Section 6: Detailed Parameter Descriptions
Frequency Fade Amount / Rate
Frequency fading emulates the phase anomalies
introduced in radios due to reception quality. Best used
when emulating any device that communicates without
wires.
TRANSDUCER | Distortion
The Distortion Block in Transducer is simple to use. Pick a
style and set the amount of distortion. 0 will result in no
distortion effect. The styles are created with the amount set
at "unity". The benefit of the block comes from the
complexity of the styles. The distortion algorithm can
reproduce non-standard curves to reproduce anything from
solid-state distortion to a torn speaker.
TRANSDUCER | Noise
A real-world transducer can have a complex noise pattern
generated by the means of communication or by the device
itself. The TRANSDUCER / Noise Block allows various
noise patterns to be created.
Overall Noise Level
This parameter is on the output of the Noise Block.
Therefore, hiss, pink, buzz, or hum level must be on before
any output is heard.
Hiss Level / Freq
Hiss is the noise pattern often associated with tape
playback. The sound can also be heard in radio
transmissions. In general, a higher hiss frequency would
represent a higher quality transducer device.
Pink Level / High Cut / Low Cut
Pink noise is broadband noise. By adjusting the High and
Low Cut, the noise can be shaped to match the band
shape characteristics of a transducer device.
Buzz Level
Buzz is the noise pattern often associated with a guitar
amplifier.
Hum Level / Power Freq.
A hum noise pattern is typically a result of grounding
problems in an audio path. The frequency of hum is
affected by main voltage. Therefore, 60 Hz emulates the
hum sound for North America and Japan, 50 Hz represents
most other countries.
MATRIX | Blocks
The MATRIX / Block Tab allows quick access for the
enabling and disabling of blocks in VoicePro.
Use the Up and Down Arrow Buttons to highlight one of the
five lines. The four soft knobs enable/disable the blocks on
the highlighted line. For convenience, you can
enable/disable any block directly on the block's edit tab
using the OK Button.
The Harmony Compressor, De-ess and EQ blocks are only
available when Harmony is engaged.
