Error message: An item with the same key has already been added

Hello y’all.

So, I’m trying to add a Plugin Alliance VST3-plugin, namely the VH4 amp-sim, and this error message keeps appearing. I manage to load the VST2-version, and it plays fine. But the next day there doesn’t come any sound from the song saved with the particular plugin. Hm. Something wrong with particularly this plugin perhaps?

Thanks for reporting… I’ll check it out.

I’m seeing that “An item with the same key has already been added” message for a different plugin. The plugin is “Wall of Sound” by Two Notes Audio Engineering: Torpedo Wall of Sound - Two notes

Here’s the relevant section of my log file:

I can provide a complete log file if that will be helpful. Using Cantabile (x64) 3.0 build 3628, but I just downloaded 3640, did a full re-scan and same difference.

Try build 3641 (or later). From the release notes, pretty sure this item fixes that problem:

  • Fixed - better handling of VST3 plugins with duplicate parameter ids (eg: Personus Ampire)

That did it! It loaded up in the most recent experimental build, 3643! NOW THAT’S FAST SERVICE :wink:
