Welcome to /dev/null

Le pocket Pod est un multi-effet plutôt sympathique qui peut être facilement piloté via des logiciels propriétaires. Ceux-ci s’émulent plutôt bien avec wine mais il reste le problème du pilote pour aller parler avec l’appareil en USB. Il existe bien un pilote mais celui-ci n’est plus maintenu et ne compile donc plus. En particulier le paquet Debian est plutôt cahotique. A force de ne pas profiter pleinenement de mon pocket pod du fait de la contrainte de redémarrer sous un autre OS, je me suis forcé à me fendre d’un petit patch qui sera peut être utile à d’autres. Il ne restera plus qu’à charger le pilote via un modprobe line6usb :

A mon tour de céder à la déco/peinture. Après disons une petite dizaine d’heure de ponçage, peinture, vernis, retour chez casto car les vis n’étaient pas à la bonne taille je peux enfin publier ma création!

Le meuble moche de départ :

Et maintenant avec un supplément de boobs!

Ça enlarge pas ta déco?

Guitar Pro est disponible depuis l’an dernier en version native Linux depuis qu’il a été réécrit en QT. Ce logiciel est, il faut le reconnaitre, à des années lumières de ce qui existe dans le monde libre, je pense notamment à TuxGuitar. Malgré tout, la seule distribution supportée par l’éditeur est la Ubuntu ce qui oblige à quelques contorsions pour que tout fonctionne sous Debian ou autre distribution. Je tiens à préciser que pour éviter de me battre, j’ai choisi de passer par pulseaudio comme sortie sonore sans utiliser timidity++ comme je le faisais avec tuxguitar.

Sans sudo, vous n’irez pas très loin car le logiciel part du postulat que vous l’avez. Il faut donc lancer un visudo et ajouter une ligne du type :

utilisateur ALL=(ALL:ALL) ALL


Installation :

# ar vx /chemin/vers/guitarpro6.deb
# tar -zxvf data.tar.gz -C /
# cp /usr/lib/libz.so.1 /opt/GuitarPro6/


Penser à lancer l’upgrade également ne fait vraiment pas de mal :

# cd /opt/GuitarPro6 && ./GPUpdater

Installer manuellement une banque sonore :
# cd /opt/GuitarPro6 && ./GPBankInstaller /media/Guitar\ Pro\ 6/soundbanks.gpbank /opt/GuitarPro6/Data/SoundBanks
