Overview

This .NET library provides convenient, threadsafe access to MIDI devices. It does this by binding to the Win32 API with P/Invoke and then wrapping that in an object-oriented API which feels right at home in C# / .NET.

For a taste of what the API offers, check out the example snippets.

Features

• MIDI

  • Easy access to MIDI input and output devices.
  • Register input handlers using C# events / delegates.
  • Full support for sending and receiving Note On, Note Off, Control Change, Program Change, Pitch Bend, and raw System Exclusive (SysEx) messages.
  • Convenient enums for General MIDI Channels, Pitches, Instruments, Controls, and Percussions.

• Scheduling

  • A powerful scheduler that lets you schedule MIDI messages, pause, unpause, and adjust beats-per-minute while it runs.
  • Support for callback messages, so you can schedule call-outs to your own code at specific instants. Callback messages are scheduled just like MIDI messages, so they are subject to pause, unpause, and beats-per-minute as well.
  • Callback messages can schedule additional messages when triggered (self-propagating messages), which allows for a flexible continuation-passing style of control.
  • Built-in NoteOnOffMessage schedules the Off message when the On message triggers.

• Music Theory

  • Octave-independent Note class which differentiates among enharmonic variants (eg, D♯; and E♭). Notes can be resolved to specific pitches as needed.
  • Scale class built from tonic note and ascent pattern. Includes built-in patterns (Major, Melodic Minor Ascending, Chromatic, etc).
  • Chord class built from tonic note, ascent pattern, and inversion. Includes built-in chord patterns (Major, Seventh, Diminished, etc).

• Documentation

  • Interactive demo programs, both console and GUI.
  • Comprehensive API documentation.
  • Unit tests.

Not-Yet-Features

• No MIDI file I/O.

Requirements

• .NET Framework 3.5.
• Visual Studio C# 2008 (Express or Professional) or later.
• winmm.dll, the Win32 multimedia API which is standard on all modern Windows installs.
