I'm trying to make a synth effect and am
A) Looking for advice on building the effect
B) Trying to figure out the goddamn name of it so I do some searches for material.
It's a sort of chorus-y like effect where when you hit a key on the synth multiple voices play the same note, but slightly out of tune giving it a bigger, fuller sound.
I'm not sure if there's an easy or a "right" way to do this, but I managed to do something close by just taking the midi-notes that were incoming to my synth patch and generating 4 new notes that were slightly off-pitch, so if the note played was 69, I'd send 68.9, 68.95, 69, 69.05, and 69.1 to get 5 voices spread over 20 cents.
This worked, but it didn't sound quite right, which makes me think there's something more to the actual effect.
Also, I just used + and - objects and had everything hardcoded, I'd rather have something where I could choose the number of voices and spread of de-tuning.
