Korg kronos Operation Manual page 228

Using Effects
Use this when you want the audio input to an effect to be
controlled by another sound. There are two FX Control
buses, which gives you a great deal of freedom for
controlling effects freely.
8. REC Bus sends the audio input to a REC bus.
In the P0– Audio Input/Sampling page, you can choose a
REC bus as the Sampling Setup Source Bus so that the
signal sent to the REC bus can be sampled or recorded
(only in Sequencer mode).
Noise can enter the KRONOS via these buses; see
"Avoiding extraneous noise" on page 97.
If you want to save the edited settings in the KRONOS,
you must write them. Use the Global mode page menu
command Write Global Setting to do this.
9. If you want to use the Global mode Input settings in
the other modes, check the "Use Global Setting"
option.
If you want to make independent settings for programs,
combinations, and songs, uncheck this setting.
