I researched Fantasound as well and I’m recreating the Fantasound sountrack by using two sources, the 1957 stereo LP soundtrack and the mono soundtrack. For the choir and soloist parts i also used the linear track (which also has the mono mix) on my PAL VHS of Fantasia.
Thanks for inspiring you for me to recreate the theatrical 1940 Fantasound soundtrack myself😊😉😊😉
That would be truly incredible!
