midi

问题 Ok, this is what I got: import pygame import sys from pygame.locals import * bif="bg.jpg" mif="pkmn.png" sif="bubble.png" song_1="testaudio.mid" pygame.init() FPS = 30 # FPS FPSCLOCK = pygame.time.Clock() # FPS screen = pygame.display.set_mode ((600,375),0,32) intro=pygame.mixer.Sound(song_1) intro.play() background = pygame.image.load(bif).convert() pygame.mouse.set_visible(0) char = pygame.image.load(mif).convert_alpha() x = screen.get_width()/2 - char.get_width()/2 y = screen.get_height()

问题 My goal is to listen to a MIDI to USB adapter that is connected to my guitar pedalboard switcher. When a program change, (PC) message is received, play the appropriate mp2 file. I've tried a number of different Python MIDI modules and pygame has got me the closest. Below is the code I have been tinkering with and it is printing messages when I send program messages for the pedal switcher. I just do not know how to extract and interpret what I need. For instance, the pedal switcher sends a PC

问题 I am using the sequence.getResolution() built in method to extract how long a beat is in milliseconds. It works for some songs but not all. For example, for the song 'sweet home alabama' it returns a beat of 384 MS, however in real life the actual beat length is 612 MS. This works for countless other songs and only works for one of the songs that I am working with. Any other way to correctly extract the bpm or tempo of a MIDI file using java would be greatly appreciated 回答1: The tempo is

问题 I know MIDI allows me to read the state of a MIDI Foot Controller by catching a MIDI Message indicating a Control Change. But what if the user has not touched/changed the control yet? Am I still able to read the state/value? What would be the way to do that? This is my code for catching Midi Messages using OSX CoreMIDI void initMidi() { MIDIClientRef midiClient; MIDIPortRef inputPort; OSStatus status; MIDIEndpointRef src; status = MIDIClientCreate(CFSTR("testing"), NULL, NULL, &midiClient);

问题 I'm trying to use music21 to convert multi-track midi files into array of notes and durations per each track. For example, given a midi file test.mid with 16 tracks in it, I would like to get 16 arrays of tuples, consisting of (pitch, duration (plus maybe position of the note)). Documentation for music21 is rather difficult to follow, and I would really appreciate any help on this.. 回答1: There is more than one way to do this in music21, so this is just one simple way. Note that the durational
