Configure MuseScore and Jack for playback to a MIDI keyboard
Ever wondered how to playback your MuseScore score on your keyboard? Now you can with Jack and MuseScore 0.9.6 for Windows. In this post, you will find the instructions how to configure Jack and MuseScore. I believe MuseScore is one of the first applications to support Jack on Windows so be aware this is still experimental.
Requirements
- MuseScore 0.9.6
- Jack 1.9.5 or higher for Windows
- A MIDI keyboard correctly set up
Configuration
Download and install MuseScore 0.9.6
Download Jack at http://www.grame.fr/~letz/jack-1.9.5.tgz
You can use 7zip (http://7zip.org) to open tgz files on windows.
Install with the binaries in jack-1.9.5\jack-1.9.5\bin\windows
run "Jack Control"
Choose "Setup..."
- server path :jackd -S -R -X winmme
- Driver : portaudio
Start jack server by clicking Start in "Jack Control"
Run MuseScore
In Edit -> Preferences ->I/O.
- Uncheck Portaudio and Use Internal Synthesizer
- Check Use Jack Midi output
Restart MuseScore
In Jack Control, click on "Connect"
In the "Connections" windows, click on the MIDI tab.
On the left side you should see Mscore1, this is MuseScore outputs.
On the right side you should see, your MIDI keyboard input, it's one of the playback.
Click Mscore1 and mscore-midi-1 on the right, and right click system_midi -> playback to link musescore with your keyboard

Now you can click on play in MuseScore or in Jack Control and you hear your piano playing
bonsoir
J'ai essayé et ça fonctione.Parcontre sur une partition comprenant une voix plus l'accompagnement au piano.Tout est joué au piano.Comment peut on modifier les voix ?
Merci
J'ai pas testé. Mais peut être avec Affichage->Mélangeur. Change l'instrument de la voix
La fonction mélangeur n'agit que sur le synthé interne.
Si l'on change les voix sur le synthé cela ne change rien non plus
Le soundfont fourni avec MuseScore ne contient que le piano. Il faut chercher un autre plus complet, et instruir le logiciel à l'utiliser. Et puis, tu pourras utiliser le mélangeur.

Fantastic! The only downside is that what JACK is running, it takes up all access to the MIDI input devices, so MuseScore can only be used with a computer keyboard input. Is there a way to configure JACK to only connect to MIDI playback devices like my sound card or "system_midi" while keeping the MIDI input devices available for MuseScore to use?
I think it's a not a Jack problem. It's a problem in MuseScore. When you select jack output in preferences then Portaudio is not initialized and then MuseScore does not "listen" the incoming midi.
