Still working on this, but initial tests are very promissing.
See http://i.imgur.com/QPiGoQV.jpg and http://i.imgur.com/z9XmZ2F.jpg and http://i.imgur.com/D3KS1rj.png :lol:

Can you spot it? :D

yes! :mrgreen:

Only the rack mode will work for an initial version, but that already gives us a lot I think.
DSSI in Ardour3 and simple GIG/SF2/SFZ management at least.

I did a test yesterday and was able to use carla within carla within carla, etc... 6 levels deep! :lol:

Oh, yeah. I've seen it in the developer forum. Too easy to spot since there are knobs in ZynReverb.

Perhaps LinuxDSP can port an interface for SR-2B that is small enough to fit in a Carla rack without having to open up an LV2 interface.

it's not about plugin skins. Javafant got the right idea.

This may be a silly question, but what is the purpose of running Carla as a lv2 plugin? If I'm using a host which supports plugins why add an extra layer (Carla) to load a plugin? Well, I could see you could add support for plugins not supported by the host, e.g. running a dssi plugin in Ardour via Carla. Can Carla host itself?

There are several reasons for this, you just mentioned one.

For me it's about having plugin-racks in a single slot (jack client). This makes me possible to have complex carla projects self-contained, and not using 3-6 carla instances instead.
When the internal patchbay is working we can extend this even further. Users will be able to make complex plugin modular setups and save/share as presets.

Yes! My record so far is 6-levels deep (Carla with a SFZ file within Carla within Carla within Carla within Carla within Carla) :lol:
It can go as deep as you want.

Hem... does that mean that windows vst plugins will work through Carla in LV2 hosts ?

in due time, yes. why not?

btw, the "carla-rack" lv2 plugin should now be usable if kxstudio users install "carla-plugins-lv2".
there's an issue with the ardour3 build regarding qt libs, I've reported the issue to Paul Davis.

(yo dog...)

restoring state doesn't seem to work after the 3rd carla.

Will this be limited to carla as lv2 or do you also plan to add carla as dssi, ladspa, …. This would e.g. Renoise enable to save the state of LV2 plugins.

it's complicated.

for DSSI:
- no time-pos (I can hack a jack client within the host to get transport info as done in dssi-vst, but it's not optimal. renoise has jack-transport disabled by default)
- no midi-out
- no host save (users would have to click save on carla's UI)

for VST:
- need an extra window (like a simple image+button) that will start/stop the real carla UI
- multiple plugins in 1 vst (aka vst shell) is not supported by most hosts (not sure if renoise does)

so an alternative to lv2 would probably have be VST, but it won't be perfect.
