High performance MIDI I/O routing through a WebSocket.
A mashup of RtMidi and a PHP WebSocket library to allow MIDI I/O via javascript.
Tested on Mac 10.10.5 , Hercules DJ Control Instinct USB and Firefox/Safari/Chrome.
Should work on Linux and (with some work) Windows.
EDIT: for fedora 25 sudo yum install alsa-lib-devel
Also, in case the program tests/gomidi doe not get found by the tests/Makefile then use the tests/Makefile-BAK1 instead. ///////
./configure
make
cd tests
make
./gomidi
OR
./forever.sh
For the WebSocket server:
cd websocket
php process-midi.cpp
Default WebSocket on port 9001

RtMidi - a set of C++ classes that provide a common API for realtime MIDI input/output across Linux (ALSA & JACK), Macintosh OS X (CoreMidi & JACK) and Windows (Multimedia).
By Gary P. Scavone, 2003-2014.
This distribution of RtMidi contains the following:
doc: RtMidi documentation (see doc/html/index.html) tests: example RtMidi programs
On unix systems, type "./configure" in the top level directory, then "make" in the tests/ directory to compile the test programs. In Windows, open the Visual C++ workspace file located in the tests/ directory.
If you checked out the code from git, please run "autoconf" before "./configure".
OVERVIEW:
RtMidi is a set of C++ classes (RtMidiIn, RtMidiOut, and API specific classes) that provide a common API (Application Programming Interface) for realtime MIDI input/output across Linux (ALSA, JACK), Macintosh OS X (CoreMIDI, JACK), and Windows (Multimedia Library) operating systems. RtMidi significantly simplifies the process of interacting with computer MIDI hardware and software. It was designed with the following goals:
- object oriented C++ design
- simple, common API across all supported platforms
- only one header and one source file 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.
