Musical keyboard? help please

hello brothers, i am a very fustrated.
I´m trying to make in flash a musical keyboard, but by that treatment is not
:frowning: is very bad.
I wanted to ask to them please a little in this can help me.

Most important of this it is that when maintaining pressed the letter of the keyboard, “blim” of the sound is listened to, and that is observed in the screen frame pressed, and if it stays tight the key follows in that frame.

That is most problematic than I have.

thanks and excuses by the annoyances
sorry for my English.
