Here, you’ll find the so-called low frequency oscillator (LFO), which resonates
with adjustable speed. You can influence the speed and type of resonance.
To influence the resonance, use the two small dials in both the reduction and
filter areas. These four dials display modulation targets.
Example: You’ve left the dial for the sample rate at its default setting. Change
the small dial beneath from its middle position to either side. The modulation
for the dial value is added to the sample rate: The LFO now controls these
parameters proportionately and the sample rate reduction resonates at this
modulation.
You can use this technique on other dials as well. You just have to make sure
that the main dial isn’t turned up to full, because then the modulation wouldn’t
have any effect. The modulation is always added to the set value.
Example: Turn the small dial beneath the "bits" dial fully to the left (Value: -50)
and the one beside it (beneath "sample rate") to the right (+50). You’ve now
assigned a modulation to both parameters with the LFO. They are not changed
uniformly, but rather opposite to one another: A negative setting is nothing
more than an inversion of the modulation, so you’re effectively turning down
the control signal.

We’ve already explained this example with the help of sine oscillation. The LFO
can be in:
 Sine form
 Square wave (0 or 1, no intermediate level)
 Random value (an internal randomizer will be queried at the set speed)
Oscillator speed
The LFO speed is specified with the "speed“ dial. If the "sync“ button is active,
then the LFO adapts to the song speed, and the dial locks musical values into
place (e.g. ¼ note). Rhythmic paths of the sound distortion are therefore
enabled. You can also switch off this synchronization and set the speed
manually (in Hz).
Modulation with the "Envelope follower“
In the modulation section you’ll find a fourth button, the audio input signal. If
this mode is active, then the signal itself can be called upon to extract
