The amplitude of the modulation signal is controlled with the mod1 gain knob on the filter panel. As
you turn this knob to the right you will start hearing the effects of the cutoff frequency variations.
This cutoff frequency increases with the amplitude of the modulation signal. The filter also has a
second modulation input which modulates the cutoff frequency. The resulting modulation signal is
the sum of the two signals modulated by their respective gain values.
Step 5: Adjusting default module parameter values
Description
You have probably noticed that when you switch to the Player, the different modules appear with
their panel controls adjusted to specific values. In this example we will change the default cutoff
frequency, the name of the Vlowpass2 filter, and the location of its control panel on the Player.
Keep in mind that you can apply the same procedure to all the modules appearing in the construc-
tion area.
Construction
• In the construction area, double click on the Vlowpass2 module. A dialog box appears with
certain fields that you can edit.
• Set the value of the cutoff frequency to 20000.
• Change the name of the module to “my filter”.
• Change the display row to Row2 in the display row combo box.
• Click OK to exit the edition window.
Playing
When you launch the Player, the filter module appears on the second row. Note that the cutoff frq
knob on the Vlowpass2 front panel is completely turned to the right, which means that the filter
is fully open. Note also that the name appearing at the top of the front panel has been changed to
