About

Abundant Music was written by Per Nyblom. The original source code can be found here: https://github.com/pernyblom/pernyblom.github.io/tree/master/abundant-music

Check out the original Abundant Music application here: https://pernyblom.github.io/abundant-music/index.html

I created AbundantMusic.NET because I wanted an easy way to generate MIDI files and play them back in C# based applications. I looked through the Abundant Music source code starting with the exportMidi() function in composemain.js. I copied the relevant files and modified some code to work with JavaScriptEngineSwitcher. The biggest change I made was removing the Web Workers dependency. This was to make the code compatible with JavaScriptEngineSwitcher.

Getting Started

Simply run the Generate method with any string of your choosing. The resulting MemoryStream is your MIDI file. Now that you have the MemoryStream, you can write the file to disk or use it elsewhere in your program.

...
using AbundantMusic.NET;
...
MidiComposer composer = new MidiComposer();
Stream midiFile = composer.Generate("my seed string");
...

See DemoPlayer for a more detailed example.

Future Development

Cleaning up the modified JavaScript files is the number one thing on my todo list. It works as is, but the readability and code quality need to be improved.

Error checking should also be implemented within the AbundantMusic.NET project.
