Performance Utility Tools

Some of the exercise packages include several utility and test programs. These are all standalone scripts using Python 3 and a few additional packages as described in Python 3 Installation.

The following scripts may be browsed in the Python MIDI tools directory on the course site.

list_MIDI_ports.py

Command-line test program for identifying available MIDI ports by printing a list of the MIDI input and output ports available via python-rtmidi. There are no options, just running it will print a list of port names:

python3 list_MIDI_ports.py

The full code follows, but may also be downloaded from list_MIDI_ports.py.
