If you have an audio interface active, then one of the PCM timers that Rosegarden should be offering in the preferences (whichever one corresponds to the ALSA interface in use) ought to perform more stably. I don't know about jitter, but it should be guaranteed not to lose sync with the audio at least. I think the only other solution is to use a kernel that prioritises timers in such a way as to make the system timer option work properly - this was the normal behaviour of an RT kernel ten years ago - but I'm not sure whether such a kernel is still readily available. Ideally Rosegarden would use JACK MIDI when JACK audio was in use, and that would avoid any of this.
