Daft Synth - Korg DS-10 + formant synthesis

A few days ago i was blown away by this video…

until today.

Not knowing anything about formant synthesis that is.

Flemming pointed out in the chat, that you need a lot more band pass filters to achieve some vowels,

and now that i watch the video again it seems that theres no modulation going on for some words!

So is this video 100% definitely fake?

Such a shame if it is!
