To boost the volume back up a bit we will use a ‘Gain’ module. One other thing you will notice is that the volume of the synthesizer has reduced, this is because we are now removing more of the frequency content and so it sounds quieter. Also if you set the Q to 0.1 you’ll notice that you start to get a ‘whistling’ sound, this is because when the Q setting is very low, the frequencies close to the cutoff point are being heavily emphasised and you can start to hear the cutoff frequency as a tone by itself.

Feel free to experiment with the Filter Mod Control settings to get a feel for the sound of the filter as it changes.

Play some notes and try changing the cutoff frequency, you should hear more emphasis being added to the sound as the cutoff changes, much like the common low pass filter found on most synths. Open the cutoff control panel and set the value to 2000. Set the value to 0.5 and connect the module to the Q input of the filter. We want to keep the Q above zero otherwise you might damage your ears (and speakers). The resonance control on the 106 operates the opposite way around, higher settings produce greater emphasis, so later on we will flip our Q setting to operate like this.įirst create a new variable, open its panel, set its name to ‘Q’ and then set the range from 0.1 -> 10. The Q setting of the filter can range from 0 -> 10, where a lower value creates a sharper emphasis on frequencies near to the cutoff value.

Now we need to add a control for the Q value.
#Bidule extended series
In this last part of this series we will look into replacing the current filter section with something a bit more interesting.
