A user of my plugins has let me know that my plugins no longer work properly in Sound Forge 11 (they worked in Sound Forge 9). When rendering the plugins, they switch to the default plugin settings. Here's some information on the bug from a different manufacturer:
1) Parameter reset when rendering
For rendering, Soundforge does not use the Plugin instance that you can see. It opens the plugin a second time without showing it. Normally all parameters in that second instance should be set to the same values as in the visible one. It seems that this does not happen when the plugin does not make use of the standard VST default presets. We do not use these VST presets, as we have our own internal preset management.
I don't make use of the internal presets, either.
Quite frankly, this seems like a Sound Forge bug, but it seems like Sony has no inclination to fix the bug, even when told about it. So I figured I'd ask here and see if anyone has suggestions on how to work around this, in a way that won't crash stuff for hosts that don't have this "feature."
