4. Vocoder parameters
Front panel vocoder parameters
[VOCODER] button
This switches the Vocoder function on/off.
Off (LED unlit): Vocoder is off. The program will not use the vocoder.
On (LED lit): The vocoder is on. The program will be a vocoder program,
and the vocoder parameters will be available for editing.
If you turn the [KNOB FUNCTION SELECT] dial to FULL EDIT, you'll be
able to edit the vocoder parameters (VC CARRI–VC BAND pages).
VC CARRI (Vocoder Carrier)
On this page you can set the input level of the audio signal being used as
the carrier
TMBR1.LVL (Timbre1 Level).................................................... [000...127]
Specifies the output level of Timbre1 (carrier).
INPUT2.LVL (Timbre2 Level) ................................................... [000...127]
Specifies the output level of Timbre2.
VC MOD (Vocoder Modulator)
In this page you can adjust settings for the modulator, which applies its
character to the carrier audio.
For the modulator, you can use an external audio source such as a mic or
rhythm (AUDIO IN) or timbre 2.
SOURCE (Audio Source) ................................................ [INPUT, TIMBRE2]
This selects the audio source that will be sent to the modulator.
INPUT: The audio source of AUDIO IN will be sent to the modulator.
When the AUDIO IN [XLR/LINE] is set to LINE, the source from the rear
panel AUDIO IN [LINE] jack will be sent to the modulator.
When the AUDIO IN [XLR/LINE] is set to XLR, the sound from the mic con-
nected to the front panel AUDIO IN [MIC] (XLR type) jack will be sent to the
modulator. This is the typical "vocoder using a mic" setup.
TIMBRE2: The output of timbre 2 will be input to the modulator.
GATE.SENS (Gate Sensitivity) ..................................................[000...127]
Specifies the speed at which the gate will operate according to the
"THRESHLD" setting.
Lower values for this setting will make the gate close more quickly, causing
the vocoder sound to decay more quickly.
Higher values for this setting will make the gate close more gradually, caus-
ing the vocoder sound to have a longer decay.
If the "THRESHLD" value is high, this effect will apply more readily. If the
NOTE
threshold value is 0, there will be no effect.
THRESHLD (Threshold) ...........................................................[000...127]
Sets the level at which the input source will be cut. By setting this to an
appropriate level, you can cut the noise that might be present during times
where there is no input. Higher settings will make it more likely that the
input source will be cut.
With excessively high settings, it's more likely that the audio input
signal itself will be cut, making it difficult for you to apply the vocoder
effect as intended.
HPF GATE ...................................................................[DISABLE, ENABLE]
The microKORG XL's vocoder can extract the high-frequency portion from
the audio source being input to the modulator, and then mix this into the
output of the vocoder. You can specify whether this high-frequency portion
will be mixed in only while the internal sound generator (Timbre1) is produc-
ing sound, or at all times.
DISABLE: The high-frequency portion will be mixed whenever the audio
source is being input to the modulator.
ENABLE: The high-frequency portion of the audio source will be mixed
only when the internal sound generator (Timbre1) is producing sound.
HPF LVL (HPF Level) ...............................................................[000...127]
This adjusts the output level from the HPF (High Pass Filter) that extracts
the high-frequency components from the modulator input source; these
high-frequency components are then mixed into the output of the vocoder.
Increase this value if you want to emphasize the consonants of the vocal
input source.
