Jeff Bridges asks about fitting a set of bagpipes into a player piano.
Anything is possible, but the severe limitation here is that a standard
set of bagpipes does not play the chromatic scale.  There are many
nationalities of bagpipes and some, like the Irish bagpipe, are almost
chromatic.  The more common Scottish bagpipe is nearly diatonic (white
notes only ), except C and F are about a quarter tone sharp.  I suggest
these issues alone make it not worth the effort to incorporate with a
'normal' mechanical musical instrument.

Another problem is the method of musical articulation.  There is no
valve between the wind bag and the drones or chanter pipes so there is
a continuous sound from all.  It is impossible to 'tongue' a note as on
a normal wind instrument, so this is effected by 'graces', usually
where all fingers are raised from the chanter momentarily and replaced.

This, along with the unusual scale, gives the bagpipes its
characteristic sound.  The mechanical requirement of graces will not
already be encoded into a standard music roll, so if required would
have to be derived either electronically or mechanically according to
your whim.

A stand-alone player bagpipes would be a better bet.  Here, you could
easily provide the mechanical finger pads on the chanter, but you would
need to arrange your music from scratch.  Another, not insurmountable
problem is to provide a two pressure wind supply so you can get the
upper range of overblown notes.

Who's going to be the first with a player bagpipes?
