LFO Section
The 2-pole Filter is equipped with a low frequency oscilla-
tor (LFO) that can be used for cutoff modulation purposes.
The LFO generates a periodic triangle waveform with
adjustable frequency and depth.
Depth
This knob controls the modulation
depth. The basic principle: the higher
the value, the more intensive the LFO
modulation. If you do not want to use a
LFO filter modulation, turn Depth into
the leftmost setting.
Speed
Speed sets the frequency of the LFO
depending on the position of the Range
selector.
At low settings, it might take some time
for the LFO to perform a complete cycle
while higher settings are up to the audible range.

By the way: The LED above the Speed knob is
pulsating rhythmically to the LFO frequency.
Range
This selector controls the basic speed of
the LFO:
• Fast uses a very fast LFO speed range
that goes up to audio level. This adds a
tonal element to your processed audio
signal.
• Slow uses a slow LFO speed for periodic filter
movements.
• Gemütlich ("comfortable") uses a very relaxed
LFO speed for slow modulations. It is perfectly
suited for modulating pads and strings.
