LFO RATE: Adjusts the LFO RATE (and Clock Divisions when synced to
MIDI) from 0.05 Hz to 50 Hz.
MIDI CC#: MSB-15, LSB-47
LFO SHAPE: Selects from Sine, Triangle, Square, Ramp, Sawtooth, Sample
and Hold, and Smooth Sample and Hold modulations as well as
OFF (no
LFO). MIDI CC#: 17
SYNC: When SYNC is on, the LFO RATE is linked to MIDI clock and can be
set to a
CLOCK DIVISION of the current MIDI BPM. MIDI CC#: 78
LFO AMOUNT: Determines the amount of LFO modulation of the Delay
TIME. MIDI CC#: MSB-16, LSB-48
DUTY CYCLE: Adjusts the duty cycle for the square wave LFO shape from
0% (fully off) to 100% (fully on). Low percentage duty cycle is mostly off
with a short high going pulse. High percentage duty cycle is mostly on
with a short low going pulse. With the editor’s knob at 12:00 both high and
low states are equal duration (50% duty cycle = perfect square wave).
Note: Affects square wave LFO shape only. MIDI CC#: MSB-20, LSB-52
PHASE RESET: Resets the LFO phase to zero (the start of the waveform)
when pressed.
MIDI CC#: 72
CLOCK DIVISION: Sets the length of one LFO cycle to a defined number of
beats at the MIDI tempo. For example. if the
LFO CLOCK DIVISION is set
to one whole note, the LFO will complete one cycle in four beats. See MIDI
CLOCK DIVISIONS table for more information. MIDI CC#: 79
OVERVIEW OF LFO WAVEFORM CHARACTERISTICS
SINE : A periodic wave that smoothly transitions from peak to trough with
no harmonics. Creates vibrato and chorusing effects when used to modu-
late Delay Time.
TRIANGLE: A periodic wave creates a triangle shape in moving from peak
to trough. Creates similar effects to a sine wave when modulating Delay
Time, but with a sharper transitions.
SQUARE: A wave that alternates almost instantaneously between two
states. Creates octave and other pitch shifting effects when used to modu-
late Delay Time.
Sawtooth: A wave that very quickly reaches a peak and then ramps down
more slowly. When used to modulate Delay Time creates pitch shifting ef-
fects that change tempo.
RAMP: A type of sawtooth wave that ramps up slowly to a peak then drops
down quickly. When used to modulate Delay Time creates pitch shifting
effects that change tempo.
