@ercanbrack I heard of it, but it requires MSVC which loses all my interest.

KXStudio July 2025 project update
https://kx.studio/News/?action=view&url=kxstudio-project-update-july-2025

It is basically:
- J2SC first release, which superseeds Cadence
- Carla 2.5.10 release
- WineASIO 1.3.10 release

@lunarloony the non-blue food eating people are becoming a minority :(

@dreamer tempting but j2sc is also fine. it rolls off the tongue, je-two-se-k 😂

If you have not noticed, I have silently abandoned the Cadence project. It was one of my first projects so code quality was/is quite poor.

I do like the JACK configuration tool from it quite a lot and want to keep it, so I have "forked" my own old project, removed a bunch of stuff and made "J2SC" for "JACK 2 Simple Configurator".

No release just yet, but did a bunch of work on it today and it is close.
Requires PyQt6 to run.

Tentative first 0.0.1 release next week.

@loki_bass I am not sure if they have to since it is a closed box, the Linux is practically working as firmware.

note they only need to release source to customers, if you didnt buy their product you have no cause to ask for source.

@uucidl wonderful, thanks a lot!

we received already 2 reports from users about this so they will be happy to know a fix might be coming

@uucidl ASIO, using a thesycon based driver as most companies do nowadays.

I submitted a technical report, number 3046776. There is a crash dump in there.

If it helps to get hands on with such a unit for testing I can provide that.

Thanks!

@loki_bass they are? how so?

Anybody knows someone working at Ableton?

Ableton Live crashes when picking Darkglass Anagram as USB interface because of its odd-number of IO (3 capture, 9 playback).
It expects USB IO to be stereo, but there is no such restriction in the spec afaik

> error: Windows Exception: EXCEPTION_ACCESS_VIOLATION
> info: Exception: Fatal Error: Unhandled exception

Cubase and Reaper work ok with it.

I summarized my Wayland + audio plugin UI adventures in https://github.com/lv2/lv2/issues/70#issuecomment-3067304097

I think in general it looks good, subsurfaces are a real blessing and I am glad to see it being well supported in compositors.

Well nevermind, fixed it in https://github.com/falkTX/wayland-audio-plugin-test/commit/ff9bdd884cfaeea95dd7402199a7741c39b7a727

(with some other little cleanup too)

basically I need to call "eglMakeCurrent(display, NULL, NULL, NULL);" to invalidate the GL context before deleting it.

everything works fine if this is the last thing the app does. crash happens if we create a new context after we delete one without "clearing" it first.

@dvzrv I think I solved the issue now, but doing some stress testing first...

seems we need to clear the GL context before destroying it. if not the next GL context creation fails badly.

Any wayland experienced developers can help out diagnose a crash in libwayland-client?

clone https://github.com/falkTX/wayland-audio-plugin-test
make && ./test-crash

(needs quite a few deps because its a test repo, should be obvious to any developer)

valgrind reports in the attached picture.

I suspect the load, unload and load again to be the issue.

@alf @dreamer yes, and related to this - I am happy that people are used DPF to create commercial plugins, it shows the viability for such things.

It is weird that they ignored LV2 though, since DPF focuses on that format first... 🤷
