2.29.15 Assigning Modulations to the [MOD ON/OFF] Key (MOD-KEY)
The modulations can be switched on/off in the individual modulation menus and parallely by means of
the [MOD ON/OFF] key.
For which modulations the [MOD ON/OFF] key is effective can be defined in the UTILITIES-MOD KEY
menu. The key can either be effective for all modulations or for a selected one.
Function of the [MOD ON/OFF] key if effective for a type of modulation:
Ø Every pressing a key alters the state (ON or OFF) of the selected modulation.
Function of the [MOD ON/OFF] key if effective for all types of modulation (ALL):
Ø If at least one modulation is switched on, pressing the [MOD ON/OFF] key switches the modulation/s
off. Which modulations were switched on is stored.
If no modulation is switched on, pressing the [MOD ON/OFF] key switches on the modulations which
were last switched off using the [MOD ON/OFF] key.
On switching on using the [MOD ON/OFF] key, the modulation sources are used as defined in the
modulation menus.
Access to the selection of the modulation to be switched using the [MOD ON/OFF] key is possible in the
UTILITIES-MOD KEY menu.
