Chapter 6 Filter 107
The parameters in this section control the overall output of the EVOC 20 Filterbank.
 Overdrive button: Turns the overdrive circuit on or off.
Note: To hear the Overdrive effect, you may need to boost the level of one or both
filter banks.
 Level slider: Sets the level of the output signal.
Stereo Mode pop-up menu: Sets the input/output mode of the EVOC 20 Filterbank.
The choices are m/s (mono input to stereo output), and s/s (stereo input to stereo
output).
Set Stereo Mode to m/s if the input signal is mono, and to s/s if the input signal is
stereo. In s/s mode, the left and right stereo channels are processed by separate filter
banks. When using m/s mode on a stereo input signal, the signal is first summed to
mono before it is passed to the filter banks.
 Stereo Width knob: Controls how the output signals of the filter bands are distributed
in the stereo field.
 At the left position, the output of all bands are centered.
 At the centered position, the output of all bands ascends from left to right.
Â
At the right position, the bands are output evenly on the left and the right channel
.
The stereo/stereo mode (s/s) uses one A/B filter bank per channel. The positioning of
the frequency bands correspond to that described above, but the bands of each filter
bank ascend in opposing directions, from left to right.
EVOC 20 TrackOscillator
The EVOC 20 TrackOscillator is a vocoder with a monophonic pitch tracking oscillator.
The tracking oscillator allows the EVOC 20 TrackOscillator to track (follow) the pitch of a
mono input signal. For example, if the input signal is a vocal melody, the individual
pitches of the sung notes will be tracked and mirrored by the synthesis engine.
The EVOC 20 TrackOscillator features two formant filter banks, an analysis and a
synthesis filter bank. Each has several (configurable) input parameters. You can use the
track into which the EVOC is inserted as the analysis signal source, or use another audio
track as the input source via a Side Chain. The synthesis source can be the track into
which the EVOC is inserted, another audio track, or the tracking oscillator. Each analysis
frequency band has an envelope follower that tracks the level of that band, so that it
can be remodeled more precisely.
The signal path of the EVOC 20 TrackOscillator is shown in the block diagram on
page 224.
