VS 2008 : Write MIDI To String?
Feb 18, 2012
Is it possible to load a content of a MIDI file into a string and then save the string back to another file? I have been trying for a while, but no luck...Although I have no error, and the new file, view with notepad, looks the same as the original, but it does not want to play..
Dim urlpath As String = (Application.StartupPath & "UserMIDILibrary"
Dim fname As String = Path.GetFileNameWithoutExtention(pathload)
fname = fname & ".mid"
[code]....

There is this software called Harping midi. You can view it here [URL] I would very much like to recreate this software but extend on it. For example. I would like to be able to pick up the "midi notes" and then translate that to guitar tabs. I would like it to have the same features (channel filters, tempo control) those sort of things. Where would I start???

Is it possible to convert MIDI files (.midi or .mid) into a .wav or .wma file in Visual Basic.NET (2010)? If so:
1: How would this be done?
2: If the output format can be .wma, how can one write the tags (such as artist, album, etc.) to the file in VB.NET?
I am saying .wav or .wma because I know that Microsoft does not have any rights to the MP3 file or something like that.

Hi to all, i really need some help with a piece of code. Im developing an app, which receive midi TIMECODE (MTC) and shows it on a textbox. when i start the app, it runs ok, and shows the mtc on the textbox, but after a few seconds it crashes and shows an error:
"A callback was made on a garbage collected delegate of type 'MidiTesting!MidiTesting.MidiIn_Callback::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called."

So for the past 3 days I've been perusing the internet for a way to run a command when a MIDI signal is sent into VB - where/how should I start? As a matter of fact, I haven't found any way to enable MIDI input, period.

I'm using vb.net and have got the midi out functions working properly. I'm now looking to add midi in functionality to my project and I am confused about the use / syntax of MidiInOpen and the associated midiInProc placeholder function. I think I need to understand and use a Delegate function to point to my Midi in handling procedure but nothing works for me and I can't find a suitable example anywhere.
Does anyone have any advice or examples as to how to implement Midi In in vb.net using the Windows multimedia API please?

I'm trying to play a MIDI file in my VB.NET (VB 2010 Express) and things work well with the code from this other question here on Stack Overflow, which I translated from C to VB.However, I also need to PAUSE, while that code is only for open and stop. I edited the code like this:
Imports System.Runtime.InteropServices
Imports System.IO

I am looking for a way to play the usual MIDI sounds in a VB program. Similar to the beep program (ie console.beep, leading to timer1.start etc.)but instead of an annoying bleep, have a MIDI sound (like a flute, violin, clarinet, etc.). Is this possible in VB 2008?

I just started programming in vb 2008 Using vb studio 2008 and vb 4.0 Running Windows XP Home Edition My question concerns the capabilities of vb to call for the internal sound cards and/or midi synthesizer.Can a module call the sound card for it to play MULTIPLE notes at the same time, notes of fixed frequency and duration?
I have tried programming vb 4 AND vb2008 for them to modify the default BEEP sound: using a code i found on internet:private declare Function Beep lib "kernel32" (byval soundFrequency as int32, byval soundDuration as int32) as int32

