Introduction

What is librtmidi4
librtmidi4 is:
RtMidi is a set of C++ classes that provides a common API (Application Programming Interface) for realtime MIDI input/output across Linux (native ALSA, JACK, and OSS), Macintosh OS X, SGI, and Windows (DirectSound and ASIO) operating systems. RtMidi significantly simplifies the process of interacting with computer audio hardware. It was designed with the following objectives:
- object-oriented C++ design
- simple, common API across all supported platforms
- only one source and two header files for easy inclusion in programming projects
- MIDI device enumeration
MIDI input and output functionality are separated into two classes,
RtMidiIn and RtMidiOut. Each class instance supports only a single MIDI
connection. RtMidi does not provide timing functionality (i.e., output
messages are sent immediately). Input messages are timestamped with delta
times in seconds (via a double floating point type). MIDI data is passed
to the user as raw bytes using an std::vector
This package provides the shared library.
