Another Python MIDI file library (which I wrote based on a really old
predecessor) is miditk-smf:

https://pypi.org/project/miditk-smf/

It uses an event-based approach, i.e. it works great for filtering and
changing MIDI events as they are read in. Here's an example of how you
would map MIDI program change events from one program number to another,
optionally only on selected MIDI channels or tracks in the MIDI file:

If you want to change the timing of events, the filtering approach is
not appropriate. miditk-smf also has support for parsing a complete MIDI
file into a MidiSequence object, which is a container for all the events
of the file, but unfortunately there is no direct support for writing
these events back to MIDI file yet.
