Théoriquement ca fonctionne avec les outils KDE ?? Ce ne serait pas un conflit avec artsd de la version 3.4 si tu l’as mise ?

Audio hardware
Rosegarden requires and uses the ALSA sound drivers to drive your soundcard. The Rosegarden project itself has no control over whether a card is supported or not: it depends entirely on whether the card has ALSA support. To find out whether your hardware will work with ALSA, look it up in the ALSA Soundcard Matrix.
Of course, if you’re using an external MIDI device (sound module or keyboard) you’ll also need the appropriate leads and cables.
For help setting up your home studio for easy audio and MIDI recording, consult Bownie’s DIY Guide to Recording.
Software
Rosegarden runs on Linux, so you’ll certainly need that.
For its user interface Rosegarden uses the KDE 3 libraries, so you will need KDE 3.x with Qt 3. You don’t actually need to use the KDE desktop, you just need the library packages installed on your system.
Rosegarden requires the ALSA sound drivers for audio and MIDI support, and you will need the JACK audio server if you want to do audio sequencing, although it isn’t necessary for MIDI.
Please also consult the FAQ for more information.

j’ai désactivé artsd et j’utilise alsa mais rien…
Rosegarden c’est du MIDI non ?
Quand tu lis un fichier MIDI ça marche ?
Regardes aussi si tu as le
JACK audio server : c’est marqué ‘obligatoire pour le sequencing, mais pas pour le midi’…
