Delay: When a time-delayed signal is superimposed with the original signal it leads to interference's of the overtones due to the different phase-shifts of the overtones. The resulting color play is especially impressive, when the time-delay is modulated with an LFO.

A choir-effect arises when several voices try to sing the same song. In practice they will a little differ in the pitch and the timing resulting in a nice humming sound. Also instruments that are not exactly tuned leads to this choir effect like a string orchestra or a brass section. For an artificial choir-effect you can produce multiple voices by changing the pitch and the delay of multiple copies of the original and mix them together.

A phaser shifts the phase of an audio-stream and mix it together with the original signal. The result are interference's that changes the sound color. The amount of phase shift can by modulated with an ADSR- or LFO-generator.

Distortion: When a signal is strongly amplified it will be clipped at the limits of the amplifier resulting in square-pulse like waves with a very acid sound.

A resonator adds a positive feedback to a signal so that it will build up the resonant frequencies that are characteristic to the geometry of the resonator. Many natural instruments has a resonant body that make up their specific sound like a violin, guitar or trumpet.

The detune effect mixes two or several detuned copies of a signal to produce a humming sound. For an example: the hammer of each note of a piano excites 3 slightly detuned strings to produce the characteristic piano sound. If they are strongly detuned the result will sound like a honky tonk piano.
