Midi implementation within .Net

由 坚强是说给别人听的谎言 提交于 2019-12-05 04:04:32
Does anyone have any guidance or recommendations for writing a MIDI-based application in C# Winforms? I have recently bought a new effects pedal that has a full MIDI implementation (or so I'm led to believe) but the manufacturers have seen fit to not release a librarian / patch editing application. I have virtually no experience of MIDI beyond plugging a keyboard into another MIDI device, but it can't be that hard, right? ;-) Thanks in advance. check out this links, this is maybe what you are looking for http://www.codeproject.com/KB/audio-video/MIDIToolkit.aspx http://www.codeproject.com/KB

How to get Note On/Off messages from a MIDI sequence?

由 被刻印的时光 ゝ 提交于 2019-12-05 00:33:32
问题 I am hoping to get notifications of note on/off events in a playing MIDI sequence to show the notes on a screen based (piano) keyboard. The code below adds a MetaEventListener and a ControllerEventListener when playing a MIDI file, but only shows a few messages at the start and end of the track. How can we listen for note on & note off MIDI events? import java.io.File; import javax.sound.midi.*; import javax.swing.JOptionPane; class PlayMidi { public static void main(String[] args) throws

How to deal with multiple identical MIDI USB devices

由 会有一股神秘感。 提交于 2019-12-05 00:02:49
问题 My c# application must use multiple identical USB MIDI interfaces which are all from the same manufacturer. In device manager, all devices appear with the same driver name / CLSID - only the PNPDeviceID is different. When I list all MIDI inputs / outputs (using MIDI-dot-net), they appear as follows: ACME-MIDI: Port 1 1- ACME-MIDI: Port 1 2- ACME-MIDI: Port 1 Unfortunately, those names are not always the same for the same device. The ports of device 1 appear sometimes as "ACME-MIDI: Port 1"

Generating a FileDescriptor on Android without first opening a file

由 醉酒当歌 提交于 2019-12-04 14:32:56
In Android, is it possible to generate a FileDescriptor directly from a byte array, without having to open a file first? In Android 2.2, I am generating a MIDI file on the fly, and then playing it back using MediaPlayer. I've included the text of the Main.java file that does this successfully below. So far so good. However, this process first calls... FileOutputStream outputStream = openFileOutput(file, MODE_PRIVATE); outputStream.write(byteStream); outputStream.close(); ... to write out the file, and then calls... FileInputStream inputStream = new FileInputStream(midifile); FileDescriptor

midi file parsing, unrecognised event type

由 社会主义新天地 提交于 2019-12-04 11:52:33
I have a problem trying to parse a midi file. I am trying to parse the notes files used by the frets on fire game (it just uses midi files so i don't think this is relevent) if any of you are familiar with it, the problem i am having is a general midi problem. I have a file with a track called guitar part, the hex, as viewed in a hex editor is as follows: 4D 54 72 6B 00 00 1E 74 00 FF 03 0B 50 41 52 54 20 47 55 49 54 41 52 A9 20 90 61 40 9A 20 61 00 83 60 63 40 BC My program parses this fine as follows: 4D M 54 T 72 R 6B K 00 < -- 00 size of 1E track part 74 -- > 00 time of this event FF event

MIDI instrument listing?

由 ぃ、小莉子 提交于 2019-12-04 11:33:55
问题 I have recently implemented a MIDI Beatbox from the code in Head First Java and would really like to do more with Java's MIDI capabilities. I thought that I might start by adding more, non-percussive instruments to the existing code, but I cannot seem to find a straightforward listing of the available instruments and their int keys. Does such a listing exist anywhere for the Soundbank that ships with the JDK? 回答1: DYM like this? import javax.sound.midi.*; import javax.swing.*; class

How can I convert between midi to wav/mp3 in c#?

由 我与影子孤独终老i 提交于 2019-12-04 11:00:59
问题 I started a small project which includes working with MIDI files. I've been wondering, is there any C# or VB.Net code that peforms that cast between MIDI and WAV files? 回答1: You could try to somehow interface with Timidity, which is Open Source: TiMidity++ is a software synthesizer. It can play MIDI files by converting them into PCM waveform data; give it a MIDI data along with digital instrument data files, then it synthesizes them in real-time, and plays. It can not only play sounds, but

How to load custom DLS or SoundFonts to Android MIDI

由 淺唱寂寞╮ 提交于 2019-12-04 08:08:30
I have an application that plays MIDI files through the SONiVOX EAS library. Is it possible to load my own DLS or SoundFont wavetables into the player and have the library use these sounds for MIDI playback? Ok, I change my answer completely, as the Jet Creator obviously wasn't what you were looking for. I took a look into the eas library, and found, ( in eas.h ) /*---------------------------------------------------------------------------- * EAS_LoadDLSCollection() *---------------------------------------------------------------------------- * Purpose: * Downloads a DLS collection * * Inputs:

Synthesia plays well midi file without any note off event?

问题 I have a .mid file - this one specifically. Appart from the header chunk here is the relevant part of the midi. The first track chunk contains only meta events and is described as 4D 54 72 6B 00 00 00 52 // Track chunk #1 info 00 FF 58 04 04 02 18 08 // Meta event 00 FF 59 02 00 00 // Meta event 00 FF 51 03 15 CC 5B // Meta event 81 88 70 FF 51 03 16 E3 60 // Meta event 81 70 FF 51 03 1A 28 6E // Meta event 81 70 FF 51 03 1C 9C 38 // Meta event 81 70 FF 51 03 1E 84 80 // Meta event 81 70 FF

Android 6.0+: No Sound Using the New MIDI API

由 余生颓废 提交于 2019-12-04 04:46:20
问题 I am using the new MIDI API in order to play some MIDI notes. However, I am unable to hear any sound, nor any exception is being thrown. The code for the same is as follows: //initialising the MidiReceiver private MidiReceiver midiReceiver; midiReceiver = new MidiReceiver() { @Override public void onSend(byte[] msg, int offset, int count, long timestamp) throws IOException { } }; /*Then in my loop containing note_on or note_off events*/ byte[] buffer = new byte[32]; int numBytes = 0; int
