Hi, I wrote a pygame program that play, loop and queue sounds files. My goal was to keep it short, simple and only one file. The installation and operation instructions are on the bottom of the file. Please see the code below and let me know if you have any suggestions for improvement. Thank you Lenard Lindstrom and Ian Mallett for your assistance! :)

(pygame.org) 2) Copy this file into a folder with sound files. 3) Edit the file to assign the sound files to simples variable at line 11 like this: sound1 = pygame.mixer.Sound("beat1.wav") sound2 = pygame.mixer.Sound("beat2.wav") sound3 = pygame.mixer.Sound("beat3.wav") sound4 = pygame.mixer.Sound("beat4.wav") (and so on..) 4) Edit the file to assign the sound files to MIDI note numbers (C=48, C#=49, D=50 etc) at line 18 like this: if mymidinote == "48": nextsound = sound1 updateScreenAndQueueNextSound() if mymidinote == "50": nextsound = sound2 updateScreenAndQueueNextSound() if mymidinote == "52": nextsound = sound3 updateScreenAndQueueNextSound() if mymidinote == "53": nextsound = sound4 updateScreenAndQueueNextSound() (*Hint watch the spaces in front of the lines, they are important) --------------------------------------------------------------------- Running the Program: 1) Open a terminal window 2) Change to the folder with the program and sound files 3) Enter this command: python -u badpenni.py 4) This prompt will be displayed: 0: interface :ALSA:, name :Midi Through Port-0:, opened :0: (output) 1: interface :ALSA:, name :Midi Through Port-0:, opened :0: (input) 2: interface :ALSA:, name :Virtual Keyboard:, opened :0: (input) See list above. Please enter the number for your midi input device: 6) Enter the number from the list for your MIDI device. 7) Play the assigned notes with your MIDI device. The assigned sounds will play and loop. Newly triggered sounds will be queued to play when the current loop finishes. """ # -------------end badpenni.py file -------------
