That is the sort of thing - I've already got a couple of chips that do
similar FX - like various alarm sounds - but was looking for something
more musical. That wouldn't irritate so much when hearing it a lot. ;-)

You get a hell of a lot more flexibility with a digital device that
can play any mp3s you can find that you like the sound of.

**** all programming involved in using an arduino or a pi
to play a different mp3 given which digital input it sees and
even to vary the volume with the background noise level.
