 DryWetMIDI is the .NET library to work with MIDI data and MIDI devices. It allows:
 
-* Read, write and create [Standard MIDI Files (SMF)](https://www.midi.org/specifications/file-format-specifications/standard-midi-files). It is also possible to read [RMID](https://www.loc.gov/preservation/digital/formats/fdd/fdd000120.shtml) files where SMF wrapped to RIFF chunk. You can easily catch specific error when reading or writing MIDI file since all possible errors in a MIDI file are presented as separate exception classes.

 * [Send](https://melanchall.github.io/drywetmidi/articles/devices/Output-device.html) MIDI events to/[receive](https://melanchall.github.io/drywetmidi/articles/devices/Input-device.html) them from MIDI devices, [play](https://melanchall.github.io/drywetmidi/articles/playback/Overview.html) MIDI data and [record](https://melanchall.github.io/drywetmidi/articles/recording/Overview.html) it. This APIs support Windows and macOS.
 * Finely adjust process of reading and writing. It allows, for example, to read corrupted files and repair them, or build MIDI file validators.
 * Implement [custom meta events](https://melanchall.github.io/drywetmidi/articles/custom-data-structures/Custom-meta-events.html) and [custom chunks](https://melanchall.github.io/drywetmidi/articles/custom-data-structures/Custom-chunks.html) that can be written to and read from MIDI files.
