Well, there is a lot going on, but I’ll try to explain everything as simple as possible.
Here is a picture of my huge Ableton Rack :
( Forgot to delete the overdrive lol)
The first thing is a simple Fm patch. This kind of sound could be done with any Synth. But I think sytrus does the best job because you have way more control over the sound. This is how it sounds: https://clyp.it/dw145sy5
The three EQ’s, the two Phasers and the Vocoder are the things that shape the vowel. They all look like this:
The three EQ’s are all moving and shape the basic vowel, while the Vocoder and the phaser are all still and make the vowel stronger.
You can see that there is a lowpass at the last EQ. I did that because that also made the vowel stronger(Cant really explain why, but it does). Of course I had to bring that High end back with a lot of compression.
A thing that I do with all of my sounds is putting a very, very short reverb at the start of the chain to make it sound more wet.
All the other stuff in the chain tbh is very unnecessary and doesnt change the sound at all
I hope that helped you
