    • librazik 5 probleme midi avec jack et controlleurs midi

    Envoyé par diigitae le Jeudi 14 mai 2026 17:58
    hello,
    j'ai un soucis je cherche a utiliser le midi(avec des surfaces de controles qui marche sur d'autres distro) pour controller sunvox et guitarix.
    quand jack n'est pas demarrer sunvox vois mes surface de controle(faderfox ec 4 et launchkey mini mk2 ou 3)
    une fois demarrer plus moyen de voir mes controleurs dans l'ongelts midi de sunvox,pour guitarrix le probleme est qu'il ne fonctionnent pas sans jack et de toutes façons il ne vois pas non plus mes preripheirques midi

    je joins ce que me dis le journal de cadence:

    Avant de lancer Jack, ce que tu vois, ce sont les ports ALSA MIDI.
    Et toi tu veux utiliser les ports Jack MIDI, ce n'est pas la même chose.
    C'est a2j qui fait le lien entre les 2 (alsa to jack), et tu as justement des erreurs a2j.

    Essaie de lancer

    a2j -e
    dans un terminal pour avoir plus d'infos sur ces erreurs.
