The MIDI File Splitter application was designed to be a simple utility to split a MIDI file up into multiple sections based on its markers. It was designed to be used for splitting up the Session Drummer and Pattern Brush MIDI files included with Cakewalks SONAR into individual patterns so that they can be dragged and dropped easily one at a time into SONARs track view.
Splitting the files is as simple as selecting the files you want to split in Windows Explorer and dragging them into the rectangular area at the top of the MIDI File Splitter window (alternatively you can click the "Load" button). By default, a new folder will be created to contain each markers file, with each file being named after the marker. You can also choose for the files not to be placed in a subfolder, or to all go to a specified custom folder (this will default to your desktop).
MIDI File Splitter has a detailed output window that shows you exactly what files it is creating, and reports any errors it encounters (look for messages in Red). MIDI File Splitter will never overwrite an existing file, but you can ask it to generate a new unique filename if the file it is trying to create already exists.
System requirements:
- .NET Framework 2.0

Enhancements:
- First release with its own CodePlex project
- Features updated NAudio code to fix some MIDI file writing bugs
