5.4.3.1 Frequency Modulation Settings
To open the "Frequency Modulation" menu, select "Modulation > Configure > Frequency
Modulation" or use the MENU key under "Modulation".
In the upper section of the menu, the modulation source is selected and the modulation
is switched on. The modulation source can be selected independently for the different
modulation types and the LF output.
The configuration of the selected external and/or internal modulation source is performed
in the lower section of the menu (internal source only).
These settings affect all modulations which use the same modulation sources.
