LFO
LFO:LowFrequencyOscillator
TheLowFrequencyOscillatorcreatesarepeat-
ingcyclicalsignal.Youcanchooseoneofthree
LFOwaveforms.
Dependingonitstarget,theLFOcanprovide
vibrato(PITCH);TonalchangestotheOscillators(SHAPE);orWah-Wah(CUTOFF)
eects.
WAVE switch [ , , ]
TheLFOcanbesettoasquarewave( ), a triangle wave ( ), or a sawtooth wave
(
).
MODE switch [BPM, SLOW, FAST]
SpeciestherangeofchangeandactionfortheLFOfrequency.
BPM:TheLFOfrequencysynchronizeswiththeBPMofthearpeggiator.
SLOW: TherangeofchangefortheLFOfrequencywillbefrom0.05Hz–28Hz.
FAST:TherangeofchangefortheLFOfrequencywillbefrom0.5Hz–2.8kHz.
RATE knob [0...1023 / 4, 2, 1, 0, 3/4...1/64]
TherateknobadjuststhespeedoftheLFO.
TurningtheknobtotherightwillincreasetheLFOspeed.
INT knob [0...511]
TheINTknobadjuststheintensityoftheLFO.
TurningtheknobtotherightwillincreasetheLFOintensity.
TIP
WhenturningtheINTknobwhileholdingdowntheSHIFTbuon,the
LFOwaveformwillbeinverted.Theseingrangeis0–-511.
TARGET switch [CUTOFF, SHAPE, PITCH]
SelectswheretheLFOmodulationwillbeapplied.
CUTOFF:ModulationisappliedaccordingtotheVCFCUTOFFknobseing.
SHAPE:ModulationisappliedaccordingtotheSHAPEknobseingfortheoscilla-
tor,whichissetin“LFOTargetOSC”(p.48)ofPROGRAMEDITmode.
PITCH:ModulationisappliedaccordingtothePITCHknobseingfortheoscilla-
tor,whichissetin“LFOTargetOSC”(p.48)ofPROGRAMEDITmode.
