[Rosegarden-user] Metronome silent on 20:USB midi - metronome plays on 129:Synth input port
I setup jack, qsynth and rosegarden according to the instructions in the Fedora Musician's Guide. In qjackctl, on the ALSA tab, rosegarden output is connected to 20:USB Midi input. However, in rosegarden, if I send midi output through 20 USB midi, I can only hear the midi keyboard. But if I send midi playback through 129 Synth input port, I can hear both the metronome and what I play on the midi keyboard. I would like to hear both through USB midi.

I gave up trying to keep track of these issues years ago. I notice you already have the 1000 Hz kernel timer according to that system check utility. It's odd that you get the warning in spite of this. I was thinking maybe I had the right timer resolution myself, and our warning was simply broken, but no, I ran that same utility and my setup is wrong in almost every possible way.

One thing I noticed is that midi seems much more precise and less 'jittery' if jack latency is low, epsecially with alsa-midi, but I think this is something different. I also wonder if/how alsa and jack midi relate to this kind of issue.

I have the same problem currently, and have been debating what to do about it. Several years ago, they changed the default timer resolution in the Linux kernel from 1000 Hz to 250 Hz. We implemented the warning back then to encourage people to recompile their kernels with this variable set back to the original 1000 Hz. There were several distros who shipped "studio" kernels that had this option set to our requirements, but these days that no longer appears to be the case. In the years that have passed since all of this changed, I've never seen one other Linux MIDI project express any concern about the kernel timer resolution change. Rosegarden seems to be alone in worrying about this. I have been thinking maybe it is time to just remove the warning and let it go.

At least with 3.0 kernel the system locks if you use hrtimer with a sequencer. A realtime kernel is something people used to boost the jack performance with slow CPUs. It's not needed for Rosegarden's functionality. Important für Rosegarden is a kernel with HZ1000 enabled, that's the scheduling frequency. Then Rosegarden's warning disappears. Check if it's enabled. If not, enable it and compile the kernel again. Regards Holger-- Don't let slow site performance ruin your business.

[Rosegarden-user] Warning maessage "resolution timer" with rt kernel and hrtimer mod.
Hi all! I am (french) musician discovering Rosegarden, that look very good! ;) Great soft. I'm also a contributor of the linuxmao.org team (Xzu Rukneg), I'm a free musician. I use multiple distro, I have no problems with TangoStudio(.tuxfamily.org). But I need to use a recent distro (for ffado), I've optimised a debian wheezy with Xfce-4 for that, with a *rt-kernel*: uname -a: Linux ruknegstudio 3.2.0-3-rt-amd64 #1 SMP PREEMPT RT Mon Jul 23 03:37:45 UTC 2012 x86_64 GNU/Linux And I use *rosegarden 1:12.04-1* (last debian wheezy version). *Config test* (from linuxmusician): delpixzu@ruknegstudio:~$ cd realtimeconfigquickscan ; perl ./realTimeConfigQuickScan.pl == GUI-enabled checks == Checking if you are root... no - good Checking filesystem 'noatime' parameter... - good cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: Aucun fichier ou dossier de ce type cat: /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor: Aucun fichier ou dossier de ce type cat: /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor: Aucun fichier ou dossier de ce type cat: /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor: Aucun fichier ou dossier de ce type Checking CPU Governors...
