Hi
I spend most of last night playing with LASH. I patched zyn, specimen
and seq24 and also use lash_panel + patchage.
However I have a problem. Often (almost precisely every other time)
closing a session will make some
programs (mostly zynaddsubfx) hang. They can't be killed with xkill or
killall. If zyn is the hanging program it will still appear in
qjackctl's midi connection. This will also take jack and lashd down,
and this is output to the terminal where lashd was started:
Project jesus_kristus removed
LASH event: LASH_Quit
Disconnected from Jack
Disconnected from Alsa
[JACK sync disabled]
Writing [/home/atte/.seq24rc]

So I figure it's a problem with lash in zynaddsubfx (if I only use
specimen it seems to work very reliable). My questions are:
1) Is there a way to really kill a hanging zynaddsubfx, when killall and
xkill won't work?
2) Does anyone have lash working reliable with seq24, sepcimen and
zynaddsubfx? Which lash patches did you apply to which version, and did
you have to do anything else? What distro? How do you start jack and
lash? Which kernel?
3) I tried with both lash patched I could find
(zyn-2.2.1-lash-jackmidi-060605.diff and zyn_lash-0.5.0pre0.diff) with
ZynAddSubFX-2.2.1.tar.bz2. Is there something newer/better/different I
should try?
4) Any ideas what could be wrong? Maybe it's something completely
Hello Atte,
I never try LASH yet, but something I can say is that Zynaddsubfx is not
enough reliable to do realtime work in combination with jack and other
softwares. Hydrogen is far better but not completely safe. Seq24,
Ecasound, Sooperlooper are rock solid.
This is strictly the result of my experience.

Philippe
