You must’ve seen the Harry Potter chapter written with markov chains / predictive text (not AI, I should point out). I went to the site, and thought, I wonder what this could do with music written in the text ABC notation format. So, grabbing the same source files that gave us Mancis the Poet (where I used RNN to generate the complete files), I loaded Botnik with Cape Breton Fiddle tunes. Then I generated a text, clicking madly in the middle of the interface. The result:

A ab|ca fe|dfba f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a|
Da|bf{g}fe b a2 f2|d a ab|ca fe|dfba f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a| f2 ed|ceac b2a|

Which, when you add some made-up metadata like so to the front:

X:1
T:Botnik Autogenerator Reel
R:reel
C:algorithmic
O:21st century Canadian
B:
N:
Z:
M:C|
L:1/8
Q:108

…becomes a file that can be turned into MIDI, thence mp3. You can generate your own fiddle line with this corpus: http://botnik.org/apps/writer/?source=bbbedbbada64da161a2055387eb50dae.

And here you go: the music notated above as MIDI piano:
