2.6.1.3 [MOD ON/OFF] Key
The modulations can directly be switched on/off using the key [MOD ON/OFF] or by accessing the
MODULATION menu. When switching on using the [MOD ON/OFF] key, the modulation sources which
are set in the modulation menus are used.
The [MOD ON/OFF] key can either be effective for all modulations or for a selected modulation. The
selection for which modulation the [MOD ON/OFF] key is effective is made in the UTILITIES-MOD KEY
menu (cf. Section " Assigning Modulation to [MOD ON/OFF] Key").
When selecting a certain type of modulation, each pressing the [MOD ON/OFF] key switches on or off
the modulation selected.
In the case of selection "all modulations", the [MOD ON/OFF] key has the following effect:
• At least one modulation is active:
Pressing the [MOD ON/OFF] key switches off all active modulations. Which modulations were active
is stored.
• No modulation is active:
Pressing the [MOD ON/OFF] key switches on the modulations which were last switched off using the
[MOD ON/OFF] key.
