I will look your suggestions. Very thanks!

Hummm... directly soundcard hardware??!!! :(

I will test your suggestions, but... I just wanna one program can show one image when pupil play one C note ,or G, etc and maybe control intensity of color with gain of sound. Something that it can select colors, pictures and texts using pure notes played with guitar or harmonic or other instrument. Is not to produce images but to *select* images or colors (images too) or text.

Is it programming direclty in soundcard hardware? Not exist some librariy done can make this job (send to my program one pure value represent the note played)? I don't want Midi sound, it is very horrible to hear :)

I know, I want much. But to our project is very interesting give for pupil the possibily to choose the relation note/color/picture or note/word.

Is it very hard? For me all in this audio-world is hard because I don't have much notion about hardware programming (I'm just one database specialist), but if it's possible just using done values sent of the one library, all is ok.

:) You will hear my screams!!

So... very very very thanks for your atention.
