where can i submit a question/idea about a product that doesn't exist yet to apple?

hi,

i'm an artist, and i've been for a long time interested in the developpement of a music composing tool based on vocal technology mixed with a tactile-eyesight environment that could allow anyone to easily compose music of their own by singing;

this process could include video ( editing ) too.

since i'm only an user, not a programmer neither a technician, i've had in mind for a long time to try and keep in touch with apple products developpers to evoke this concept and idea, but i didn't managed to find an email or didn't know who to contact about that.

can you please tell me where to write or who to join ?

regards.
