Because updating all legacy plugins with wet/dry controls & stuff is probably quite the effort, why not release a little utility plugin in the meantime? Hosting Waves plugins within Waves plugins is already a common feature in all recent channel strips. Make it a single plugin, add Input/Output gain, Wet/Dry, MS Encode/Decode and bam. Call it Lil’ Gain and release it free for all Waves users.
Not a bad idea. Although, I’m not sure about the name!! Haha!!
Wait, forget everything I said. This shouldn’t be a separate plugin. This should be an update to the Waves toolbar
