Should all tracks be combined like this? Is it possible to keep each instrument separately within a jam file? Or at least output one jam file per midi track.

midi files are generally messy, it's non-trivial to group tracks into instruments (as @craffel can attest), and the mapping between tracks<--> instruments is not 1-1. So this is the simplest solution, which I'd keep as the default behavior. That said, I don't see why we couldn't provide an optional parameter that would allow you to ask for each instrument to go in a separate annotation (where instruments are defined using the grouping used in pretty_midi), and if you really think it'd be useful we could consider creating an annotation per-track too (messier).

Well, it's trivial to separate MIDI notes by track+program number (this is what pretty_midi, and basically any MIDI parser does) but there is not a 1-1 mapping between program number and instruments in a given song.

Sure, even though there's no standardized way of how to use the tracks in MIDI and for what instruments, etc., it still seems like useful information is lost when everything is merged, no?

provide an optional parameter that would allow you to ask for each instrument to go in a separate annotation (where instruments are defined using the grouping used in pretty_midi)

This. 👍

Instead of two lines, shouldn't this really be a case insensitive search (e.g. song.MiD is actually a valid extension on some OS:es)? Also .midi is a very common extension (even Windows doesn't rely on FAT anymore).

This could be more elegant, yes, it was just the simplest way to use find_with_extension without modification. In the short-term iterating over a list of accepted file extensions (mid, MID, midi, MIDI) would do the trick, though perhaps building case insensitivity into find_with_extension would be a nice thing to have @bmcfee ?

print(len(midi_files))

for mf in midi_files:

jams_file = (
os.path.join(out_dir, os.path.basename(mf)[:-3] + "jams"))
jams.util.smkdirs(os.path.split(jams_file)[0])

Why have a logger if it's only used for profiling elapsed time? Seems better to just remove it entirely and let external profilers measure main() if needed.

The logging is intended for end users who are not necessarily python coders and just need to use the script to convert a dataset. It's the same in all converters pretty much.
