===== MIDIBox Fx Option =====
The MIDIBox **Fx Option** (special sound effects option) is needed for more complex sound creation. 
With the MIDIBox AY **Fx Option** it is possible to do timed sound modifications. 

=== Concept: ===
You can enable the **Fx Option** via the **MIXER MENU** [Press Key F3] [toggle **Fx Option** on/off via key A,B,C]. If the **Fx Option** is activated - just **adjust Fx Functions** at the **Fx Menu** [Press F8] ...	


=== Fx Menu: ===

  * [Fx Function]	=> See **Fx Functions list** below
  * [Fx Pos     ]	=> Fx Position (the Fx chart allow 32 (POS 0-31) entries)
  * [Fx Time    ]	=> Adjust the **Fx execution timer**: Wait 0-100 timer cycles **befor** the current Fx execution.
  * [Fx Data    ]	=> Optional **Fx Function Data** (See Fx Functions list below)


=== Fx execution workflow:  ===

(*)

Every time when a **Note On** event occur the 
**MIDI Note** will be written to => MIDI Note On #1.
MIDI Note On #1 will be written to MIDI Note On #2, 
MIDI Note On #2 will be written to MIDI Note On #3
This will enable a sorta "**Chord Arpeggios**" [via Fx Option]
