the Crack Modulator resumes emission of a constant signal.
The Crack Modulator superimposes its effect on all other mixer signals (Oscillator 1 and
2, Ring Modulator).
Crack Speed
1Hz...5000Hz
Determines the frequency of the Crack Modulator.
Crack Length
1 Cycles... Cycles
Determines the number of modulations the Crack Modulator creates.

To program an authentic sounding handclap, set Crack Speed to 105 Hz and
Crack Length to 3 cycles.
Filter Section
Once the audio signal leaves the mixer, it is sent to the filters. The Attack
offers a multimode filter with different filter types.
In a subtractive synthesizer a filter is a component that have significant
influence on sound characteristics. But the Attack was designed to make
drum and percussion sounds, for which the filter is used merely for fine
tuning the sound. Yet you can also create bass and lead sounds which
definitely require a filter.
For now, we’ll explain the basic function of a filter, discussing the type
used most commonly in synthesizers: the low pass filter.
The low pass filter type dampens frequencies that lie above a specified
cutoff frequency. Frequencies below this threshold are barely affected.
The frequency below the cutoff point is called the pass band range, and
the frequencies above are called the stop band range. The Attack´s filter
dampens frequencies in the stop band with a certain slope. The slope is
12dB per octave. This means that the level of a frequency that lies an octave above the
cutoff point will be 12dB less than those frequencies of the signal that fall into the pass
band. The following picture shows the basic principle of a low pass filter:

The Attack´s filter also features a resonance parameter. Resonance in the context of a
low, band or high pass filter means that a narrow frequency band around the cutoff
