The API for the MIDI messages is relatively straightforward. The protocol consists primarily of MIDI messages which represent the various actions like adjusting a knob or striking a note on a keyboard. The MIDI protocol format is described later in this section, but first, we'll cover the API for representing it. Once we dive into those, we're going to cover the MIDI protocol because both files and the MIDI device API rely on the MIDI protocol format. This is how you read musical keyboard key presses or make sound with a synthesizer (including the wavetable synthesizer built into your computer's sound hardware) The other portion deals with communicating and querying MIDI devices. One is the portion dealing with MIDI files and in-memory sequences that provide manipulation and querying. There are two major parts of this library, though they are completely and seamlessly integrated with one another. When I get further along I'll write an article about them. I am still working on these so they are what I'd consider rough proofs.

Update 7: Fixed MidiSequence.ToNoteMap() bug and added MidiUI project which contains the beginnings of user interface controls for MIDI sequencing, including a piano control and a MIDI sequence visualizer control. Update 6: MidiStream now derives from MidiOutputDevice It covers some of the the low level internals behind MidiStream in particular. Update 5: Not directly an update to this particular article, but I've published a related article here on how I get some of the trickier P/Invoke in this library to work. Update 4: Finally added MidiSequence.AddAbsoluteEvent() which is an optimized way to add a single absolutely positioned MidiEvent to a MidiSequence without having to resort to Merge() which is a bit more complicated and less efficient. Get this update, especially if your app is randomly crashing. It turns out it just wasn't doing with the memory what I thought it was. Anyway, I fixed that. It worked, until I "optimized" it to reduce unmanaged heap fragmentation a little, but it couldn't take the optimization for reasons.

It turns out I misunderstood something about the way the MIDI driver api works, and it's not very well documented so I didn't have a lot of help. Update 3: Fixed stability issue in MidiStream. As before you can still use MidiSequence.GetContext(position).Time to get a time from a position. Update 2: Added a few MidiSequence improvements to help with locating positions within a track based on time, like GetPositionAtTime(), and GetNextEventAtPosition(). It doesn't get the timing perfect because I can't get the latency low enough consistently to make it super accurate, but I've provided it in the interest of completeness. Update: Added experimental tempo synchronization functionality to the library. I've produced articles on using bits and pieces of it, but never a comprehensive guide, and I aim to do that here. In the process, MidiSlicer moved from a first class application to just another demo project, so the solution is still named MidiSlicer - I'm stuck with the GitHub of that name. Eventually, I had wrapped maybe 90-95% of the API, and had a battery of MIDI manipulation functions for searching and modifying in memory sequences and files. I added some more demos, streaming support, MIDI input support, device enumeration and more. That library grew as I added more features and shored up what I had.

I also wrote some remedial playback code at first, which used the 32-bit Windows MIDI API.
In the process of creating such a tool, I made a Midi assembly that contained the core MIDI file manipulation options. I do some MIDI sequencing and recording and I found it helpful to be able to splice sections out of a MIDI file, but I didn't have a tool that made it easy to do.
