USB is by far the most convenient way to get Midi connectivity on a
modern Linux PC.

Now, it looks like USB recording interfaces are all we have, so we don't
have a choice.  That ain't good at all.

That may or may not be necessary on recent kernels.  I'm running a
regular Linus kernel with full pre-emption turned on, and I seldom get
an xrun.  I'd only go for an RT kernel if your system isn't behaving
without it.

works with regular ones..
