Type
-
Bypass
The filter is bypassed and the sound passes through un
affected.
-
6dB LowPass
Low frequencies pass through this filter and frequencies above the
Cutoff frequency
are reduced by 6dB per
octave.
For example: a frequency 2000Hz is 6dB softer in volume if the
Cutoff frequency
is set to 1000Hz.
-
6dB HighPass
Hi
gh frequencies pass through this filter and those below the
Cutoff frequency
are reduced by 6dB per
octave.
The filter is open if the
Cutoff frequency
knob is fully turned left.
-
12dB LowPass
Low frequencies pass through this filter and those above the Cu
toff frequency are reduced by 12dB per
octave.
-
12dB HighPass
High frequencies pass through this filter and those below the
Cutoff frequency
are reduced by 12dB per
octave.
The filter is fully open if the
Cutoff frequency
knob is fully turned left.
-
24
dB LowPass
Low frequencies pass through this filter and those above the Cutoff frequency
are reduced by 24dB per
octave.
-
24dB HighPass
High frequencies pass through this filter and those below the
Cutoff frequency
are reduced by 24dB per
octave.
The fil
ter is fully open if the
Cutoff frequency
knob is fully turned left.
Split 1
In this mode, Filter 1 and Filter 2 are in parallel, so that Filter 2 has the same properties, such as envelope,
filter tracking etc, as Filter 1.
The only difference is that F
ilter 2's frequency can be altered independently from Filter 1's.
Using Filter Pan in the advance screen, you can pan Filter 1 and Filter 2, from both being centered, to Filter 1
being panned left and Filter 2 being panned right.
Split 2
In this mode,
Oscillator 1 goes into Filter 1, Oscillator 2 goes into Filter 2 and Oscillator 3 goes into both Filter
1 and 2. Filter 1 and Filter 2 are also in parallel and joined, so that Filter 2 has the same properties, such as
envelope, filter tracking etc, as Filt
er 1. The only difference is that Filter 2's frequency can be altered
independently from Filter 1's.
Using Filter Pan in the Advance screen, you can pan Filter 1 and Filter 2, from both being centered, to Filter
1 being panned left and Filter 2 being pann
ed right.
Filter Envelope
The Filter Envelope is addressed to the main filter
Cutoff Frequency
of Predator and the amount is controlled
by the
Env
amount in the Filter section.
An envelope is a time based modulation inside a synthesizer. If you pres
s a key it moves from 0% up to
100% and back to 0% when you release the key.
Between this you can adjust the time how it does do this.
The first part is know as the attack, this is the time it takes to reach 100%.
