Electronic Tanpura

[krishnarajbayar]

Hi everyone..
I am new to this forum, joined with the hope that someone will help me out.
I am a bansuri flute maker. I want to build a digital Tanpura for my requirement. Tanpura is an Indian instrument used to continuously remind in which key you are performing during music recitals, be it vocal or instrumental. It has a pattern of repetitive notes. One can use the samples one or two cycles in length and repeat them using an one time programmable audio ic. Now, the pitch of the basic sound sample has to be varied over a full 2 octaves, in micronotes using an analogue control, a potentiometer. I don't understand how this is achieved. Can anyone help me to build a circuit?
I propose to use the Aplus AP 89341 or some other of this type as it comes cheap. I have absolutely no idea of how to start or what I need. Can anyone help?

There is an Android App for that. Tanpura Droid by Swar Systems. Free.

Thanks a lot for the reply.
In fact I am aware of the application/s for androids, windows etc, but still I want to make my own, so I can control it as I feel, so if there is a way please show me how!
