13. Module reference: LFO group
R
ST INPUT
An input signal which goes from 0 units or below to anything above 0 units will force the LFO
to restart its waveform cycle.
S
NC OUTPUT
The Snc (Sync) output sends out a high logic signal every time a new waveform period starts. This
signal can be used to restart other LFOs on their Rst input (see above) in order to sync the rates and
phase lock the signals.

ONO
Mono mode synchronizes the LFO modules in polyphonic patches to each other. This means
that if you play a chord, the module will control all voices in sync. The preset setting of this
parameter is Poly. Note that if you use the Clk (clock sync) rate mode (LfoB and LfoShpA), Mono mode
will synchronise the frequency and the phase of the LFOs, whereas Poly mode will only sync the
frequency of the LFOs.
KBT
SCROLL BUTTON
KBT, KeyBoard Tracking, is the hard-wired connection between the LFO rate/pitch and the
keyboard (and the MIDI input). Click to select Off, 25%, 50%, 75% or 100%. If KBT is set
to 100%, the LFO will track the keyboard at the rate of one semitone for each key. If KBT is set to Off,
the keyboard will not affect the LFO rate. Note that if you use the Clk (clock sync) rate mode (LfoB and
LfoShpA), the KBT setting will have no effect.

YPE SCROLL BUTTON
With the Output Type scroll button you determine how the LFO signal should be output. There
are six different alternatives:
• B
: Bipolar signal ranging from -64 to +64 units, peak to peak.
IP
• B
I
: Bipolar signal ranging from -64 to +64 units, peak to peak
IP
NV
but 180 degrees phase shifted compared to the 'Bip' alternative
above.
• P
: Positive Unipolar signal ranging from 0 to +64 units, peak to
OS
peak.
• P

to peak but 180 degrees phase shifted compared to the 'Pos' alterna-
tive above.
• N
: Negative Unipolar signal ranging from 0 to -64 units, peak to
EG
peak.
