To reduce tonality using the 2 Band EQ:
1 For band 1, choose the Shelving mode at a frequency of about 80 Hz, a high Q value,
and a negative Gain value.
2 For band 2, choose the Peak mode at a frequency of around 180 Hz, a medium Q value
and also a negative Gain value.
On the EQ graph, you can see how the frequencies around 80 Hz are boosted, while
the surrounding frequencies are reduced.
3 Vary the frequency of band 2 (easily recognizable in the blue part of the EQ graph) to
influence the extent of bass drum tonality.
A further method for reducing the tonality of a drum sound that is rich with overtones
is to use a lowpass filter. In the following example, you will control the cutoff frequency
of the filter with an envelope.
To reduce tonality using a lowpass filter:
1 Reload the Standard Tutorial sound, choose A#0 as the basic pitch in Oscillator 1 and
modulate it (as shown in the example page 397) using Env 1.
2 Increase the Saturation parameter value to enhance the overtones of the drum sound.
Note, that the output of Osc 1 is directed to the filter, as the filter bypass button (the
arrow between Osc 1 and the filter) is activated.
3 Make the settings shown in the following graphic to the Filter section:
 Filter type: LP 24
 Cutoff value: 0.10
 Mod Source for Cut: Env 3
 Mod Amount for Cut: 0.60
 Resonance: 0.30
