LFO (Low Frequency Oscillator)
The LFO (Low Frequency Oscillator) is an oscillator that produces a rela-
tively slow (low-frequency) oscillation, and is used to apply cyclic modula-
tion to various aspects of the sound. Some typical ways to use LFO are
vibrato (use LFO to raise and lower the pitch), wah (use LFO to raise and
lower the cutoff frequency), and tremolo (use LFO to raise and lower the
volume). You can select LFO as a Virtual Patch source, select the desired
parameter as the destination, and apply modulation to produce various
effects. The microKORG XL+ provides special parameters that can be
modulated from an LFO. If the OSC1 page "OSC MOD" parameter is set to
WAVEFORM, the LFO1 will be able to modulate the "C2.LFO1.MD" param-
eter, and the LFO2 will be able to modulate the PITCH page "VIB INT"
parameter.
WAVE (LFO1) ............................. [SAW, SQUARE, TRIANGLE, S&H, RANDOM]
WAVE (LFO2) ..................................[SAW, SQUARE+, SINE, S&H, RANDOM]
Selects the LFO waveform.

KEY SYNC ................................................................[OFF, TIMBRE, VOICE]
Specifies how the LFO will be applied to a voice when note-on occurs.
OFF: The LFO phase will not be reset when note-on occurs.

(Sample & Hold)

TIMBRE: The phase of the LFO will be reset by the first note-on that occurs
from a condition of no keys being held; it will not be reset for subsequently
played voices.

Note all off
VOICE: The LFO phase will be reset at each note-on, and modulation of dif-
fering phases will apply to each voice.

1VOICE
2VOICE
BPM SYNC ................................................................................[OFF, ON]
Specifies whether the LFO cycle will be synchronized to the internal tempo
or to an external MIDI Clock.
OFF: The LFO will not be synchronized. It will operate at the frequency
specified by the "FREQ" parameter.
ON: The LFO will be synchronized to the [TEMPO] knob or to MIDI Clock
messages from an external device.
If "BPM SYNC" is On, selecting LFO1FREQ or LFO2FREQ as "DEST" in
NOTE
PATCH 1–6 will have no effect.
