RtMidi is a set of C++ classes providing a common cross-platform API for realtime MIDI input and output across Linux (ALSA, JACK), macOS (CoreMIDI, JACK), Windows, Web MIDI, iOS, and Android. It simplifies MIDI device enumeration and message handling with a minimal two-file integration design.
Use cases
- send and receive MIDI messages in a C++ application
- enumerate MIDI devices across platforms
- build a MIDI sequencer or synthesizer
- read input from a MIDI keyboard controller
- write cross-platform music software with one MIDI API
When to choose
- you need realtime MIDI I/O in C++ on multiple operating systems
- you want a minimal dependency (one header and one source file)
- you need MIDI device enumeration with a simple object-oriented API
When to avoid
- you need MIDI timing or scheduling features (RtMidi sends messages immediately)
- you are working in a language other than C++ without bindings
- you need higher-level music abstractions rather than raw MIDI bytes
