenamesshownontheHertzDonut’sdisplay(andthegeneratedfrequency)willmatchtheinputvoltage.Listen
totheresultsofyourpatchprogrammingatanyofthejacksintheOUTPUTsection.TheMAINoutputwillcontainthe
moststraightforwardexampleofyourprogramming.TheAUXoutputbehaviorisselectableinamenu.TheMIXoutput
isasimpleanalogcombinationofbothoutputs.
SCREEN SAVER
TheHertzDonut’sdisplayisanOLED.Itissettoabrightnesstoprovidethebestbalancebetweenvisibilityandlong
life.TopreservethelifeoftheOLED,itwillturnoffifabuttonorencoderisnotusedfor10minutes.Toturnitbackon,
pressabuttonorturntheencoder.
MK III MENU SYSTEM
 MostfunctionblocksinIndustrialMusicElectronicsmoduleshavehiddenmenusassociatedwiththem.Toaccess
them,holddowntherotaryencoderbuttonandpushtheassociatedbutton.Themenuwillappearonthedisplay.Turn
theencodertoselectthedesiredmenuitem.Pushtheencodertoselecttheitem,andturntheencodertochange
theselecteditem.Pushtheencoderbuttonagaintoenteryourselection.Exitthemenubypressinganyoftheother
buttons.Ifabuttondoesnothaveamenuassociatedwithit,thenthebuttonpresscombinationwillusuallyinvoke
anothershortcutfunction.
CV INPUTS
 MostCVinputsontheHertzDonutacceptfull-scale,
bipolarcontrolvoltageswitharangeof+/-10v.Theresponse
ofthevariousinputsarescaledtoprovideamusically
usefulrangeofmotionwithinthetypicalrangeof+/-5V,
withadditionalreactivityfaroutsideofthisrange.The
attenuvertersuseanonlinearcurvetoallowatypicalcontrol
voltagetosubtlymodulateasmallrangeoftheparameter,or
full-swingtravelwithouttheuseofexternalamplication.
PRIMARY OSCILLATOR
 Thetwofrequencycontrolssetthecoarseandī˜ƒī›€netuningfrequenciesoftheoscillator.Theirspecicfunctions
maybereversedintheMAINī˜ƒā€œGLOBALā€ī˜ƒOPTIONSmenubypressingtheEncoderandEXTbutton,scrolldownto

ā€œReverseā€ī˜ƒassignsthelargeknobtoFineTuneandthesmallknobtoCoarseTune.
 Thefrequencyoftheoscillatorissetasacombinationofthecoarseandī˜ƒī›€nemanualtuningcontrols,thevoltage
presentattheī˜ƒā€œ1V/Octā€ī˜ƒandī˜ƒā€œCVā€ī˜ƒjacks,theOCTAVESHIFTparameter(inthemenu),andtheloadedpresetdata(if
ALLPARAMSisenabled.)Theī˜ƒā€œCVā€ī˜ƒjackacceptsabipolarcontrolvoltage,suchasavibratoLFO.Itisattenuatedby
thenearbyī˜ƒā€œattenuverterā€ī˜ƒknob.
PHASE DISTORTION
 Theprimaryoscillatorproduces a
sinewavewithnoharmoniccontent
thatismodiedbytheī˜ƒā€œFOLDā€ī˜ƒ
controltocreateamorecomplicated
waveform.Therearethreewaveform
parametersthatmaybemodiedby
thiscontrol.Theī˜ƒā€œFOLDSELECTā€ī˜ƒ
buttonchooseswhichparameteris
modiedbytheFOLDknob(thecurrentselectionisshownonthedisplay).Intheoscillatormenu,theī˜ƒā€œCVDestinationā€ī˜ƒ
parameterchooseswhichparameterisaffectedbytheFoldCVinput.WhenyouchangetheFOLDSELECT,the
currentknobpositionforthepreviouslyselectedparameterisī˜ƒā€œfrozenā€,andyoucanthenusethesameknobtoenter
thevalueforthecurrentlyselectedparameter.Allthreewaveformparametersarestoredinapresetandcanbe
morphedcontinuouslybythepresetmanagerforamode-less,3-dimensionaltimbrespace.Thedisplayshowsagroup
ofthree"virtualsliders"inthecenterthatcommunicatesthecurrentsettingofallthreeparameters.Whenallthree
parametersaresettozero,asinewaveisproduced.
 Theī˜ƒī›€rstanddefaultFOLDsettingisthePhaseDistortion,shownasī˜ƒā€œPDistā€ī˜ƒonthedisplay.Thismodiesthe
ā€œrampā€ī˜ƒthatisusedtogeneratethe
sinewave,addingbreakpointsand
reversals.Thiscausesasmoothlinear
outgrowthofadditionalharmonics,
reminiscentofthesynthesisofsimple
brassinstrumenttones.Pastthe12
o’clockpositionontheknob,theī˜ƒī›€rst
harmonicinthesignalbecomesvery
strong,andcreatesaperceivedī˜ƒā€œoctave-upā€ī˜ƒeffect.Therestrainedyetcharacterfulnatureofthisparametermeansthat
itperformswithexceptionalclarityevenunderheavyfrequencymodulation.
UMBRAGE
 Thisisthesecondparameter
oftheFOLDSELECTsetting.When
selected,thedisplaywillreadī˜ƒā€œUmbrā€ī˜ƒ
onthetopline.Itisbasedonthe
ā€œfractalā€ī˜ƒwaveformdistortionfrom
previousversionsoftheHertzDonut.
Itcausessmallleaf-andbranch-
likestructurestogrowoutfromtheslopesofthewaveform.Thiscreatesaī˜ƒā€œfuzzā€ī˜ƒtypeofdistortionwithabiastowards
higherfrequencies,consonantwiththebasefrequencyofthewaveform.
RESONANCE
 ThisisthethirdparameteroftheFOLDSELECTsetting.Whenselected,thedisplaywillreadī˜ƒā€œResoā€ī˜ƒonthetop
line.Itisinspiredbytheī˜ƒā€œvirtualresonanceā€ī˜ƒwaveformsofhistoricalPhaseDistortionsynthesizers.Itcausesaseriesof
resonantpeakstorisethroughoutthewaveformasthecontrolisincreased.Whenyouroriginalwaveformisclosertoa
simplesinewave,theeffectsoundsjustlikearesonantī˜ƒī›€ltersweep.Withmorecomplicatedwaveforms,theresonance
effectsoundsclosertoclassicoscillatorsyncsweeps.Thiseffectislessstableunderheavyfrequencymodulation.
