Sample values that populate midi_events variable:
Middle C note key press (notice the data1 is 60 and data2 is 127)
<Event(34-Unknown {'status': 144, 'vice_id': 2, 'timestamp': 6701, 'data1': 60, 'data3': 0, 'data2': 127})>
Middle C note key release (notice the data1 is 60 and data2 is 0)
<Event(34-Unknown {'status': 128, 'vice_id': 2, 'timestamp': 6764, 'data1': 60, 'data3': 0, 'data2': 0})>
Middle C# note key press (notice the data1 is now 61)
<Event(34-Unknown {'status': 144, 'vice_id': 2, 'timestamp': 206684, 'data1': 61, 'data3': 0, 'data2': 127})>
Python code snippet that pulls the note number from the midi_events list and appends an "off" string if it is a key release.
if str(midi_events[0][0][2]) != "0":
midinote = str(midi_events[0][0][1])
else:
midinote = str(midi_events[0][0][1]) + "off"
Controlling sounds with if statements and our midinote variable:
distbassrollloop = pygame.mixer.Sound("7FullCircleDistBassRollLoop.wav")
distsnarerollloop = pygame.mixer.Sound("7FullCircleDistSnareRollLoop.wav")
distbass = pygame.mixer.Sound("7FullCircleDistBassPad.wav")
distsnare = pygame.mixer.Sound("7FullCircleDistSnare.wav")
if midinote == "48":
distbass.play()
if midinote == "49":
distbassrollloop.play(1000)
if midinote == "49off":
distbassrollloop.stop()
if midinote == "50":
distsnare.play()
if midinote == "51":
distsnarerollloop.play(1000)
if midinote == "51off":
distsnarerollloop.stop()
