Hi Mike :) the MIDI interface to external equipment at the moment is a no-name USB device, the no-name brand is called "swissonic", it's from Thomann, the biggest audio equipment dealer in Germany, but the jitter I reported was only tested with internal, virtual instruments. Rosegarden MIDI out by QJackCtl's ALSA tab (latest informations are, that this is only ALSA and not Jack) connected to Hydrogen, resp. QSynth to avoid any human touch function that comes with Hydrogen. The interface in this case is only the software interface, an ALSA output client connected to an ALSA input client. The 64 Studio users and Jack-Devel Lists are very helpful with this jitter trouble. At the moment it's up to me to test what will happen if I'll use RTC as timer for Rosegarden. I will do this tonight. There are also some other thoughts, but this seems to be the most promising one. I'll report later what will happen if Rosegarden uses RTC instead of auto. Cheers, Ralf
