python-rtmidi uses the de-facto standard Python distutils and setuptools
based packaging system and can be installed from the Python Package Index via
pip. Since it is a Python C(++)-extension, a C++ compiler and build
environment as well as some system-dependent libraries are needed to install,
unless wheel packages with pre-compiled binaries are available for your system.
See the Requirements section below for details.

From PyPI¶

If you have all the requirements, you should be able to install the package
with pip:

$ pip install python-rtmidi

This will download the source distribution from python-rtmidi’s PyPI page,
compile the extension (if no pre-compiled binary wheel is available) and
install it in your active Python installation. Unless you want to change the
Cython source file _rtmidi.pyx, there is no need to have Cython installed.

Note

On some Linux distributions, e.g. Debian, which support both Python 2 and
Python 3, pip may installed under the name pip2 resp. pip3. In this
case, just pip2 instead of pip if you’re still using Python 2 (not
officially supported), or pip3 if you are using Python 3.

python-rtmidi also works well with virtualenv and virtualenvwrapper. If you
have both installed, creating an isolated environment for testing and/or using
python-rtmidi is as easy as:

$ mkvirtualenv rtmidi
(rtmidi)$ pip install python-rtmidi

If you want to pass options to the build process, use pip’s install-option
option. See the From Source section below for available options.

Pre-compiled Binaries¶

Pre-compiled binary wheels of the latest python-rtmidi version for Windows and
macOS / OS X are available on PyPI for several major Python versions. If you
install python-rtmidi via pip (see above), these wheels will be selected by pip
automatically, if you have a compatible Python and Windows or macOS version.

The Windows binary wheels are compiled with Windows MultiMedia API support and
are available in 32-bit and 64-bit versions. The macOS / OS X binary wheels are
compiled with CoreMIDI support and are only available in 64-bit versions for
OS X 10.6 and later. If you need JACK support on OS X, you need to compile
python-rtmidi yourself (see the macOS section below for details).

From Source¶

To compile python-rtmidi from source and install it manually without pip, you
can either download a source distribution archive or check out the sources from
the Git repository.

While the steps to get the sources differ, the actual compilation step consists
only of the usual python setup.py install command in both cases.

setup.py recognizes several options to control which OS-dependent MIDI
backends will be supported by the python-rtmidi extension binary it produces
plus other options to control compilation of the RtMidi C++ library:

Option	Linux	mac OS / OS X	Windows	Note
`--no-alsa`	supported			Don’t compile in support for ALSA backend.
`--no-jack`	supported	supported		Don’t compile in support for JACK backend.
`--no-coremidi`		supported		Don’t compile in support for CoreMIDI backend.
`--no-winmm`			supported	Don’t compile in support for Windows MultiMedia backend.
`--no-suppress-warnings`				Don’t suppress RtMidi warnings to stderr.

Support for each OS dependent MIDI backend is only enabled when the required
library and header files are actually present on the system. When the options
passed to setup.py change, it may be necessary to remove previously built
files by deleting the build directory.

You can also pass these options to setup.py when using pip, by using its
--install-option option, for example:

pip install python-rtmidi --install-option="--no-jack"

From the Source Distribution¶

To download the python-rtmidi source distribution archive for the current
version, extract and install it, use the following commands:

$ pip download python-rtmidi
$ tar -xzf python-rtmidi-1.4.9.tar.gz
$ cd python-rtmidi-1.4.9
$ python setup.py install

On Linux or macOS / OS X, if you want to install python-rtmidi into the
system-wide Python library directory, you may have to prefix the last
command with sudo, e.g.:

$ sudo python setup.py install

The recommended way, though, is to install python-rtmidi only for your current
user (which pip does by default) or into a virtual environment:

$ python setup.py install --user

From the Source Code Repository¶

Alternatively, you can check out the python-rtmidi source code from the Git
repository and then install it from your working copy. Since the repository
does not include the C++ module source code pre-compiled from the Cython
source, you’ll also need to install Cython >= 0.28, either via pip or from its
Git repository. Using virtualenv / virtualenvwrapper is strongly recommended
in this scenario:

Make a virtual environment:

$ mkvirtualenv rtmidi
(rtmidi)$ cdvirtualenv

Install Cython from PyPI:

(rtmidi)$ pip install Cython

or from its Git repository:

(rtmidi)$ git clone https://github.com/cython/cython.git
(rtmidi)$ cd cython
(rtmidi)$ python setup.py install
(rtmidi)$ cd ..

Then install python-rtmidi:

(rtmidi)$ git clone https://github.com/SpotlightKid/python-rtmidi.git
(rtmidi)$ cd python-rtmidi
(rtmidi)$ git submodule update --init
(rtmidi)$ python setup.py install

Requirements¶

Naturally, you’ll need a C++ compiler and a build environment. See the
platform-specific hints below.

If you want to change the Cython source file _rtmidi.pyx or want to
recompile _rtmidi.cpp with a newer Cython version, you’ll need to install
Cython >= 0.28. The _rtmidi.cpp file in the current source distribution
(version 1.4.9) is tagged with:

/* Generated by Cython 0.29.23 */

RtMidi (and therefore python-rtmidi) supports several low-level MIDI frameworks
on different operating systems. Only one of the available options needs to be
present on the target system, but support for more than one can be compiled in.
The setup script will try to detect available libraries and should use the
appropriate compilations flags automatically.

