## hpr0991 :: Making a Music Sampler with Midi and Pygame

 
Pygame Midi documentation:
https://www.pygame.org/docs/ref/midi.html


Pygame Mailing List:
https://www.pygame.org/wiki/info


Midi.py sample from pygame example folder: 
https://bitbucket.org/pygame/pygame/src/25e3f2cee879/examples/midi.py


Sampler/Sound Looper made from python, pygame and midi:
https://www.pygame.org/project-BadPenni+-+MIDI+Triggered+Sound+Looper-1734-.html 


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()