So I was working in the forums and on the side bar of some thread I saw this link: [URL]...It turned out to be almost entirely about MIDI, but it made me think that I really need to share some code I wrote a few months ago and see if perhaps there is reason to create what the above thread really asked for.Here's a little background on the following code:
Back in April or so of this year I was doing some spring cleaning and came across the old Yahama PSR-6 synthesizer keyboard I had received one year for Christmas when I was around eight. I remember I used to like the Bagpipe voice because at the low notes it made a good fart sound. For a Toys-R-Us/Radio Shack model keyboard, running on six D-Cell batteries, produced in the early to mid eighties, that was an impressive achievement. LOL Anyway, I always did want to learn to play piano (or keyboard) so I decided to literally dust the thing off, put batteries in it, and fiddle around a bit. A couple YouTube videos later and I was convinced that I wanted to do this. While I was waiting for the thing to ship and arrive, I thought that it really shouldn't be that hard to take a DirectSound SecondaryBuffer object and inject it with sound data which whas calculated based on the harmonic values of musical notes, thereby creating your own synthesizer.
First, I really had little idea what I was doing when I first set about doing this other than the general structure of calculating byte data for notes and stuffing them into a SecondaryBuffer object while it played. I had used direct sound a number of times in a number of ways, but always playing sound data that came from a source (file, stream, etc.). This would be my first attempt at generating sound data for the buffer.
Second, I'm a "code-as-you-learn-learn-as-you-code" kinda guy, so that means that I developed the initial project as I went. I would research a specific portion of the project (and there was a LOT of research to do! lol) and then code it and move on to the next. Of course, this eventually leads to a mess of a project in most cases where the foundation is a bit complex to begin with. So the code I'm posting is the second version of the concept. But even at that, I'm only going to post the primary user control at this point and hold back on the code for the test application I created with it (I will provide a download to the compiled app however). After getting the user control cleaned up (if not ideally redesigned), the second app became a "develop-as-you-go" project for the test application - so it is a bit of a mess now too; but mostly just to look at code-wise - it actually runs pretty well.
Third, there are still a few design issues that could be improved upon in the user control, and a few choices which were made for ease of coding that could be changed for performance. But because of this, other than for a couple of routines, most of the code should actually be pretty straight forward to anyone who's comfortable in VB already.
Ok, on to the example: we are going to create a MusicKeyboard control. This control will draw itself like a pinao keyboard and will render keys for the specified number of full octaves. Clicking a key will play the associated note in the specified voice. Voices will be created using a simple digital oscillator and optional even-noise generator on top of a sine wave form.
To get started, you'll first need to have the DirectX SDK installed. The latest one is available here:[URL]..displaylang=en however the example was created using the version from March 09. There should be no impact from using the newer version.
Once you have the SDK installed, create a new Windows Application and add a new User Control named MusicKeyboard to the project. Note that you could create a Windows Class Library project, but I personally like to develop in an Application for ease of testing and later convert to a class library.You'll need to drag a BackgoundWorker component from the toolbox onto the usercontrol and name it "SynthWorker". Set the worker's WorkerSupportsCancellation property to True.
Now you'll need to add the DirectX reference to the project. You can rightclick the project in the solution explorer and select Add Reference or go to My Project and the References Tab. From the list of .Net references,add Microsoft.DirectX.DirectSound.That should be all we need to get started. In the following posts we'll create a bunch of code files and get the keyboard noise-worthy.Reed Kimble - "When you do things right, people won't be sure you've done anything at all"

I've encountered problems with programming a Guitar Hero game (Frets on Fire) because I just started visual basic, but I know a lot still. I am almost done with button pressing and picking and I can easily get the buttons to scroll, but is there a way to program the buttons that scroll along the screen by using a midi file, like in Frets on Fire. I just don't know how I can get the frets (buttons) to correspond with the song without spending hours programming one song by hand.

i wrote small programm based on joyGetPosEx which read ION Drum Rocker commands as gamepad events and converted it to midi notes signal to MidiYoke or other virtual midi cable.With this program ION Drum Rocker xbox360 drums with cymbals can be used as midi device for PC. Also if edit source for read another command can be used any gamepad device as mididevice.If any someone have ION drum rocker drumset then try to test this program.
I have some issue with it, drumset do not transmit any commands which can be used for sensitivity of hits. But drumset have some sensitivity of hits if connected them to xbox360 console. Maybe problem in HID gamedevice driver, or joyGetPosEx?

I want to build a system that will take the input from an electric guitar and capture the frequency of the sound. and when the frequency is captured, the system identify the chord, and create new controls to represent the audio frequency. i want to use the label as the controls. so when the controls is created, how can i know that the user is click on what label. is there something like label1.click in vb 2005 express? then when the label is all created, i want the system to read all the labels integer as the sound of midi. so i have to assign what integer for what sound.