Linux: ALSA, JACK

macOS (OS X): CoreMIDI, JACK

Windows: MultiMedia (MM)

Linux¶

First you need a C++ compiler and the pthread library. Install the
build-essential package on debian-based systems to get these.

Then you’ll need Python development headers and libraries. On debian-based
systems, install the python-dev package. If you use the official installers
from python.org you should already have these.

To get ALSA support, you must install development files for the libasound2
library (debian package: libasound2-dev). For JACK support, install the
libjack development files (if you are using Jack1, install libjack-dev,
if you are using Jack2, install libjack-jackd2-dev).

macOS (OS X)¶

Install the latest Xcode version or g++ from MacPorts or homebrew
(untested). CoreMIDI support comes with installing Xcode. For JACK support,
install JackOSX with the installer or build JACK from source.

Note

If you have an old version of OS X and Xcode which still support building
binaries for PPC, you’ll have to tell distribute to build the package only
for i386 and x86_64 architectures:

env ARCHFLAGS="-arch i386 -arch x86_64" python setup.py install

User Contributed Documentation¶

The python-rtmidi wiki on GitHub contains some user contributed
documentation for additional installation scenarios. Please check these, if
you have trouble installing python-rtmidi in an uncommon or not-yet-covered
environment.

Problem with rtmidi

Got the following error while pulling rtmidi.

The fix for this from what I understand is to install libasound2. However, since I can’t use sudo, what is the alternative for this?

Thanks

From the docs for RtMidi it looks like Jack is an alternative to asound. You might be able to download and compile it from its home page, though you’d need to know how compile C++ code.

You’ll need to pass in an include path and a library path to the command you are using to install them. Are you using pip?

So you mean compile it and pip it in? Have not done this Before. Any link for a guide? Do I need to put it on a server I guess? Github works?

Thanks

It’s part of the pakacage I am piping from magenta. It always breaks when it tries to install rtmidi.

I looked up the rtmidi forum and they suggested that I need install libasound2 via sudo, but sudo is not supported.

OK, so if you’re using pip, you can use its --global-option flag; this allows you to pass flags down the setup.py inside the pip package, which in turn means that they can be used by the C compiler.

The C compiler uses its -I option along with a colon-separated path to specify directories for include files, and -L for library files, and setup.py will pass those along.

All this means that if you’ve downloaded and compiled Jack to /home/chaoxin/jack, and it has put its include files in /home/chaoxin/jack/include and the libraries inside /home/chaoxin/jack/lib, you should be able to install the package by doing

pip3.6 install --user yourpackage --global-option="-L/home/chaoxin/jack/lib" --global-option="-I/home/chaoxin/jack/include"

Using API_UNIX_JACK on Ubuntu prevents note off messages from taking effect. Changing the api to API_LINUX_ALSA solves the issue as expected. Is any one else experiencing this issue? This is my wrapper function around send_message of MidiOut (do not consider the pitch bending part):

MOUT = rtmidi.MidiOut(name="Computil Client", rtapi=rtmidi.API_UNIX_JACK)

def play_note(keynum=60, dur=1, ch=1, vel=127):
    # 3 bytes of NON/NOF messages:
    # [status byte, data byte 1, data byte 2]
    # status byte, first hex digit: 8 for note off, 9 for note on
    # data byte 1: pitch, data byte 2: velocity
    ch -= 1
    non_msg = (NOTE_ON + ch, keynum, vel)
    nof_msg = (NOTE_OFF + ch, keynum, vel)

    # PITCH BENDING #
    fpart, ipart = modf(keynum)
    # https://sites.uci.edu/camp2014/2014/04/30/managing-midi-pitchbend-messages/
    bend_center = 8192
    bend_max = 16384
    semitone_bend_range = (bend_max - bend_center) / 2
    bend_val = bend_center + int(fpart * semitone_bend_range)
    bend_msg = [PITCH_BEND + ch, bend_val & 0x7f, (bend_val >> 7) & 0x7f]
    bend_reset_msg = [PITCH_BEND + ch, bend_center & 0x7f, (bend_center >> 7) & 0x7f]

    try:
        # MOUT.send_message(bend_msg)
        MOUT.send_message(non_msg)
    finally:
        time.sleep(dur)
        MOUT.send_message(nof_msg)
        # MOUT.send_message(bend_reset_msg)
        # MOUT.send_message([CONTROL_CHANGE + ch, 0, 0])

Some times by playing around I get this user warning:

UserWarning: MidiOutAlsa::sendMessage: incomplete message!

What is this warning saying?

hint: See above for output from the failure.

This seems to be related to python/cpython#28968, where longintrepr.h was moved to cpython/longintrepr.h.

src/_rtmidi.cpp in the .tar.gz that Pip downloads seems to be generated with Cython, so presumably needs to be re-generated with a version of Cython that’s aware of this change.

