Folks,
Now that I got some things running (jack, Zyn, Hydrogen and Ardour)
not int he best of ways, but still, I get fun from trying this and thus
doing little jams. I reckon that I have a lot more to learn and would
eventually like to use Studio64 (now using CCRMA) to take most benefit
from the machine.
So now that I do some jams using accoustic guitar and software-based
sounds, I start to wonder if there are any song (i.e. project) managers
out there that could, say, launch all apps with the proper settings
according to a song ?
Better yet. We have MIDI. This is quite a standard that everyone
seems to adhere to. We have Jack. Now, is there a standard means to IPC
between audio apps ? Such that a song manager could IPC (and
eventually launch apps that are not running) to the various apps used
for song, setting along the way the parameters for each app through
IPC ?
Such a song manager could, using this standardized IPC, get a dump of
relevant settings from all apps contributing to a song project and save
that to disk to be recalled at a later time. Project templates could
also be made.
So, are there any utilities like that out there ? Is it possible to
IPC to at least some of the audio apps out there ?
Cheers,
Al

its called LASH (Linux Audio Session Handler). its a work in progress.
not all apps support it. in fact not a lot do, but virtually all of them
should. my own apps included (ardour in particular).

LASH is a "session manager" that some (but not all) apps already
support. It is supposed to do what you need but I have not tested it
personally.

I've been thinking about this recently and have come to the conclusion
that the reason no one is adopting LASH is not because we don't want it
but because the documentation is damn confusing.
It's not that there is no info but that it is so verbose and not
straightforward enough for most programmers.
I would like to know if others have the same opinion.
It's not like DR is purposefully trying to make it difficult to
integrate. On the other hand Dave is not exactly reknown for taking on
the easy audio tasks or being interested in dumbing down his language on
the lists.

Well, thanks for the lead in. Prior to this thread I was completely in the
dark as to how to go about setting up a LASH session. More info about python
bindings would be great. I'll try to remember to keep some useful notes as I
explore further.

I recently tested lash and decided to use bash instead. I found it
impossible to get reliable results from lash, where bash scripts on the
other hand work well.
I agree that lash would be way better, but IMHO it's simply not (at all)
ready for actual use yet.

Ooh, you documented your problems in all detail, posted about
them and/or filed bug reports?

Something like that, yeah (except the bug report part, reason explained
below)...
I forgot to mention that it wasn't really a problem with lash itself,
but the quickly-done lash-implementation in some of the programs I used
(and want to use), most notably specimen and zynaddsubfx.
Reason for no bug report:
Both programs are not very actively maintained, and lash support from
the users point of view is a matter of finding the right patch and
applying it to the source. This means that there's not really *one*
person to talk to, since the people maintaining the software didn't
implement the lash support and the authors of patches doesn't maintain
the software.

Last I heared of Zyn, a complete rewrite was planned, so any bug report
is indead likely a waste of effort :)
But Eric Rzewnicki took over on Specimen, and there has been some
activity. He even asks for "any ideas you have concerning specimen's
future."

I've written the LASH patch for Zyn. I'd be happy to try to fix any bugs
you find if I can reproduce them.

Ok, here's a repost of what I wrote. Meanwhile I moved on a bit (changed
from ubuntu to debian on that new laptop), so I cannot reproduce it
right now, since my zyn is not patched. This was posted here on
2006-08-12, I got two replies none of which were really helpful in
solving my problem, which is why I let it go.
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
different...
