  Hello

 Happy to find an open program to write my notes. Its just that I cant
 get the dam thing to play.

 I recompiled the kernel, so that the system time is 1000. I do have
 the Jack server running, and I installed the synth plugin.

 I have a Yamaha keyboard with medi in and out witch i connected to my
 computer with a usb cable.

 Sound is working fine elsewere in my ubunto so I expect alsa i working.

 If I open the MIDI device maneger it finds to play devices and to
 record devices.

 Pleace help me out. I tried all the options I coul find myself.

 A couple of questions. Is the snd-usb-audio module loaded? See lsmod for
 loaded modules. Also if you start Qjackctl, and look in  "Connections",
 and the "midi" tab you should see your keyboard sitting there waiting to
 be connected to rosegarden.

 Just a suggestion to checkout your keyboard creating sounds. Install
 ZynAddSubFX, and again look in Qjackctl's connections, midi tab. Connect
 your keyboard to ZynAddSubFX, and play a few notes. Any sounds??

 Hi Nigel
 The snd-usb-audio is loaded.

 usbcore     109144  6 snd_usb_audio,snd_usb_lib,usbhid,ehci_hcd,uhci_hcd

 ive been into Qjackctl and I've connected everything to everything.
 It does not seem to change anything.

 I installed the ZynAddSubFX and connected that one as well without result.
 When I open the ZynAddSubFX I can't make it play anything by it self.
 I figuer it's suppoused to make sounds when you click with the mouse
 on it's keyboard?  You should get sounds out of Zyn using it's inbuilt
keyboard, even if your 
Yamaha one has some problems. Have a good look at alsamixer's controls on the 
CLI (konsole/terminal). Controls like "master" "pcm"
"front", if you have 
them need to be unmuted and the sliders pushed up.

The fact that your sounds are working on Ubuntu is a good start. It's worse 
when you have no sounds at all.

 I hope this gives you a clue.
 I think its confusing.

 Kresten 

Which soundcard do you have? lspci will show you this. Just post the relevant 
bit for the soundcard.

You say also that you recompiled the kernel. Have you still got another kernel 
you can try, and see if the sounds work ok with it? Just a question, but 
sometimes something can be missed when configuring a new kernel. Saying that 
though, you say that sound is working on ubuntu.

Please make sure you do a "reply to mailing list" from your email client, or a 
"reply all" if you want to reply to me also, as there may be other folks that 
can help you with this problem.

All the best.

Nigel.

btw. Would you post the output of lsmod | grep snd
