First of all, are there any unison plugins out there? Unison is an effect where you have the original signal and the sound is made fatter by adding many copies of that sound being detuned (slightly pitched up or down) around the original frequency. It's different from chorus as it uses pitch shifting and not modulated delay I believe. That way unison gives a more "clean" fatter sound without any wobbling that you have with a classic chorus effect.
Normally you can determine the amount of voices being added (more = more CPU load, am I right?), where up to 7 or 9 (or more?) would be cool + determine how much the voices should be detuned, which is called stereo spread I believe.
Are there any plugins like that?!
Also, I have been told that in studio's they layer multiple takes in order to get the voice fatter. Can you also achieve this with a "voice fattener" plugin. Which do you recommend?!
Thanks!
