The Low Frequency Oscillator (LFO) generates a signal which can be used to modulate the
frequency cutoff point.
RATE sets the basic speed (tempo) of oscillation.
MULTIPLIER sets the multiplication of the basic tempo – e.g. If the x1 setting corresponds to
quarter note tempo, then x0.5 creates half note tempo, x1.5 quarter triplets, x2 eight notes, x3 eight
triplets and x4 sixteenth notes.
SHAPE selects the waveform – square wave, ramp down, triangle, ramp up or random levels.
The TAP switch can be used to rhythmically tap the tempo and to restart the LFO cycle.
The time between two taps will set the basic speed of the oscillator (maximum 1.2 sec between taps
– for very low speeds the rate control must be used). Tapping only once will reset the start of the
LFO.
When the SYNC switch is pressed, the LFO will synchronise to incoming MIDI clock messages on
the MIDI input. If no MIDI clock data is detected, the sync switch LED will flash. From the
moment MIDI clock is received, the LFO will synchronize and the LED will stay on. Pressing the
SYNC switch again will turn off MIDI sync. Receiving a 'start' MIDI message will reset the start of
the LFO cycle.
Envelope-LFO Link Switches
The envelope signal can be used to modulate various parameters of the LFO.
When the ENV-LFO switch is set, the envelope controls the output level of the LFO.
The LFO knob still controls the overall level to modulate the frequency cutoff.
When the ENV-RATE switch is set, the envelope controls the basic speed of the LFO.
When the ENV-MULTI switch is set, the envelope controls the multiplier value of the LFO.
