On the rising edge of <SaveFilterPreset>, the current filter values for all 48 filters
will be stored in the preset specified by <FilterPreset#> Valid values for
<FilterPreset#> range from 1 to 5.
A rising edge of <RecallFilterPreset> will recall the type, gain, frequency and Q of
the specified <FilterPreset#> for all 48 filters.
The outputs <FilterType_F> through <FilterGain_F> report the current filter
settings.
