Usage
========
Here's a quick example of how to use **python-rtmidi** to open the first
available MIDI output port and send a middle C note on MIDI channel 1:
.. code-block:: python
import time
import rtmidi
midiout = rtmidi.MidiOut()
available_ports = midiout.get_ports()
if available_ports:
midiout.open_port(0)
else:
midiout.open_virtual_port("My virtual output")
with midiout:
# channel 1, middle C, velocity 112
note_on = [0x90, 60, 112]
note_off = [0x80, 60, 0]
midiout.send_message(note_on)
time.sleep(0.5)
midiout.send_message(note_off)
time.sleep(0.1)
del midiout
.. note:: On Windows it may be necessary to insert a small delay after the
last message is sent and before the output port is closed, otherwise
the message may be lost.
More usage examples can be found in the examples_ and tests_ directories
of the source repository.
