LV2 builds?

[dromer]

As you may know jatinchowdhury18 uses a JUCE fork to enable LV2 builds for their plugins.

Will you consider doing the same? this would make your plugins available to a wider audience.

That's probably a good idea, I'll add it to the to-do list. In the meantime if anyone wants to do their own LV2 build I'd recommend following this guide (also by jatinchowdhury18):
Building LV2 Plugins with JUCE and CMake

Btw I'm not sure how this host config for setting the samplerate will work, I don't think this is very typical for plugin hosts to set it like this.

[edit: oh wait, this is ELK configuration. I assume that the plugin works at other samplerates? (48k at least)]

[GuitarML]

@dromer It works, but the sound gets distorted. Since the ML models learn from audio at a certain samplerate (44.1kHz in this case), that's the samplerate that reproduces the most accurate sound. Ideally we would implement an internal samplerate converter, which is what NeuralDSP does in their plugins, reference

my LV2 port report

i assume something went wrong with git submodules
LV2 was CMakeLists.txt under FORMATS, but JUCE ignored that

what i did:

remove modules/DISTRHO-JUCE submodule, else it's not going to compile

- [submodule "modules/DISTRHO-JUCE"]
- 	path = modules/DISTRHO-JUCE
- 	url = https://github.com/Chowdhury-DSP/DISTRHO-JUCE.git

and from modules/CMakeLists.txt

- if(UNIX AND NOT APPLE)
-    add_subdirectory(DISTRHO-JUCE)
- else()
-    add_subdirectory(JUCE)
- endif()
+ add_subdirectory(JUCE)

replace JUCE distro submodule in .gitmodules with lv2 port

[submodule "modules/JUCE"]
	path = modules/JUCE
-       url = https://github.com/juce-framework/JUCE.git
+       url = https://github.com/lv2-porting-project/JUCE
+       branch = lv2

[jatinchowdhury18]

I was able to get LV2 builds working on this branch. Strange, it seems like I used the exact same approach as @mishushakov. Anyway, if you want to try it out:

$ git checkout lv2
$ git submodule sync
$ git submodule update --init --recursive
$ cmake -Bbuild
$ cmake --build NeuralPi_LV2 --parallel

[mishushakov]

success!

notice the CPU usage at the bottom (261%)
it stutters when i press "play" in reaper
maybe that's because i'm on a vm?

...and we should should probably mention in the docs, which dependencies are required to build, so you don't have to guess:

apt install cmake build-essential juce-tools

here's the .lv2 for anyone to try (built on latest Ubuntu, amd64): NeuralPi.lv2.zip

[GuitarML]

Great work all, thanks!

[mishushakov]

the usage was probably that high, because i didn't build in Release mode
