Java Midi - How to get notes from midi whilst it's playing

由 泪湿孤枕 提交于 2019-12-01 10:09:40
问题 I've searched for a while now, and can't find an answer for what I want to do. I want to play a midi file, and display the notes on the screen as it plays. When a note stops playing, it should disappear off the screen. I can play a midi with a sequencer, but have no idea of how to get the notes its playing, or when it stops playing a note. I've looked into ControllerEventListeners and MetaEventListeners, but still don't know how to do this. Any help would be appreciated. 回答1: This is a FAQ.

Can someone show me how to control the volume of an MIDI sequencer without using a sound bank or synthesizer? I want to make the MIDI fade out before continuing to the next MIDI in sequence if(midiplay) { midi = s + savereq; try { //System.out.println("Play MIDI " + midi); if (musicSr != null) { /* This is where I want it to fade out*/ musicSr.stop(); //stop sequencer musicSr.close(); //close sequencer } musicSr = null; musicS = null; File music = new File(midi); if(music.exists()) { musicS = MidiSystem.getSequence(music); } // Create a sequencer for the sequence musicSr = MidiSystem

问题 I´m trying to make a java application that is able to play notes on the computer after detecting a midi device. Once I get the desired midi device I´m seting the receiver to which the device´s transmitter will deliver MIDI messages. device.getTransmitter().setReceiver( new MyReceiver()) ; class MyReceiver looks like: public class MyReceiver implements Receiver { MidiChannel[] channels ; public MyReceiver (){ try { Synthesizer synthesizer = MidiSystem.getSynthesizer(); synthesizer.open();

C/C++ library for reading MIDI signals from a USB MIDI device

由 て烟熏妆下的殇ゞ 提交于 2019-12-01 02:42:30
I want to write C/C++ programs that take input from a MIDI device. The MIDI device connects to my PC using a USB connector. I'm looking for a (C/C++ implemented) library that I can use to read the MIDI signals from the MIDI device through the USB port. I'm happy manipulating the MIDI data once I get it, I just don't want to have to implement the code for its capture. I'm planning on writing my code using the Bloodshed Dev-C++ IDE on Windows XP. PortMidi is another open source cross-platform MIDI I/O library worth checking out. On the other hand, if you are working on a sysex type of app, then

python synthesize midi with fluidsynth

问题 I can't import fluidsynth. [Maybe there's an better module?] I'm trying to synthesize midi from python or pygame. I can send midi events from pygame. I'm using mingus, and it seemed pyfluidsynth would be good / easiest. I think this means pyfluidsynth is installed, but a seperate fluidsynth was not. I don't know if it requires a 'fluidsynth' installer to work? test.py: import fluidsynth print ":(" error: Traceback (most recent call last): File "test.py", line 1, in <module> import fluidsynth

MIDI beginner - need to play one note

I don't know very much about Java's MIDI function. In fact, it utterly bewilders me. what I'd like to do however is just build a simple application that will play one note. How to play a single MIDI note using Java Sound? The support for this out on the web is almost nonexistent, and I am totally at a loss. user2955146 I know this is a really old question, but, as a novice programmer, I had a very difficult time figuring out how to do this, so I thought I would share the following hello-world-style program that gets Java to play a single midi note in order to help anyone else getting started.

play MIDI files in python?

由 久未见 提交于 2019-11-30 11:14:30
I'm looking for a method to play midi files in python. It seems python does not support MIDI in its standard library. After I searched, I found some python midi librarys such as pythonmidi . However, most of them can only create and read MIDI file without playing function. I would like to find a python midi library including playing method. Any recommendations? Thanks! The pygame module can be used to play midi files. http://www.pygame.org/docs/ref/music.html See the example here: http://www.daniweb.com/software-development/python/code/216979 a whole bunch of options available at: http://wiki

ios - mixing midi files, each with own sound font

由 这一生的挚爱 提交于 2019-11-30 10:07:20
I'm looking for a way to mix 2 or more midi files, each with their own sound font files. I've found the following code for one file and tried to do multiple music players but i guess that shouldn't be the right approach. Also i get some weird pop sound every second. So is there any other way, maybe without the musicplayer and musicsequence methods, using only au units? Here's the code i found in another thread: -(void) playMusic:(NSString*) name { NSString *presetURLPath = [[NSBundle mainBundle] pathForResource:@"GortsMiniPianoJ1" ofType:@"SF2"]; NSURL * presetURL = [NSURL fileURLWithPath

How to play MIDI on the iPhone?

由 怎甘沉沦 提交于 2019-11-30 03:58:00
As far as I know, there is not native or third party library available to play MIDI on the iPhone. But there seem to be quite a few apps that do exactly that. What are they using? Any clues? I've written a tutorial on how to play MIDI using CoreMIDI through an AUGraph here . FYI for those going down this road: AVMIDIPlayer was introduced in iOS 8. Seems to work well on device, sim not so much. This worked for me for playing midi file on iPhone: import AVFoundation class MidiPlayer: NSObject { static let shared = MidiPlayer() var musicPlayer: MusicPlayer? var sequence: MusicSequence? func play
