I'm running a stock fedora 20 distribition (latest updates > etc.) Hi David, I'm an old school MIDI user. The ALSA MIDI jitter test claims that my swissonic USB device should be ok, but I clearly notice the jitter. Beside my HDSP PCIe card I'm using two TerraTec PCI cards. Never ever use USB for MIDI real-time. You can use it to dump data, but not for playing music. USB MIDI devices are crap. If you need several IOs consider to get cheap PCI cards at Ebay. If you don't need several IOs, but you want that a few MIDI devices are in sync and you know how to use a soldering iron, consider to build a MIDI thru box. There are likely layouts available by the Internet. I build a MIDI thru box myself a long time before I used Linux, for my C64 and my Atari ST. It's wise to have separated outputs, a MIDI thru box only is useful in some cases. 2 Cents, Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
