Actually, ignore this topic, I'll be switching to Windows (at least for now). Seems like I won't be having these constant problems. But if you do find a fix, feel free to post it here for others, but...

The ATI hasn't worked in quite some time, that's why I got the Creative to replace it. I set the periods/buffer to 2, but it still crashes. I think I'll try restarting a few times to see if that...

output of "lspci | grep -i audio":

When I try to start up Jack under my sound card (usually hw:1) through qjackctl, it gives a lot of xruns and then freezes. I usually have to log out to stop Jack because "killall qjackctl" doesn't...

It took a good amount of tweaking, but I finally got it to work. Thanks to both of you!

Actually that sounds about right, and the keyboard does have an input for a sustain pedal but I don't have one. Do you know how I can set the CCs with software?

I tried amidi -l, but I'm not sure this is what I'm supposed to get, because it doesn't have the port number.

Actually after trying to restart with the keyboard attached, my system wouldn't restart and I had to install a new kernel, with which Jack doesn't work anymore. I'm still trying to figure out that...

I have an M-Audio KeyStudio 49 USB keyboard, which I'm trying to get set up with a software synth. I tried using MIDI in Jack/ZynAddSubFx and LMMS (by itself). Both times, I've been able to get the...

I looked around and found nothing on the support pages that related to my problem, so does anyone have any suggestions? Any support would be greatly appreciated.

So I dual booted Ubuntu 8.04 and Windows XP for a while before upgrading yesterday to 8.10. The graphics card was acting up a bit after the upgrade, so I installed the proprietary drivers and...

Thanks. Timidity is off now. It didn't solve my problem though.

Edit: Solved! StudioDave, you were thinking correctly when you mentioned the sample rate. There is some problem (probably a bug) in...

Here's a screenshot of my current Jack setup:

I noticed that taking Jack off of Soft Mode not only causes Jack to freeze up...

Believe me, I spent a while adjusting the knobs in Rosegarden and Qsynth and nothing comes close to working, so I don't believe that's the source of the reverberating buzzing. What else might effect...

Sample rate has always been 44100, which was default.

I actually just found out about a feature in Rosegarden to load SoundFont banks, and so I have all the sounds instead of just piano. But...

So I have Jack set up and everything, and Rosegarden works fine under Timidity. But I heard Qsynth/Fluidsynth works well with Jack, so I'm using that. Problem is, it doesn't seem to be loading the...

Okay, I'm going to ask around about soundfonts in the Multimedia Production forum.

Thanks for all your responses.

When I'm in Patchage/Jack connections, what specifically should be connected, and should anything be disconnected? I've been wondering, since I tend to just connect everything to everything so I...

I was wondering about that. I don't know how to tell Rosegarden what to use. I don't see it in the settings, just the Jack transport option.

Also I tried to load SoundFonts instead of just using...

Well when Rosegarden is running by itself with Timidity, it works fine, but when I open up Jack and use other stuff, it doesn't have any audio.

Wow, thanks for you input, Jack works now! And so do the other Jack programs, all except for Rosegarden. Everything works as normal on Rosegarden (including the Jack transport), but there is simply...

Another interesting thing, when I uncheck Enable Track Outputs everything works fine, but with no audio. When I check it then Hydrogen gives me error messages. Not sure what that's all about.

I've been having problems for many months, but now I'm determined to get Jack to work. I've been using Timidity for a synth in Rosegarden, but now I need other things (such as Ardour and Hydrogen)...

I simply need two (separate) percussion tracks in Rosegarden. Problem is, I'm not sure there even is a possible way to do this. For example, I have my first percussion track. It has a certain volume,...
