Problems with M Audio Uno MIDI Interface

Hi. I'm using the original versions of those packages included in 64Studio 2.1 release. I tested this on both the 64 bit and the 32 bit version. It only happens with the M Audio Uno USB MIDI interface; I have an M Audio Delta 1010LT card on my 64 bit machine and the MIDI runs without problems. The problem seems to affect mostly the MIDI output (I mean, output from Rosegarden to my keyboard). I recorded some MIDI tracks without problems using the Uno's MIDI In and running Qsynth with a GM soundfont for MIDI output. When I playback the tracks to the Qsynth, everything is perfect, but when I route the MIDI output to my keyboard through the M Audio Uno, the tracks's timing are sloppy and out of sync with each other.

Please give us more info on your software versions: Jackd Rosegarden Alsa Thanks,
