EFFECTS MENU 665
Both of the individual filters of the connections mentioned above have the ability to
overmodulate themselves internally. With the "Drive“ dial, you can regulate the amount of
overmodulation. The more you turn this dial up, the more the signal is overmodulated. In
this case, the parameters of the internal workings of the filter interact with one another.
Increasing drive weakens the resonance, but, at the same time, the signal gets more
volume, more bass and becomes acoustically fuller.
Note: The two smaller dials from this section are explained under "Modulation".
"Modulation" section
You can automate your effects via the settings in the modulation section.
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.
Waveforms of the modulation section
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).
