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:
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")
note_on = [0x90, 60, 112] # channel 1, middle C, velocity 112
note_off = [0x80, 60, 0]
midiout.send_message(note_on)
time.sleep(0.5)
midiout.send_message(note_off)
del midiout
