I sucessfully compiled and installed ll-plugins (latest svn), slv2, lv2dynparam, elven,
and other lv2-like goodies, intending to play with some lv2 synths, particularly azr2.
Everything builds. I'm on jackd 0.103, using alsaseq2jackmidi for bridging over.
Problem is: lv2_jack_host will not show the GUI for the synths. It doesn't report any
errors either. Just shows a text dump of the parameters, and starts the synth. I can
indeed play azr2 and euohpria, but the sustain is nearly infinite, and the levels are so
high that they clip explosively at note-on.
I tried sending CC's, based on reading the .ttl files, but they seemed to have no
effect-- not even (especially) controller #7.
elven seems like it might be pretty cool, but it refused to launch, no matter which synth
I used (even its example synth), complaining that it couldn't initialisze LASH:
lash_init: LASH_START_SERVER unset, not attempting to start server automatically
[H:M programs/elven/main.cpp:127] Could not initialise LASH!
Could not initialise LASH
Didn't know LASH was an absolute requirement in order for elven to work at all.
But the Leslie and tonewheels on azr2 sound pretty damn good. I recorded a little bit of
the drone the not-quite-working-yet lv2_jack_host produced:
http://www.restivo.org/blog/podpress_trac/web/103/0/azr2drone.ogg
If I'm doing something utterly boneheaded here, please let me know. Because I'd
really like to have that GUI going so I can start actually playing azr2.

lv2_jack_host does not support the GUI extension. The only host I'm
aware of that does that at the moment is Elven (which I don't really
recommend for production work, ever - it's permanently experimental).
Nedko Arnaudov's Zynjacku used to do GUIs, but it's also a bit unstable
and I think that that particular feature is broken right now.
Also, it's probably not very useful to load Euphoria in any host other
than Elven right now as it requires unfinished extensions that no other
hosts support (and thus they should not load it at all once they are
completely LV2 compliant).
I tried sending CC's, based on reading the .ttl
files, but they seemed to have no
effect-- not even (especially) controller #7.
The CC -> control port mapping is also an extension. I don't think any
hosts other than Elven support that either at the moment.
elven seems like it might be pretty cool, but it
refused to launch, no matter
which synth I used (even its example synth), complaining that it couldn't
initialisze LASH:
lash_init: LASH_START_SERVER unset, not attempting to start server automatically
[H:M programs/elven/main.cpp:127] Could not initialise LASH!
Could not initialise LASH
Didn't know LASH was an absolute requirement in order for elven to work at all.
It is, mostly because I'd be very mad at myself if it somehow started
without LASH and I wrote something and then couldn't save the session. A
recent version of lashd should start itself when needed, if not you need
to start it before you start Elven (or set LASH_START_SERVER=1 in your
environment). But, as I mentioned above, I really don't recommend Elven
for anything other than experimenting - it's what I use to implement and
try out new extensions, and it will frequently be broken.
But the Leslie and tonewheels on azr2 sound pretty
damn good. I recorded a
little bit of the drone the not-quite-working-yet lv2_jack_host produced:
http://www.restivo.org/blog/podpress_trac/web/103/0/azr2drone.ogg
Yes, the sound is pretty nice. All credit to "Rumpelrausch Täips" who
wrote the original VST version.
If I'm doing something utterly boneheaded here,
please let me know. Because
I'd really like to have that GUI going so I can start actually playing azr2.
I think your best bet right now is to get Elven going (or maybe Ingen if
you don't need the GUI and the presets - you can still control the
parameters without it from Ingen's generic interface). But while AZR-3
is mostly done, at least sound-wise, Elven is highly unstable and will
probably not be future-compatible. Also, Euphoria is very much
unfinished - what you hear today is not what you will hear tomorrow.
In a sense, this goes for all LV2 plugins and hosts. While the
specification is now relatively stable, it's still not completely
finalised and things may still break without notice.

I consider zynjacku itself stable but not yet feature complete. The
particular breakage is not in zynjacku itself but because of recent SLV2
changes that effectively disabled gtk2gui extension support because
zynjacku uses SLV2 to retrieve RDF data needed for displaying gtk2gui
GUIs. As soon as SLV2 reenables this functionality azr3 custom GUI will
show in zynjacku again. Until then zynjacku is able to show only
generated GUIs for AZR-3 and zynadd. In particular you can try changing
AZR-3 parameters through the generic GUI but dont expect too much from
it since AFAIK AZR-3 was never inteneded to be used with generic GUI.
I'd like to release lv2dynparam, zynjacku and zynadd as soon as there is
release tarball of SLV2 library.
As extreme case you may try to get SLV2 and zynjacku from svn revisions
prior recent SLV2 modifications.

I gather from yours and Lars' post that everything lv2-related is apparently an
extreme case right now.
I can wait a while longer.
I don't need the GUI anyway as long as the MIDI CC's work and are somewhat
configurable (i.e. through that .ttl file or some other means).
The ingen daemon runs on my system but the ingenuity GUI goes boom with:
"terminate called after throwing an instance of 'Glib::FileError'"
If I can figure out how to run AZR3 from inside a headless ingen, and how to set it up
using OSC or some means other than the ingenuity GUI, than that might get me where I want
to go.
I don't use LASH, so I probably won't get to use elven.

Hmm, OK, maybe I'll try again.
IIRC at one point when I was getting my machine set up, lashd was causing jackd to lock up
and/or watchdog out (jack.transport was doing the same) so I just stopped using them and

It'd be nice if elven had, as other programs (fluidsynth?) do, a --disable-lash flag
for ./configure.

It's not _that_ complicated. Just install the latest version, and

It works with elven. AZR-3 sounds fantastic! I will consider it the answer to the question
I asked a while ago: is there a free-as-in-freedom B3 out there?
It's not perfect: it's not really using tonewheels, just slightly warped sine
waves. At some point I'm sure someone will just grab samples of the some of the actual
tonewheels on a Hammond, make wavetables of them, and modify AZR-3 to use those. It's
GPL so that's possible.
Its Leslie sounds as good to me as the TAP Rotary Speaker LASDSPA plugin, and seems to
have less latency, too. It also has the speedup/slowdown code and even an adjustment for
belt tightness, which the TAP plugin lacks. Nice.
In a sense, this goes for all LV2 plugins and hosts.
While the
specification is now relatively stable, it's still not completely
finalised and things may still break without notice.
I built it using the recent slv2 release. There was one minor problem, which I think I
sent to Lars off-list, regarding a missing file, but after I came up with an awful hack to
get around that, it built and it works. Yay!
I will also try ingen, so as to get it going without a GUI, but elven was much easier to
build than ingen.
It remains to be seen how (if) any of this runs on a 64-bit machine, but I'll try that
