Hi everyone.
I'm trying to run Linuxsampler on Ubuntu 9.10.
I'm quite a newbie in the Linux World, but i did manage to make my emu 0404 work with ardour, hydrogen... I just need a sampler to complete my little home-studio !

The problem is that Linuxsampler does not seem to launch properly. Qsampler gives me something like this :

Code: Select all

10:12:25.527 Client connecting...
10:12:25.528 Server is starting...

10:12:28.743 New session: "Untitled1".
LinuxSampler initialization completed. :-)
LSCPServer: Client connection established on socket:4.
LSCPServer: Client connection established on socket:5.

When i want to add a channel, and create a midi or audio device, i've got a "Could not create device" message.

Someone to help me ?
Thanks.

PS : I'm french. "Connexion refusÃ©e" means "Denied connection"

Seems to be a permission problem. Try to run it as root.

It seems that it works better for lscp !
But the problem still remains : "could not create MIDI device" or "could not create AUDIO device"...
Here's the log I get :

take a look to your /etc/hosts file, be sure to have a line like :
127.0.0.1 localhost

(even better post that file content here)

AudioOutputDeviceAlsa: Can't find any card :
did you compile jack or linuxsampler yourself ?

are you trying to create an alsa audio device ?
if so, it will not work if jack is already running. Create a jack audio device
for midi, you can choose alsa or jack but for audio,
if jack is runing on the only availaible soundcard, create jack audio device, not an alsa one

Uuuuhm *cough* ... Have you checked your LinuxSampler version? I didn't actually see it last time. But according to your pasted console output, you are using Linuxsampler 0.3.3, thats a version from 2005 !!!

So please update everything and try again.
