Sound generator section
Sound generation on the ARX-02 involves four stages: Tone (Type,
Pickup/Bell), MFX, Pre Amp, and Speaker.
The Tone stage specifies mainly the settings of the electric piano itself,
such as differences due to the type or model of the electric piano, and
the way in which the condition of the instrument affects the sound.
The MFX stage lets you apply various effects.
The Pre Amp stage lets you make pre-amp settings. Since it is
independent of the Tone stage, you can also create combinations that
do not exist in reality.
The Speaker stage let you make speaker settings.
Patches
The sound generator settings can be saved as "patches."
The ARX-02 Electric Piano contains fifty patches.
If the ARX-02 is installed in a Fantom-G, this patch data is saved in
the Fantom-G Project.
