So I'll need a little help here. You should load the "uaudio" module. If it was not installed, then: cd /sys/modules/sound/uaudio make all install kldload uaudio or if that does not work: kldload snd_uaudio Replug your devices. > > I have two usb midi devices, a keyboard and a sound / effects module the > show up as: Sep 21 08:34:36 kg-quiet kernel: ugen0: <Evolution Electronics > Ltd.

Just don't forget to "chmod 777 /dev/umidi*" or "chown xxx:xxx /dev/umidi*" or something alike, so that midistudio can open those devices. --HPS
