The most common reason for this (and something that I really must add to the FAQ) is that Rosegarden is using the wrong timing source for its MIDI event timer. This can happen if you're running JACK and you have JACK configured to output to a soundcard other than the first one (i.e. not hw:0). Rosegarden has no way to find out from JACK which device it should sync to, so by default it always uses hw:0 if JACK is running. If this is the problem, just choose a different timer in Rosegarden's configuration dialog (on the Sequencer -> Sync tab). Chris
