Effect name: Polyphonic guitar synth pedal
Effect description:  This is a polyphonic guitar synth meaning that it tracks
multiple strings.  It uses an FM synth engine along with ADSR envelope generator
and an output filter.  The pedal is configured by default to use a triangle
(OSC_TRIANGLE) wave that is modulated with a sine wave (OSC_SINE).  However, lots
of interesting sounds can be created by swapping these out with out types of oscillators
(e.g. OSC_SQUARE, OSC_RAMP_POS, OSC_RAMP_NEG, OSC_RANDOM, etc).

Left pot label: FM mod depth
Left pot function: The depth of the FM mod in the synthesizer

Center pot label: Attack time
Center pot function: The attack time of the synth sound (i.e. how long it takes 
to ramp to full volume when you play a new string)

Right pot label: Modulation frequency
Right pot function: The frequency of the FM modulator ranging from 0.25 x the note played
to 4.25x.

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

Right footswitch label:
Right footswitch function: describe right footswitch function
