Introduction

Fritzisagranulareffectsdevice.Incomingaudioissampledandplayedbackinsmallsegmentscalledgrains.

Manygrainscanplaybackatthesametime,eachwithitsownsnapshotofparameters.Thissimple

mechanismcancreatecomplexandpsychedeliceffectsincludingpitchshifting,dronesynthesis,stutters,

glitches,reverbs,pitchsmearing,timesmearing,chordgeneration,textureclouds,sonicbursting,andmany

effectsthataretoostrangetobenamed.

RandomPatchGeneration



QuitepossiblythemostimportantbuttononFritzistherandompatchgenerator.Itistheiconofadienextto

thepatchloadingandsaving.InsertFritzintoyoureffectschainandkeepclickingthedietocomeupwith

endlesspermutationsofgranulareffects.

Grains

Manygrainscanbeactiveandoverlappingatthesametime.Whenagrainiscreated,itsparametersare

lockedinplace.Sowhiletherecanbeconstantparametermodulation,asinglegrainplaysbackwiththe

snapshotofthoseparametersfromwhenitwascreated.

ModulationSourceSelection.



Almosteveryparametercanbemodulated.Eachmodulationknob( )issharedbythefivemodulation

sources. 

Theactivemodulationsourceisselectedviathebuttons( )intheMODsection.Themodulationknobwill

showtheactivemodulationsources’respectivecolorunderneaththeknob.



Thecurrentamountofmodulationforeachsourceisshowninthedisplaynexttotheknob( ).

StereoHandling

Fritzhastwoseparategranularsystemsrunninginparallel,oneforeachstereochannel.Almostallparameter

modulationisalsoinstereoandcanbeadjustedwithLRPhaseStereocontrols.Grainscanfadeovertothe

otherchannelusingtheirPanparameter.TheStereoSpreadparameteradjuststheoutputstereofieldwidth.

AudioandCVInputsonthebackarenormalizedtofunctionasmonowhenonlytheleftisconnected.

InBypassmode,theinputsignalpassesthrough,unaffected,tothemainoutputsofthedevice.InOnmode,

500Hz.Whentemposyncisenabled,theavailableratesare:32/4,28/4,24/4,20/4,16/4,12/4,8/4,7/4,6/4,

RateLengthLink



EnablingtheRateLengthLinkwillcausetheLengthofgrainstobeinverselyproportionaltotheemitRate.If

theemitRategoesup,theLengthofthegrainsdecreases.IftheemitRategoesdown,thegrainLength

increases.Thishelpscreateasteadynumberofactivegrainswhentheratefluctuates.
