SUBTRACTOR SYNTHESIZER
(RECORD+REASON)
543
Filter 2
A very useful and unusual feature of the Subtractor Synthesizer is the presence of an additional 12dB/Oct lowpass
filter. Using two filters together can produce many interesting filter characteristics, that would be impossible to create
using a single filter, for example formant effects.
The parameters are identical to Filter 1, except in that the filter type is fixed, and it does not have filter keyboard
tracking.
D To activate Filter 2, click the button at the top of the Filter 2 section.
Filter 1 and Filter 2 are connected in series. This means that the output of Filter 1 is routed to Filter 2, but both fil-
ters function independently. For example, if Filter 1 was filtering out most of the frequencies, this would leave Filter
2 very little to “work with”. Similarly, if Filter 2 had a filter frequency setting of “0”, all frequencies would be filtered
out regardless of the settings of Filter 1.
q Try the “Singing Synth” patch (in the Monosynth category of the Factory Sound Bank) for an example of how
dual filters can be used.
Filter Link
When Link (and Filter 2) is activated, the Filter 1 frequency controls the frequency offset of Filter 2. That is, if you
have set different filter frequency values for Filter 1 and 2, changing the Filter 1 frequency will also change the fre-
quency for Filter 2, but keeping the relative offset.
q Try the “Fozzy Fonk” patch (in the Polysynth category of the Factory Sound Bank) for an example how linked
filters can be used.
! Caution! If no filter modulation is used, and the filters are linked, pulling down the frequency of Filter 2 to zero
will cause both filters to be set to the same frequency. If combined with high Res settings, this can produce
very loud volume levels that cause distortion!