For the record, I was able to successfully install from source (following the instructions from here) and otherwise everything seems to be working fine.

Installing collected packages: python-rtmidi
DEPRECATION: python-rtmidi is being installed using the legacy ‘setup.py install’ method, because it does not have a ‘pyproject.toml’ and the ‘wheel’ package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the ‘—use-pep517’ option. Discussion can be found at pypa/pip#8559

Is it possible to manage more than 16 channels in rtmidi? I have a synth (Fluidsynth) that supports upto 256 channels, but don’t know how to reach out to them from rtmidi. Any help is highly appreciated!

teymuri

for channel in range(16):

What exactly is the effect of going over channels in the inner for loop here? It would be the same to write the loop content just once, am I right?!

teymuri

Is there already an implemented way for doing microtonality in rtmidi?

Hey, I searched for a while and didn’t see the solution using python-rtmidi (maybe it’s because I’m bad at searching)

What I want to do is to read .midi file’s content and to get all of the events, notes or ticks, and then use midioutput to make something like autoplay.

Is there any possible way to do that using python-rtmidi?

JPfeP

Hello,

I would like to know if official support for Python 3.10 is on the way, and if binary wheels are planned as well ? Will it be possible then for you to provide a build for the new M1 arm architecture for Mac OS ?

Greetings,

I would be very glad If someone would help me understand the concept of channels. In the following (from examples directory):

note_on = [NOTE_ON, 60, 112]  # channel 1, middle C, velocity 112
note_off = [NOTE_OFF, 60, 0]

How could I send a note to different channels? I.e. why can’t I use channel numbers in the note_on list to sepcify the channel?

Question: do you anticipate any problems when trying to distribute this module with a blender addon.
If not: are you able to suggest any alternative strategies for installation with a view to building midi controller capability for the Blender environment (ie. should I build a separate stand-alone service to communicate between midi devices and blender addon).

PS. I got the following error when trying to install rtmidi using pip on Windows 10 with python 3.10.4
LINK : fatal error LNK1181: cannot open input file 'python34.lib' error: command 'C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.31.31103\bin\HostX86\x64\link.exe' failed with exit status 1181

I try to install the python-rtmidi but has error

i use python 3.11

Thanks for the software! I see that jack can be disabled. But since the readme speaks about compiling with Jack on MacOS, i was successful through this

brew install jack rtmidi
pip3 install python-rtmidi --global-option=build_ext --global-option="-L/opt/homebrew/lib/" --global-option=build_ext --global-option="-I/opt/homebrew/include/"

Otherwise i had trouble finding -ljack . There are may be more brew requirements

Hi,

I use python-rtmidi with several MIDI input ports at the same time.

So I create multiple rtmidi.MidiIn(), open a port, and set a different callback for each midiIn.

Is it the right way to do it?

because when I some messages simultaneously on several ports, I frequently get:
MidiInAlsa::alsaMidiHandler: unknown MIDI input error!

Using strace, I notices that reading from ALSA ports returns EAGAIN on these cases.

I tried to change the input queue size, and to put locks inside the callback function, but it does not help.

Do you know if rtMidi supports this?

Thanks

The first line of the documentation for each of the open_midiinput, open_midioutput, and open_midiport functions states:

Open MIDI port for input or output and return MidiIn/MidiOut instance.

(or an appropriate variation of the above). This is incorrect, or at least incorrect and misleading.

The Returns clause for open_midiport correctly states that it returns:

A two-element tuple of a new MidiIn or MidiOut instance and the name of the MIDI port which was opened.

This Returns clause is not present for open_midiinput or open_midioutput.

Someone trying to use the simpler open_midiinput or open_midioutput functions is going to be confused as to why this code:

midiout = open_midioutput(0)
midiout.send_message(msg)

gives them the following error:

AttributeError: ‘tuple’ object has no attribute ‘send_message’

The documentation for all three of the open_midi* functions should be updated to state that they return a tuple, not just the MidiIn/MidiOut instance.

I’m trying to install rtmidi_python on Windows for Python 3.10 without success.
It would probably help if the wheel was available out of the box.

Hi!

This is the first time I’ve tried using python-rtmidi. I tried to run the sequence example (sequencer.py), but the last three notes didn’t play. On a hunch, I added a pause in the ‘finally’ block and that took care of the problem. Is this expected behaviour or a bug?

I’m running under Python 3.8 and Windows 10.

try:
    seq.start()
    time.sleep(60. / seq.bpm * 4)
    seq.bpm = 150
    time.sleep(60. / seq.bpm * 6)
finally:
    time.sleep(5)    # added pause
    seq.stop()
    midiout.close_port()
    del midiout

Thanks.

Hey there,
I’m currently trying to communicate with a device via midi. I’m sending a message to poll for the device’s current configuration and it returns up to 30 bytes of data.

I can use the library to successfully send the device data but I’ve come across some problems trying to receive messages.

I’ve verified that the device is sending back data via the use of MIDI OX.

I’ve also verified that get_message() works with conventional midi devices by running the same code with an oxygen8, So this leads me to believe that get_message does not listen to sysEx commands

Here is the code that I have written so far in trying to communicate with the device
