[seq24-users] Problems with underruns with 6.3

[Paul D. <pau...@gm...>]

Hi there,

I've been getting large numbers of underruns with seq24. I'm not doing=20
anything too sophisticated, but I start to see underruns right away. The=20
biggest problem is that it crashes my Yamaha RS7000 horribly and nearly=20
gives me a heart attack every time.

Is there any diagnostic procedure I can do to try and find the cause? I'm=
=20
using kernel-2.6.12-2 (from DeMuDi), alsa 1.0.8-7, jackd-0.88.51-1 and=20
libgtkmm-2.2.12-1.1 (Debian versions). Everything running as root, very few=
=20
processes running my workstation.=20

I'm running Seq24 with jackd --realtime (48000 SR), zynaddsubfx -r 48000=20
(with three synths), qjackctl, and alsamixer.

Hardware wise I have a Pentium 4 1.6GHz, 256KB cache, 768MB RAM (200MB=20
free), and an M-Audio Audiophile 24/96.

I've recompiled the source on my system but see no difference between that=
=20
and the Debian package I was using.

I'm really enjoying seq24! Just hate it when I lose two hours work due to a=
=20
crash. Fortunately I'm just learning and the stuff I'm doing now are not=20
full songs.

I'd love to know (as an aside :o) ) how to use seq24 for automating other=
=20
midi controls like pitch, cutoff, etc. Is there some bezier magic I'm=20
missing?

Hope I can get everything working properly soon. I want to get good enough=
=20
to buy (and wear) the tee-shirt!! ;o)

Regards,
Paul
