INSTRUMENTS / GENERATORS
Sytrus - The Effects Module
effects module offers high-quality chorus effect, 3 delay lines which
can process either in parallel or in serial (with the possibility to
send the module output to a mixer
send track for further processing) and a reverb section.
Allows you to pan the signal before it is processed by the effects.
The chorus effect enables you to enrich the stereo panorama and depth even
for simple patches. It can also be used as a less CPU-intensive alternative
to the integrated unison mode (see the main module page), if you don't need
to use any of the advanced unison features, such as sub-level voices, custom
- Order (ORD) - Sets the number of "stacked" flangers
to be used for the effect. Using more flangers makes the effect smoother
and richer. Drag the screen down until the indicator disappears to disable
- Depth (DP) - Controls the "chorus
depth" (amplitude of pitch oscillation for each of the stacked flangers).
- Speed (SP) - Controls the flange speed (speed
of pitch oscillation).
- Delay (DL) - Variable amounts of delay can
be applied to each of the stacked flangers. Use this parameter to define
the overall amount of delay applied.
- Spread (SR) - Each flanger is assigned
a different speed, depth, etc. in a range defined by the basic properties
provided for the Chorus effect. Increase the SPRD value
to "smooth" the spreading of the stacked flangers across the parameter
- Chorus Stereo Cross (CR) - This parameter
applies a stereo cross mix between the left and right channel audio output
Chorus effect. Increase the parameter value to mix more of the left channel
sound in the right one and vice versa. The parameter has range of -128
values mix inverted sound in the opposite channel.
- Chorus Level (VL) - Determines the level
of the processed signal into the overall mix.
You can load several presets for the chorus effect by clicking the
Options button on the Sytrus interface ()
and pointing to the chorus submenu.
Send Track Settings
Here you can select a mixer
send track and send level if you want to send
the signal to a track for further processing.
Select the send track number from the LCD (NUM) and adjust the send level
Delay Line Settings
The effects module includes 3 separate delay lines (echo) which can process
either in parallel or in serial.
To see the settings for each delay line, select one via the D1/D2/D3 switches.
To enable the effect, turn on the Enabled LED.
- Delay Feedback (FB) - Sets the feedback volume.
Setting this to maximum will create feedback that never fades out, while
setting it to minimum
will result in no feedback.
- Delay Time (TM) - Sets the signal delay
time (and amount of time between echoes in the feedback).
- Delay Stereo Offset (SO) - Lets you set a
time offset for the left or right audio channel, thus creating richer
stereo panorama of the delay effect.
To delay the left channel, use a negative offset value. To delay
the right channel,
use a positive value.
- Delay Volume (VL) - Sets the delay line output.
Keep in mind this parameter has a range of -128 to 128 - to decrease the
delay volume, position the slide near the middle. Negative values produce
echoes with inverted signal (phase).
- Delay feedback Mode (NORMAL, INVERTED, P.PONG) - Sets the feedback stereo
mode. Normal preserves the original stereo, Inverted swaps the left and right
channels once, Ping Pong swaps the left and right channels for each successive
- Tempo Based (TEMPO) - Enable this switch to make the delay speed tempo
based rather than absolute in time.
- Serial Processing (SERIAL) - Enable this
switch to feed the next delay filter with the output of the current delay
(thus processing in serial as
opposed to independent parallel processing). Only the first two delay effects
have this option.
- Enabled (ENABLED) - Turn this switch on
to enable the current delay line.
The effects module includes a high quality reverb based on the Fruity Reeverb FX plugin.
- Color Selector - Color has five settings: Brighter (B+), Bright (B), Flat (F), Warm (W), Warmer (W+). The Color parameter is used for adjusting the decay time of the bass frequencies of the signal. This allows you to
change the overall perceived mood or 'sound' of the virtual room. A bright room has a low bass response, while warm rooms have a higher bass response. In a flat room, the response of the
bass is equal to the general frequency response.
- Low Cut (LC) - Adjusts the low cutoff frequency. Use this to remove low frequencies from the input signal before reverb is added.
For example, if you are adding reverb to, say a drum track, you might want to remove some of the 'rumble' from the bass drum by attenuating the
bass frequencies. Setting this parameter to the minimum value will bypass the Low Cut filter, displaying OFF in the value field.
- High Cut (HC) - Similar to the Low Cut, this adjusts the high cutoff frequency. Use this to remove high frequencies from the input
- Predelay (PD) -
Controls the delay time between the direct input signal and the first reverb
reflection. This should be set to modest values for small rooms, and
can be increased in relation to increases in room size. Predelay creates
echo effect that can both add atmosphere and muffle the signal, so use
- Room Size (RS) -
Use this to set the size of the virtual room where the reverb is created.
The Room Size should be adjusted according to the decay time. Small rooms
better with a short decay time, large rooms sound better with longer
- Diffusion (DF) -
Controls the density of the reflections bouncing off the walls of the virtual
room. A low diffusion setting makes the reflections sound more distinct,
like closely spaced echoes. A high diffusion setting creates reflections
so close they sound more like noise, where no echoes can be distinguished.
- Decay (DE) -
Controls the decay time of the reverb, the time it takes for the signal
to decay to -60dB (1/1000 of the maximum amplitude). Use low decay times
small rooms or boxes, and long decay times for large rooms, halls or
churches. You should also make sure that the Room Size parameter has an appropriate
- High Damping (HD) -
This parameter allows you to adjust damping of the high frequencies in
the reverb signal over time. Damping refers to the high frequencies being
and dying out. This causes the sound to become gradually muffled and
warm like it is being absorbed in the room. Setting this parameter to the
value will bypass the High Damping, displaying OFF in the value field.
- Wet Level (WL) -
Sets the relative reverb (wet) signal level.
The articulation section allows you to apply an envelope, LFO, map keys, velocity
or unison mode voices to a set of predefined properties. To see the full list
of envelopes/mapping in the articulation section and their meaning, please
check the envelope editor page.
The filter mode supports the following articulation targets (controlled parameters):
- Panning (PAN) - Sets the module panning (graph
bottom = left panning, graph top = right panning).
- Volume (VOL) - Sets the module volume (graph
bottom = no output, graph top = maximum output).
