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:

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.
