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] JACK error: zombified - calling shutdown handler jack_mgr_shutdown_cb: JACK server shut us down; telling server to quit Cleaning up zombified - calling shutdown handler cannot read result for request type 7 from server (Connection reset by peer) cannot read result for request type 7 from server (Connection reset by peer) JACK error: cannot send request type 7 to server JACK error: cannot read result for request type 7 from server (Broken pipe) jack_mgr_destroy: could not deactivate jack client JACK error: cannot send request type 7 to server JACK error: cannot read result for request type 7 from server (Broken pipe) Finished 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
