Mute
SYSTEM MUTE turns off all outputs and lights both SYSTEM and EFFECT
MUTE LEDs. Pushing EFFECT MUTE while in system- mute mode turns
the effects alone back on.
Pressing SYSTEM MUTE, then EFFECT MUTE, allows you to hear only the
effect channels of the CP-1. This is particularly useful for making fine
adjustments of parameters.
EFFECT MUTE alternately turns off and on all signals added by the CP-1.
Use it to compare the sound with and without CP-1 processing. In TEST
mode EFFECT MUTE clears all user memories. (See page 21.)
