Live Adapt - DigiTech vocalist live fx Owner's Manual

Live Adapt™

The Live FX's Live Adapt feature uses the built-in microphone or Aux In jack
to listen to the music and automatically adjust noise gate threshold (built-in
microphone only), pitch effect key, harmony key, and delay and modulation tempo.
These options can be enabled and disabled independently in the Live Adapt menu
and then turned on and off globally with the Live Adapt button. Following is a
description of each of the options available in the Live Adapt menu.
GATE
This option has two settings:
• Preset
With this option selected, the gate threshold will not adapt and will be set
according to the "GATE" parameter setting in the Gold Channel Edit menu.
• Adapt
With this option selected, the audio analyzed by the built-in microphone is
used in combination with the vocal microphone signal to modify the gate
threshold from its baseline "GATE" parameter setting in the Gold Channel
Edit menu. When adaptive gate is enabled, the Live FX detects when the
dominant sound source is not close to the microphone, and more aggressively
gates the signal to reduce the amount of background noise leaking through
the vocal mic. As soon as the Live FX detects that someone is singing into
the vocal microphone, the gate is moved back to its baseline level to prevent
cutting out lower level vocal sounds.
One common problem with vocal processors occurs when a singer is playing
an acoustic guitar while using vocal effects, such as harmony or modulation.
When the singer stops singing but continues playing, the sound of the guitar
can leak through the vocal mic resulting in an unintended processed guitar
sound. Setting the gate high enough to prevent this can unfortunately result in
lower vocals being cut out. To help minimize this problem, try setting the gate
to the highest setting that still passes your vocal at low levels, and then enable
the adaptive gate. When you stop singing, the gate threshold will increase, but
it will return to your nominal setting as soon as you resume singing.
NOTE: The adaptive gate sensing algorithm relies on comparing the
vocal microphone signal with the built-in microphone inside the Live
FX case. When a connection is plugged into the Aux In jack, the built-in
microphone is disconnected. As a result, the adaptive gate is disabled
when using the Aux In jack.
PITCH
This option has two settings:
• Preset
With this option selected, the Pitch FX key will not adapt and will be set
according to the "KEY" parameter setting in the Pitch FX Edit menu.
• Adapt
With this option selected, the audio analyzed by the built-in microphone or
Aux In jack is used to favor notes that are present in the background music.
The Pitch FX KEY setting will still provide the baseline information for the
