Yamaha Clavinova CLP-152S Owner's Manual page 18

Normally the Clavinova will respond to MIDI control change data received from an external MIDI device or
keyboard, causing the selected Clavinova voice to be affected by pedal and other "control" settings received
from the controlling device. The Clavinova also transmits MIDI control change information when one of its
pedals are operated.
This function makes it possible to cancel control change data reception and transmission if you do not want
the Clavinova voices to be affected by control change data received from an external device or vice versa.
