Use Jack2 ex 1.9.8 with the alsarawmidi driver, unfortunately missing
for the Ubuntu Studio Precise package, but jack2 is easy to compile and
other distros, e.g. Arch include it. 

Example: jackd --sync -Xalsarawmidi -dalsa -r48000 -p256

"alsarawmidi" is the only way on my machine to get hard real-time, aka
zero jitter, at least in the past. At the moment, perhaps regarding to
new kernels or new video drivers, my Linux are broken regarding to audio
productions.
