Effect name: Flip-flip Octaviser

Effect description: 
Uses the FLIP FLOP OCTAVE model in the destructor to emulate a flip flop circuit to
generate tones at the frequency you're playing at or octaves below.  This is basically
how the original Boss OC-2 pedals worked.  


Left pot label: Octave
Left pot function: Sets the frequency of the flip-flop.  Full left is same as note you're playing
                   and full right is 2 octaves down.

Center pot label: Tone
Center pot function: Sets tone of the low-pass filter following the desctuctor

Right pot label: Clean mix
Right pot function: Sets the amount of clean signal mixed in.

Left footswitch label: Bypass
Left footswitch function: Bypasses the effect

Right footswitch label: Not used
Right footswitch function: Nothing
