Effect Guide
Analog, USB, and S/P DIF inputs
In Program, Combination, Sequencer, and Disk modes,
external audio sources from the analog, S/P DIF, and USB
inputs can be processed by insert effects, master effects, and
total effects just as they can in Sampling mode.
You can sample while applying the KRONOS's effects to the
external audio sources from these jacks, or use the KRONOS
as a 6-in (analog, S/P DIF, 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.
In each mode, use "Audio Input" (P0– Audio
Input/Sampling page) to make settings for the audio inputs.
Alternatively, you can check Use Global Settings and use
the Global mode "Audio" settings.

Set Bus Select to specify the bus to which the external audio
input will be sent. You can select L/R, IFX1–12, 1–4, 1/2–
3/4, or Off. If you want to apply an insert effect, select
IFX1–12.
Send1 (to MFX1) and Send2 (to MFX2) become effective
only when Bus Select is set to L/R or Off. If IFX1–12 is
selected, use P8: Insert Effect page Send1 and Send2 for the
post-IFX signal.
The diagram (Fig. 2–4a) shows an example in which the
input from INPUT 1 and 2 is panned to left and right, and
sent to insert effect 1.
In Disk mode, effects will use the settings of the mode in
which you previously were.
