The Mellotron Group

Hi All,

I pulled out ELP's Works I last night and noticed while listening to C'est la vie pretty extensive use of a "choir" sound/sample.  I'm just not sure if it's a Tron or not.  The primary keyboard on the album is the GX1, but I don't know if it's capable of that sound.  Anyone know what made that "choir" sound?

Regards,

John
