FREQUENCY
In this example, you can see that low frequency components are removed whilst high
frequencies pass through. This filter can be used to make sounds very thin and brittle. For
example, this type of filter may be used effectively on an oboe sound or harpsichord sound.
When the resonance is increased, the area around the cutoff frequency is boosted and so
harmonics around that frequency will be emphasised.
The final mode selection is quite unlike those shown above. Selecting EQ turns the second
filter bank into a simple one band equaliser with variable frequency and resonant cut/boost that
can be used for a variety of different effects. With the EQ selection, the ‘straight’ sound from
Filter 1 is also passed through unaffected and you can use this EQ section to highlight specific
frequencies in the sound. This filter is also able to be controlled by any of the modulation
sources we have seen so far and using it with a high resonance setting in conjunction with any
of these modulation sources, you may create interesting sounds not unlike phase shifting.
The response slope for the EQ selection is shown below:

With resonance at 16, the frequency response is flat but as the resonance is increased, the
gain of the filter is boosted around that frequency. If the resonance is decreased, the gain is
cut as the resonance gets sharper.
The fields on the FILTER 2 page are as follows:
The parameters across the top of the page follow the usual convention and allow you to select
the keygroup for editing, select whether you wish to edit just one keygroup or all keygroups
simultaneously and, of course, you can select another program for editing if you wish.
