This one contains vowels a,e,i,o,u from a female and male German speaker frequency tables.
cc1 (Mod Wheel) crossfades between vowels.
It is comprised of a choir of 8 singers where each has a different vibrato rate and timbre variation.
This is a proof of concept towards the development of a choir like synth. (also made for fun) I was trying to achieve Isao Tomita’s choral voice until I just found he used a Mellotron with actual choir tapes. lol
