I got it compiled (pulled code today), but can't see any UI. Just the plugin playing default patch. Tried both QTractor and Ardour 3.2. Should I update them? It's really impressive, though! Maybe I'll just make a triumph with that default patch...

read the first post in more detail, you must make sure you have all the required dependencies for the UI (ie, NTK).
Oh, didn't notice that (without UI) there. Compiled again with all depedencies, and now it opens great!

I had the same problem, I was looking for NOs in the make feature output, until I realized that (half of an hour of googling later). Maybe you should specify that also in the main post.

Btw. It works and it's perfect, except for the usual problem with Zyn: parameter change on the fly doesn't work for notes which already playing, and if you'll add automation support, that thing would be great, even if I know that it depends on Zyn engine itself.
The old zynadd project seems to support that feature, but even if I was able to compile it, turns out that once it's loaded it doesn't work at all.
Do you have any plans about this?

I don't think this is an ideal setup when you want to mix/eq/compress/add effects to different channels using other plugins. From what I remember zyn's mixer is usable and you can also apply its internal plugins to different channels, so maybe it works as a standalone app but i wish it could either output to multiple audio channels or just forgo that capability altogether (in line with most other softsynths/plugins).

that's pending on some work on the current zynaddsubfx developer.
he's working on exposing all parameters, I'm waiting to see how that goes.
If that is not good enough, I'll just add the most basic params to be automable (like filter cut-off)
any news on this or are you planning to go in yourself?

Hello everybody, it's my first post here :)

First, I really want to thank falkTX for porting Zynaddsubfx to LV2!

Next, I have a little trouble with compile this plugin. Maybe someone could help me. Distro: Slackware 14 32-bit, gcc 4.8.2.

Apart from 1 issue (closing the UI crashing the host sometimes), everything seems to work great.

I'd love to have users with experience in building stuff to do some testing.
Volunteers?
I tested it today in qtractor (svn-version). Works great and seems to be stable except for a crash of the plugin and qtractor when opening the virtual keyboard.

Good job!

right now, if you're using the kxstudio repos (ubuntu or debian), you're much safer installing "carla-plugins-lv2" package.
I did some carla changes in latest git that are not fully complete yet, it might had broken something.
the packaged version uses and old but known to work code.
I tried to compile the stable version but it doesn't compile here. Maybe the lv2 base stuff is too new.

I can avoid the crash with vK when I delete the symlink "resources" in /usr/local/lib/lv2/carla-native.lv2 and copy the folder "resources" there. In this folder there are some unresolved symlinks as well but vK works.

Please tell us when Carla's git-tree is in a stable state. Thanks for your work.

Does this plugin allow to use midi controls to modify parameters in realtime? If not, do you plan to add it?

I currently have to use the windows vst with festige in order to do the former and I can't wait to see that working natively.

Thanks, and keep up the good work!

There's work by the current maintainer of zynaddsubfx to expose all parameters (might take a while), but I plan to expose basic parameters from zyn to hosts.
Right now you can use MIDI CC to automate things (see http://zynaddsubfx.sourceforge.net/doc_3.html), but it's not that great. Parameters will be better since hosts always have better support for them.
I can't wait to see that feature implemented. I really don't understand how can it be implemented in the windows VST, but not in the native linux standalone app.

Anyway, thanks for the answer. I'll stick to other midi controllable plugins for the time being (it'll save me the time of getting to understand zyn thoroughly, and then mapping it to my controller).

Collaboration with that particular fork have not exactly been fluid in the past and while their implementation does have this feature mostly working to my knowledge, there are a heck of a lot of issues that really need some much deeper work to get running smoothly. In the case of the mainline code, midi bindings is just a side effect of killing the horrid UI/DSP coupling that has been the source of xruns for ages.

At this point the midi stuff works fine, but the UI should have a plethora of Extremely Flammable signs attached to it. Fireproofing takes a lot more time than originally anticipated...

I cant imagine such a big parameter list for automation (just how many knobs are there in zyn??)

How about having a fixed number of possible parameters, say 10.
Then, by, say, middle clicking on a knob in zyn would pop you up with a short list of these and you could assign that knob to that parameter.

That would make it possible to control everything, but not being overwhelming at the same time.

What do you think?

About a million uniquely addressable parameters/widgets is the ballpark when you consider having multiple voices, multiple instances of each synth, multiple parts, etc.
I have code in place that could give an exact number, but I have yet to run it.
If you constrain the question a bit then I should be able to define the exact answer.

> How about having a fixed number of possible parameters, say 10.
Quick choose the 1e-6% best parameters :p
Of course this could be made into something much more reasonable when some context limits the choices, but such a mechanism needs to be defined.
Otherwise as long as a parameter is defined automation could be a relatively trivial extension on the system.
The UX is where the hard part comes in.
And for some controls, extra work might be needed to insure that things will interpolate in a relatively non-expensive manner.

EDIT: I guess I underestimated that as the total number of addresses is 6,347,092 at the moment (834 if you only count the 1st voice with the first kit, with the first harmonics, etc etc)

I don't think automation should be constrained to 10 parameters but it would be nice if there were some intelligent way to organize them (as opposed to how almost all DAWs currently handle automation, ie just a clusterf*** of params loosely organized/grouped by order in which they appear.

Agreed. I think this rests on the host. LV2 has an extension for port groups which organizes the parameters. I think the only host using that right now is jalv.

Hello, just wondering are the padsynth sounds somehow technically out-of-scope for being ported to lv2 plugin? (Related topic: http://linuxmusicians.com/viewtopic.php ... 010#p25987)

Or is it just lack of resources (time,money,motivation,etc.)?
