Basic Stamps and Music

Hello all,
I do not have any of the basic stamps or have ever used one.
I am considering using one to simulate a wind instrument.
With the basic stamp as a stand alone device could I create
data for each note and play each note simultaniously depending
on what buttons are pressed to convincingly create a flute?
I know there is an add on device for speech recognition and
for playing .wav files put I want to avoid extra devices for
now.
I know I may need to build an audio mixer to output to a single
speaker or headphone.
Would this be a practical application and are there some
recommended tools to help with this project?
Thanks,
Alan

    You mentioned playing notes simultaneously -- is this what you really mean?

    The Basic Stamp is not going to produce more than one note at a time. You
    can have it output two frequencies at the same time, but its not truly
    polyphonic.

    Probably not. The BASIC Stamp can generate tones, but not in the manner that
    the device you suggest requires. You could pre-program a simple tune, but
    the output would require serious filtering to approximate the sound of a
    flute.

    Another thought ... you probably could use the Stamp as a custom interface
    for a midi controller. Of course, you'd require a midi instrument to play
    the notes.

    Oddly enough, I've done exactly that.

    The art installation I did for burning man this year was a stamp-based
    project which took class IIIa laser emitters / detectors and generated
    midi data which got interpreted by a synth and amplified. Works good. IF
    you want to see a board design or a CAD drawing I can supply it ; oddly
    enough, I have gerber files, but no schematic. Basically, the board uses a
    BS2 to have 15 input lines from switches (in this case photoresistors) and
    the final line as an I/O line for the midi data. It's a pretty simple
    circuit ; the programming was much more complicated. But I'm a programmer
    by history, so it worked out well that way.

    Check out http://www.zenchemical.com/burningman/congruence for a very
    brief project description and some pictures, and let me know if you have
    any questions about stamp/midi interfacing. I also have some extra boards
    which I might let go ; the fabrication cost me $150 for 8 of them.

    Thanks Sean,
    I will think about this method, it sounds good.
    Thanks all for your help an ideas.
    Alan
