A Note About Octave Range:
WhenusingShiftKeyNumber,shiftpatternswithmorethan12stepsbegintriggeringnotesin
higheroctaves.Thisisdonebecauselongershiftpatternsuseupmoreofacontroller’srange,
andlimitthenumberofoctavesthatasinglecontrollercantr igger.Sincethelowestoctaveofa
programisoftentoolowtobemusicallyuseful,thePC3Kwillautomaticallystarttriggering
notesfromlongershiftpatternsinhigheroctaves.Thissavesroominthecontroller’srangeof
valuesfortriggeringmoreusefuloctaves.Seethetable belowforShiftPatternsteprangesand
theircorrespondingstartingoctave.
Selecting The Desired Octave Range:
Youadjustthestartingoctavemanually,usingtheAddparameteronthecorresponding
controller’ssetuppage.IntheAddfield,theadditionorsubtractionofthenumberofstepsin
yourcurrentshiftpatternwillraiseorlowerthestartingoctaveinrelationshiptothedefault
startingoctave.Forexample,
inashiftpatternwith3steps,anAddvalueof9wouldcausea
controllervalueof0tomakeShiftKeyNumber triggernotesinoctaveC3‐C‐4,3octavesabove
thedefaultC0‐C1.Addvaluesthatarenotmultiplesofthenumberofcurrentshiftpattern
steps
willchangewhichstepthepatternbeginsonatcontrollervalue0,thusoffsettingthe
relationshipbetweenallofthecontroller’svaluesandcurrentshiftpattern’ssteps.
Adjusting Controller Range:
WhenusingShiftKeyNumber,thenumberofstepsintheShiftPatternalsoaffectstherangeof
valuesthatwillcause
acontrollertotriggerashiftpatternstep,andinturnaffecttheuseful
rangeofthephysicalcontroller.Withashiftpatternof12notes,the128differentnotesthatthe
PC3Kcantriggerareevenlyspacedovertherangeofthecontroller.Patternswithlessthan12
stepswill
triggernotesineveryoctaveoverashorterrangeofthecontroller.Forexample,ina
shiftpatternwith3steps,bydefaultthecontrollervalues0to 2willtriggernotesstartinginthe
lowestpossibleoctave,andcontrollervalues27to30willtriggernotesinthehighest
possible
fulloctave.Usingasliderforthiscontroller,onlyabout1/4thofthelengthofthesliderwouldbe
triggeringnotes.Thisdecreasedusefulrangemakesthecontrollerhardertouseaccurately.To
remedythis,youcanadjustacontrollersbehaviorbyusingtheScaleparameteronthe
correspondingcontroller’s
setuppage(seeScalebelow.)AdjusttheScalevaluetostretchthe
usefulvaluesofthecontrolleracrossit’swholephysicalrange.Ascalevalueoflessthan100%
willbehelpfulforpatternswithfewerthan12steps.Experimentbyadjustingthescalevalue
untilthehighestdesirednote
istriggeredatthetopofthecontroller’sphysicalrange.SeeScale
intheContinuousControllerParameterssectionofthischapterformoredetailsontheScale
parameter.Forshiftpatternswithmorethan12steps,youwillrunoutofcontrollervalues
beforeyourshiftpatterntriggersineveryoctave.
Ifyouwanttobeabletoaccessallofthe
availableoctaves,youcanachievethisbysettingmultiplecontrollerstoShiftKeyNumber.
Next,usetheScaleandAddparametersforeachcontroller,adjustingeachtotriggerthedesired
