LFO 2 (Low Frequency Oscillator 2)
The second LFO generates six waveforms and can be used to modulate
the frequency of the oscillators to produce a vibrato effect, to modulate
the low-pass filter’s cutoff frequency for periodic harmonic changes, or to
modulate the VCA level to create tremolo style effects.
LFO 2 can be triggered by pushing the bender upwards or by applying
aftertouch. In addition, it can be switched on permanently. The type and
amount of modulation controlled by LFO 2 is determined by the faders
DDS

VCF
and
VCA

WAVEFORM: This rotary switch allows you to choose from six different
waveforms: sine, reverse sawtooth, sample & hold, square, sawtooth or
sample & glide.
Polarity
of output values
LFO 2 waveforms.
• Sine can be used to produce vibrato effects as it alternates equally
between positive and negative values. This is a bipolar waveform.
• Reverse sawtooth
,
square
and
sawtooth
generate positive values
that allow for pulsating sounds or modulations. The square wave can
also be used to create trill-like effects at higher rates.
• Sample & hold
produces random positive or negative values for the
duration of one duty cycle.
Sample & glide
also generates random
values, but glides from one value to the next. Both waveforms can be
used to create either subtle movements or wild effects. With RATE
set
to its highest value, both waveforms will generate a white noise signal.
