Audio Input
You can also use the external audio inputs in PROGRAM,
COMBINATION, and SEQUENCER modes.
You can apply the insert effects, master effects, and total
effects to external audio sources and sample them, or use the
NAUTILUS as a 4-in (stereo analog, and USB) 6-out effect
processor. You can also use an external mic input to control a
vocoder effect (026: Vocoder) applied to internal sounds.
In SEQUENCER mode you can also use the effects when
recording external audio sources to audio tracks.
When effects are applied to the audio inputs, certain
effect types or parameter settings may cause oscillation to
occur. If this occurs, adjust the input level, output level,
or effect parameters. Please be aware of this particularly
when using an effect that has a high gain.
Use the Sampling page of each mode to make audio input
settings. Alternatively, you can check
Use Global Setting
and make these settings in the GLOBAL > Basic Setup–
Audio page. Normally you will leave Use Global Setting
checked. Uncheck this if you want programs and
combinations to use their own settings–for example, when
writing a program to use as a vocoder effect.
