The sound card I'm using, the M-Audio Delta 1010,
doesn't have midi, should I still follow these
instructions?

Both seem to be there, and I'm using the low-latency
kernel:
# rpm -q rtirq
rtirq-20050415-1.rhfc3.ccrma

# rpm -q rtload
rtload-0.0.2-1.rhfc3.ccrma

# uname -r
2.6.11-0.3.rdt.rhfc3.ccrma

I did try running jackd and jackstart both (since I
didn't know the difference and neither was working),
but I guess I'll just stick with jackd from now on.

Thanks.
