studio.kx.carla's Issues

X11 is not a requirement

The build rules specify --with-x11 but this is not needed, should be removed.

freeze when add/change plugin path

Carla freeze when I want to add or change plugin path.

Environment: Kubuntu 20.04

Steps to reproduce:

• click on "Configure Carla",
• go to "Plugin Paths" tab,
• select any plugin type ("VST2" for example),
• click on "Add..." or "Change..." button.

Actual result:

• the directory selection dialog appears but Carla is frozen it is not possible to do anything. I have to kill it.
• there is no error in console.

Expected result:

• I should be able to select a directory.

Python import error

decided to try the flatpak version, but it did not launch. Maybe I am missing a runtime, but then again it should install those.

$ flatpak run studio.kx.carla

Unified standalone and plugin versions

It has come to my attention in #11 that flatpaks tend to have standalone separated from plugin versions.
This does not make sense for carla or other plugins where 99% of the codebase is the same between those versions, as they are built from the same codebase (it is basically only the entry point that changes)

Seems non-sensical to split the 2, since both (standalone vs plugin) will work the same way and have access to the same things.
In Carla the same file browser panel is there for both, for example.

Only difference is audio going through a separate application in plugin version, while the standalone can access the audio devices directly.

See the discussion on #11 for more details.

Enable 32/64bit bridges

For running software that does not match the current architecture, would be great to build 32bit bridges on 64bit OSes, and vice-versa.
No idea about the setup needed for this under flatpak

Set SF2_PATH and SFZ_PATH if valid

Not sure if such paths exist within the freedesktop spec, but Carla supports them so we could define them.

If such paths are not defined in freedesktop, perhaps they should :)

Use of local vs system plugin path is inconsistent

Some plugin formats are allowed ~./lv2 like usage, some don't.
This does not make sense, either allow all of them or none.

DSSI missing from merge-dirs

Someone forgot about it.
Also, related to #2 the wrong lxvst property is being used, it should be either vst2 or simply vst.

Enable Windows bridges

Requires Wine and mingw, no idea how to set it up for flatpak yet..

Use vst instead of lxvst

Not sure why lxvst needs to be used or where it even comes from.
Carla has always used vst to refer to native things, feels very weird and awkward to treat it different on Linux. Should BSD be the same? Haiku, GNU etc? Plugins are loaded natively, and VST works fine on all platforms (not that official SDK supports that in written form, but we do not care or use that anyway).

We should get rid of the lx prefix that does nothing but bring confusion.

Remove jack2 as dependency

Carla includes its own jack headers in the source and will open libjack.so.0 on startup to dynamically use JACK as needed.
So shared-modules/linux-audio/jack2.json can be removed from the build config, it is never used/needed.
