YoucantelltheArpeggiatortotransposeallofthecurrentlylatchednoteseachtimeitplays
throughthem.Shiftdetermineshowmuchtranspositionwilloccurforeachcycleofnotes.For
example,ifyouhavelatchedC4andF4,andyouassignaNoteShiftof2,theArpeggiator
will
playC4,F4,D4,G4,E4,A4,andsoonuntilitreachestheLimitvalue.TheShiftvaluescanrange
from‐88to88,with0(thedefault)beingnotransposition.
Shift Limit
LimitdetermineshowfarupordowntheArpeggiatorshiftsfromtheoriginalnote.The
minimumvalue
is0,andthemaximumis60.WhentheArpeggiatorreachesthelimit,the
ArpeggiatorrespondsaccordingtothesettingfortheLimitOptionparameter.
Limit Option
Thisparameterdetermineswhat theArpeggiatordoeswhenithasshiftedthecurrentlylatched
notesup(ordown)totheshiftlimit.Stopcauses
theArpeggiatortostopwhenitreachesthe
shiftlimit.ResetcausestheArpeggiatortoreturntoitsoriginalpitchandrepeatthelatched
cycleofnotes,transposingeachcycleaccordingtothesettingsforNoteShiftandShiftLimit.If
thelimitallowsthenotestogooutofMIDI
range(forexample,ifyousetShiftto12,setthelimit
to60,andplayC6),thenthose“ghost”notesdon’tsound,buttheytakeuprhythmicspace:the
Arpeggiatorwaitsforthecycletoplayitselfoutbeforestartingover.
Unipolarmeansthatafterplayinguptothe
shiftlimit,theArpeggiatorbeginsshiftingnotesin
theoppositedirection,untilitreachestheoriginalpitch,whereitreversesagain.Todetermine
thenextnotewhenitreachestheshiftlimit,theArpeggiatorcalculatestheintervalbetweenthe
shiftlimitandwhatthenextnotewouldbeifthe
shiftlimitweren’tthere.Itthenplaysthenote
thatisthecalculatedintervallowerthanthelastnotebeforetheshiftlimit.Thesamething
happensinreversewhenthearpeggiatednotesgetbackdowntotheoriginalpitch.The
followingtablemakesthiseasiertovisualizebyshowingthe
resultofarpeggiatingonenote
(C4)inUnipolarmode,withNoteShiftsetto3STandvariousvaluesforShiftLimit.
BipolarstartsoutthesamewayasUnipolar,butduringdownwardnoteshifting,itcontinues
pasttheoriginalpitchuntilithitstheshiftlimitintheopposite
direction,whereitreversesagain.
