ALLIGATOR TRIPLE FILTERED GATE
912
Filters and Modulation
The three channels have identical settings, even though their filters are of different types. Below, all descriptions ap-
ply to all three channels, if not explicitly stated.
Filter On button
When this is on, the channel’s signal passes through the filter. Turning this off bypasses the filter. Note though that
the Gate, Amp Envelope, effects and other settings are still active.
LFO Amount
Determines how the filter frequency should be affected by the global LFO (see below). This is a bipolar control, allow-
ing for positive or negative modulation of the filter frequency.
Frequency
q For a general introduction to different filter types, see “The Filter Section” in the Subtractor chapter.
• For the high pass filter, this is the cutoff frequency.
Frequencies below this will be removed from the signal. Turning this parameter up will gradually remove more and
more of the signal, leaving only the highest frequencies.
• For the band pass filter, this is the center frequency.
Lower and higher frequencies will be removed from the signal.
• For the low pass filter, this is the cutoff frequency.
Frequencies above this will be removed from the signal. Turning this parameter down will gradually remove more
and more of the signal, leaving only the lowest bass frequencies.
Resonance
The filter resonance emphasizes the frequencies around the set filter frequency. Turning this up will make the filter
sound more pronounced and ringing.
Envelope Amount
This determines how the filter frequency is affected by the Filter Envelope (see below). This is a bipolar control, al-
lowing for positive or negative modulation of the filter frequency.
