Thanks for the tool tip, Pablo. Unfortunately, the issue exists at a layer lower than qmidiroute can diagnose. qmidiroute is really nice to show all the MIDI messages, and I can see messages for every twist of knob or keypress on the O-25, but then they suddenly stop, along with any music. So it mus...

Hey Pablo, Thanks for that; I definitely wasn't in the audio group. Rebooted, re-logged in, but unfortunately, it doesn't fix the problem! Audio is otherwise fine. Been composing using the computer keyboard and Rosegarden and never had a problem playing anything. On the other hand, I do still have P...

Actually, could this be a Linux kernel thing? I'm using the Ubuntu low-latency kernel. Here's the uname -a output:

Linux hostname 3.2.0-23-lowlatency #31-Ubuntu SMP PREEMPT Wed Apr 11 02:24:03 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

That's probably the JACK watchdog kicking in because there were too many xruns (JACK couldn't send any audio anymore because the rest of the system responded too slowly). Like the keys stop working. The len...

Hi Pablo,

Happy to supply whatever information I can.

$ ulimit -r -l
real-time priority (-r) 0
max locked memory (kbytes, -l) 64

Not sure what this means or what I need. I've been invoking all programs from the xfce menu.

Does not seem to be the device. Tried it on the Mac with GarageBand for over an hour and never had a problem.

Please let me know if there's a better forum to discuss this issue.

Thanks,

Charles

Hi, I've been playing around with Rosegarden, Hydrogen, ZynAddSubFX, amSynth and decided to break down and get a midi keyboard/controller for more fun. But I'm having a lot of problems. I got it so I could control the knobs and dials in Rosegarden, etc from the keyboard. And I *am* able to get the O...
