Greetings,
I'm testing the Linuxsampler plugin with Ardour3 SVN. The plugin loads
correctly, and when I launch the Fantasia GUI it identifies itself
correctly in the interface. I can load a MIDI file in A3 and watch it
play the keyboard on the LS plugin. Everything looks good, but there's
no sound. There's also no instance of Linuxsampler in QJackCtl.
When I run LS + Fantasia standalone I noticed that it doesn't
autoconnect to JACK. Perhaps this is the problem, but I can't find where
to configure LS to autoconnect.
Any suggestions ? This is a low-priority issue for me, but it'd be nice
to figure out what's happening.
Best,

Hello Dave!
I think LinuxSampler itself has no option to automatically connect. At least
I've never seen it in the protocol. this is a task for the frontends. So your
plugin should have an option to ayutomatically connect LS.
Did you see no LS at all:
ps -ax | grep linuxsampler
If not, perhaps the plugin just didn't start LS itself. Sorry, that's only
my little bit. :-)
Kindest regards
Julien

Hey Dave,
Check Preferences -> Backend to see if the 'launch backend if not started'
checkbox is selected. It should be.
If like Julian said that ps ax | grep linuxsampler does return true, you
need to create the audio and midi devices, in the device tab.
That's all I got.
Andrew.

Hi Andrew, hi Julien,
Thanks for the tips, but I'm no further. The ps report did not include
linuxsampler. :(
It's strange. I can see the voice allocation working along with the
keyboard display. But no sound.
I'll keep working at it.
Best,

Hi Dave!
Probably the voice allocation and the visual keyboard is just an add-on of
the plugin itself, so just visualisations. If your plugin doesn't start
LinuxSampler in the way andrew suggested, then perhaps youcould just start it
yourself on a terminal or an xterm and see what happens then. Although a
well-written plugin should tell you if it's backend is running and otherwise
report an error. But as you're the first to mention it here - at least I
believe so - it might be very young yet.
Kindly yours
Julien

in pure plugin sense, ardour is the host and it will care for all midi
and audio handling, internally. thus, you won't see any jack client nor
ports associated to the linuxsampler as a plugin, be that through
qjackctl or any other jack-aware patchbay application, afaics.
the linuxsampler plugin probably runs under host address space (ardour).
it won't appear as a separate process either ie. ps will show you
nothing about linuxsampler, but ardour.
all that it's being said theoretically, with the assumption that one of
the available instrument plugin specs is in practice. lv2, dssi or vst?

I don't know how the LS 'plugin' integrates in Ardour3,
but things don't have to be as you describe.
Even if something is loaded from an .so and thus
runs in the host's process, that does not imply
that it has to use the host's audio infrastucture,
or anything else provided by the host.
As an example, I have a collection of Jack apps
(Ambdec, Jconvolver, Jkmeter, and some others that
I've not (yet) released as standalone apps) that
are implemented as Python classes. You can use
them in Python scripts, or interactively as I
often do. Like all C/C++ extensions for Python
they are just an .so that gets loaded by an
'import' statement, and then you create as many
instances as you need.
So technically these are plugins. But each of them
is a separte Jack client, there is no common audio
infrastructure apart from Jack. Those that do have
a GUI are also a separate X11 client each.
Ciao,

yes, that's correct.
i was referring to plugins in the "pure" aka "traditional" sense,

ladspa, vst, dssi or lv2.
as a standalone jack client, linuxsampler should be available all the
time. you just talk to its lscp server via tcp to provide all the jack
client and port devices you want.
however, Dave has already mentioned that it's the lv2 plugin he's
tallking about. so i guess infrastructure is supplied by the lv2 host
here, ardour not jack.

Okay, thanks for the information, Rui. I'll post on the LS forum to see
if the devs there have advice. I'm just not sure whether the problem is
in Ardour or LS. I'd like to nail it down.
Btw, the plugin format is LV2.

that will be the way to do it. at present, we don't have plugin
instrument support complete. i am still debating whether this will
make it into 3.0 - it depends a lot on what remains to be done to make
it work (my guess is that its not much).
