// 
// A three-note chord generation module.  Three note values are output, which
// would typically be wired to the inputs of oscillators.  There are 32 Chords 
// available, which are defined in Chords.cpp.
//
// Example usage:
//
//    ModuleWavetableOsc *wavetable_osc1 = new ModuleWavetableOsc();
//    ModuleWavetableOsc *wavetable_osc2 = new ModuleWavetableOsc();
//    ModuleWavetableOsc *wavetable_osc3 = new ModuleWavetableOsc();
//
//    ModuleQuantizer *quantizer = new ModuleQuantizer();
//    ModuleExtClock *ext_clock = new ModuleExtClock(120, EIGHTH_NOTE_CLOCK_DIVISION);
//    ModuleChords *chords = new ModuleChords();
//    ModuleMixer3 *mixer_3 = new ModuleMixer3();
//
//    quantizer->cv_input = inputs->sr;
//    quantizer->scale_input = inputs->param1;
//
//    chords->root_note_input = quantizer;
//    chords->chord_input = inputs->mod;
//
//    wavetable_osc1->wavetable_input  = new ModuleConstant(0);
//    wavetable_osc1->frequency_input  = chords->note_1_output;
//
//    wavetable_osc2->wavetable_input = inputs->param2;
//    wavetable_osc2->frequency_input  = chords->note_2_output;
//
//    wavetable_osc3->wavetable_input = inputs->param3;
//    wavetable_osc3->frequency_input  = chords->note_3_output;
//
//    mixer_3->input_1 = wavetable_osc1;
//    mixer_3->input_2 = wavetable_osc2;
//    mixer_3->input_3 = wavetable_osc3;
//
//    this->last_module = mixer_3;
