Support VST 3.7.8

[cbix]

On Linux with VST 3.7.8, these errors are thrown during build:

Are there plans to keep supporting later vst3sdk versions or is it simply recommended to stay on 3.7.6 (which still has some other issues on later gcc versions that have since been fixed).

Also it would be great to have release tags on the git repo so we can properly package this for Arch Linux :)

Hi @cbix it took a while but I am now looking into updating / maintaining all VST plugins.

Your request was originally for 3.7.8 but I have been working with the latest available version 3.7.9 build 61, assuming the minor version jump isn't an issue for you.

I have so far refactored the code to handle deprecations of the SDK and built on macOS. Could you verify whether branch 379 works for your Linux distribution ?

Could you verify whether branch 379 works for your Linux distribution ?

Build works here with VST 3.7.9, nice! Still having some issues running the full SDK build, but the necessary parts build successfully.

[igorski]

Hi @cbix thanks for the verification. But just to confirm : is it working or not ? You mention it builds, but are still having issues with the full SDK build ?

[cbix]

@igorski it works in Ardour and Reaper but isn't even found in Carla for some reason. By full SDK build I mean vst3sdk build fails after some time but after the objects needed by regrader are already built, so the regrader build succeeds.

Have you considered using JUCE rather than Steinberg's VST3 SDK for your plugins?

@tank-trax

Have you considered using JUCE rather than Steinberg's VST3 SDK for your plugins?

Honestly, not when initially building them as Steinbergs SDK is well documented (and heck, they invented the format, didn't they) ? But over the years I've come disappointed with cross platform stability of the SDK updates and breaking API changes on what are minor version bumps.

It's unlikely I will port Regrader to JUCE, but a future project might use it. Depending on ease of implementation I can consider a migration for the older plugins built using Steinbergs SDK.

[tank-trax]

I am on Linux and Linux is complicated. That being said I am using your plugins now with WINE and they work great, but needing to use the generic GUI as the knobs (although they work) do not display. DSP is great using this method.

Thanks

@tank-trax which distro are you on?

[tank-trax]

Debian 12, KDE Plasma, X11 or Wayland, using Pipewire
