tone_synth object
This method defines the amount of fade time for subsequently generated notes.
bool set_edge_fades(double start_time, double end_time)
Parameters:
start_time
The length of time that the note will fade in.
end_time
The length of time that the note will fade out.
Return value:
true on success, false on failure.
Remarks:
There should always be at least a slight fade in all the tones to avoid unwanted clicking.
The fades can be useful for changing the characteristics of a sound. For example, changing the fade in changes the attack of the note, while changing the fadeout alters the decay. A longer fade in will create a smooth note attack, while a short fade in creates a sharper sound. A longer fadeout is useful for simulating a guitar or piano, while a shorter fadeout simulates an organ, etc.
If either the fade in or fade out parameters exceed the length of the note, the fades will automatically readjust themselves to fit the note's length.
These parameters are set in milliseconds, no function to set them in beats is available at this time.
The default start time set by the engine is 8 milliseconds, and the default end time is 12 milliseconds.
Example:

    // Make a C major chord in the bass and a spread out C major chord as the melody, simulating a toy piano.

    tone_synth synth;

    void main()
    {
    synth.tempo=120;
    synth.set_edge_fades(1, 5000); //the length will automatically adjust.

    //chord
    synth.waveform_type=2;
    synth.note("C4", 4);
    synth.note("E4", 4);
    synth.note("G4", 4);

    //melody
    synth.waveform_type=3;
    synth.note("C5", 4);
    synth.rest(0.666);
    synth.note("E5", 4);
    synth.rest(0.666);
    synth.note("G5", 4);
    synth.rest(0.666);
    synth.note("C6", 4);
    synth.write_wave_file("synth.wav");
