mr. welove8051 thank u so much . i went through the document . i have just one doubt .
can we give input to the isd 1700 through a keyboard?
because im not using a microphone to give music input.
to be specific... in the document you gave. in the example no#2 . there is something called analog input. what that means?
my main aim is to generate melody by generating different frequencies by using different capacitors. after the melody is generated, i want isd 1700 to save it and play it back . is it possible?
is it possible to interface the circuit i have uploaded with the isd 1700 ? or is there any other way to do it?

hi tahmid
i saw the products. but they are not ready to share any circuit details with me.
i have uploaded an image in which i have constructed a melody cicuit which is working well. im able to create all the 7 basic tones and also hear it through the speaker .
now my major doubt is , is it POSSIBLE TO INTERFACE THIS CIRCUIT WITH A MICROCONTORLLER AND SAVE MY INPUT AND PLAY WHEN EVER I NEED IT .
or else which circuit will help me to input my own melody through a keyboard and save it and play it
later
