Hello Alsa Team,

may I try to explain my/our problem as short as possible.

We have been truing to hack a kernel patch to get a MOTU Micro Lite (5x5 MIDI USB Interface) to run within a Debian "wheezy" with RT Kernel.

We did get the five channels appear in #qjackctl or #patchage. we tried to receive input from #vkeybd and get output to #gmidimonitor

while on the Hardware we connected: MOTU Midi In 1 <--> Motu Midi Out 1 MOTU Midi In 2 <--> Motu Midi Out 2 MOTU Midi In 3 <--> Motu Midi Out 3 MOTU Midi In 4 <--> Motu Midi Out 4 MOTU Midi In 5 <--> Motu Midi Out 5
