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
