I'm trying to get a better understanding of what Unison is, as it's not explained in a lot of detail in Syntorial. It's similar to doubling and detuning, but with more "voices". Are the additional "voices" additional oscillators? Instead of 2 oscillators, we are adding 4 oscillators when there are 2 voices involved, then 8 oscillators when there are 4 voices involved? When adding 4 or 8 oscillators, they are all the same cents apart? Is all this correct? I'd appreciate any help, thank you!
