The Ensemble effect creates the illusion of many voices playing in unison. Much like a chorus, it creates this effect by playing delayed copies of the incoming sound. On top of this, it modulates the phases of each voice to create a silky smooth result without any metallic flanging. The delay times for each voice are also modulated in order to detune each voice slightly.

Voices - Number of voices to play simultaneously.
Detune - How quickly to modulate the delay for each voice, affecting how detuned the voices will be.
Spread - Pans voices left or right for a stereo effect.
Mix - The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
