I'm usually using self-build kernel-rt in the past 2.6.x and today 3.x.
FWIW I've never been able to get an -rt patched kernel to work with
a dual core CPU without xruns and lockups. I've had better results
with standard kernels with pre-emption enabled. I don't use MIDI and I
haven't tried recent -rt patches though, so treat that observation
accordingly.
I think I'd be more likely to blame things like nVidia graphics drivers
and non-standard kernels before making a sweeping criticism of Linux
sequencing software, but maybe that's just me.
