VSTPlugin v0.6.1 - bug fix release

Spacechild1 · October 7, 2025, 12:14am

Hi everyone,

I have just released VSTPlugin v0.6.1 · Pure Data libraries / vstplugin · GitLab.

Please report any issues at Issues · Pure Data libraries / vstplugin · GitLab.

Have fun!

Cool! Will definitely upgrade soon.

Since finding ZL Equalizer and ZL Compressor (more or less FabFilter clones, but free + native Linux support without Wine), VSTPlugin has become a go-to rather than a “once in awhile.” You can roll your own dynamic EQ, but when it’s just 4 statements to load the plugin and open the window, it’s a big time saver not to have to.

Great stuff, I’m really fond of it.

ZL Equalizer and ZL Compressor look really neat, thanks for the heads-up!

Thanks for this fix.

I have realised sclang (3.15.0-dev [cf9d6f0]) returns the following error:

VSTPlugin 0.6.1
ERROR: objc[19447]: Class CocoaEditorWindow is implemented in both /Users/prko/Library/Application Support/SuperCollider/Extensions/VSTPlugin/plugins/VSTPlugin.scx (0x107cc4990) and /Users/prko/Library/Application Support/SuperCollider/Extensions/VSTPlugin/plugins/VSTPlugin_supernova.scx (0x107d70990). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

(When using SC3.15.0-dev [217e94c], I do not have this problem.)

The complete posts on the Post window from launching SC-IDE are on the following issue:

I guess this is because of Add stderr of sclang process to IDE post window (#6971) · supercollider/supercollider@000ee8e · GitHub.

Just ignore the error, or remove the VSTPlugin_supernova.scx plugin (if you don’t need it).
