No GUI for clap plugin in Bitwig

[greatest-ape]

A report has come in of no GUI appearing in Bitwig when using the CLAP plugin.

I can confirm this, clap shows in Reaper, not in Bitwig

[TjShredder]

I can confirm this as well. VST shows the GUI...

[greatest-ape]

The latest release should now work on Windows, but unfortunately not yet on macOS.

[tank-trax]

still no GUI in Bitwig for the CLAP on my end v8.4 on Linux Mint 21.1

[greatest-ape]

Alright, annoying. For some reason Bitwig doesn’t seem to play nice with baseview / iced_baseview.

[TjShredder]

You should report it also to Bitwig, they want CLAP to be a selling point and might help you to sort it out...
Its all new and exciting...

[tank-trax]

good idea and I agree

Maybe related free-audio/clap#323

[greatest-ape]

Yeah, that looks related.

If any of you have the time, could you please try this build out and see if it works?

FYI https://nakst.gitlab.io/tutorial/clap-part-3.html shows .set_parent not just storing the host window pointer, but also setting it as the plugin window parent by calling [parentView addSubview:mainView].

Edit: I now realize the open_parented() call in show() is what effectively ends up doing the same thing as the above example, except here it happens in the show() call because open_parented() both creates and shows the plugin window. Hope my understanding is correct.

Your tmp build gives the CouldNotReadMetaDataException during scan (but clearly some versions did pass the scan before). This is with Sonoma 14.4. Maybe it's an OS issue?
Installed using

cd ~/Downloads
unzip OctaSine-tmp-2024-03-16-macOS.zip
sudo cp -r OctaSine/CLAP/OctaSine\ v0.9.clap /Library/Audio/Plug-Ins/CLAP
sudo xattr -d -r com.apple.quarantine /Library/Audio/Plug-Ins/CLAP/OctaSine\ v0.9.clap

But! Your work-2024-03-09 branch built here does show the GUI. 👍

[greatest-ape]

Yes, you’re right about open_parented, so it’s just a way to try to make it work with the baseview API.

Nice! Does CPU use drop again when the plugin window is closed/hidden? It was an issue previously that it did not, because the window wasn’t properly cleaned up.

I can build the latest VST2 but not the Clap as my rust is not recent enough using Debian 12

[josb]

Thanks @greatest-ape, for confirming my understanding around open_parented().

I'll look into the CPU behavior soon and will report back. Looking at recent commits, latest iced_baseview is supposed to have addressed this.

Ok! Are you using Debian-packaged Rust? My current rust version policy is latest stable and I will probably not change it. I was happy to be able to get off nightly Rust a while back.

Ok, thanks!

I’ve switched to a fork of iced_baseview since I don’t want to upgrade to a more recent iced version yet, since it causes various crashes, bugs and performance issues that I don’t want to spend time on ironing out.

can confirm too lol
