     UPDATED 01/22/2013 <> Easy MIDI Notes is based off of another developer's hard work (Abadani, I believe) and some streamlining of code which I added for simplification and ease of use. Example app is designed for those who just want to make use of MIDI without having to spend 90% of the time trying to get a darn note to play. The functionality of this code is similar to Matthew Stride's "Midi Note Generator", but this one is for VB.Net 2008, not C++.Net. Feel free to leave comments or questions though. Featues include (features I added): - 1 file for easy code reuse (simply drop the class in your project and your ready to go) - Simple functions to Stop and Play notes - XML Documentation for ease of code use - Easy Instrument Selection - Easy to follow example program which demonstrates Instrument selection, Volume, Pan, and ModWheel control. This app is aimed at those who love music and want to get started creating MIDI apps, but may not be as skilled at developing (but want to learn).

This code is AMAZING, I cannot thank you enough! Just spend 1 hour hiking through forums looking for a simple MIDI player for (I'm making a piano simulator) and this has actually saved my life. Easy to use and simple to integrate into an existing project. Thank you!

Great code - is there a way of recovering from a 'hang' during a PlayMidiNote? Occasionally my computer hangs in mid-note then crashes and re-boots. Thank you.

Hey Jonathan - In the PlayMIDINote function, in the following area:
Catch ex As Exception
put a breakpoint on that line and run it in Debug mode. See if it can tell you what the exception is and try to see if you can handle it. Let me know what the error is. Right now it is just skipping the error basically.

This code is just what I need for 3D Rhythm Guitar Simulator project I'm working on! Is it fairly straight forward to change the Chorus and Reverb settings? And is there a single note OFF command?

Please see above, I forgot to expose the Note Off command for a single note.

== Go to clsMIDI - LINE 110 after "Sub STOPALLMIDINotes()"
== Add the following code

Sub STOPMIDINote(ByVal Note As Integer)
End Sub

== Add this to Form1 ==

'Click on the Form (not on a label)
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If e.Button = Windows.Forms.MouseButtons.Left Then
m.PlayMIDINote(70, 127) 'Play Note 70
m.STOPMIDINote(70) 'Stop Note 70
End If
End Sub

Thank you for making this excellent code available. Question: Is it possible to define the duration of a note before it begins? I have tried altering m.duration and inst.duration but nothing seems to change.
