Hi again,
debian stock kernels are not rt. In order to work with lower latencies and
boost audio performance you need to patch the generic kernel.
A fix for midi should be in this rt patch
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.26.8-rt16.bz2(
but I am not sure) and higher. Otherwise you can download the patch here

Actually I am on 2.6.29-rt-vanilla, debian way compiled, on testing/squeeze
but I did it on lenny a couple of days after it was released.
When compiling from vanilla sources you must prevent compiler warnings to
stop building by checking "Kernel hacking" -> "Continue building
despite
compiler warnings" and then go with make-kpkg as usual on debian.
Where did you get "Debian Way" sources for 2.6.29?
The last kernel I made for rt patches that was workable was 2.6.23 which I got
prepatched from musix. Kernels I built for 2.6.25 and 2.6.26 had problems with
IDE DMA and were too dangerous to use (this was for a via chipset MB). I am
running an unpatched (none available) 2.6.28 without problems but have done no
audio on it. Things play OK.
