Hey when I duplicate an instrument layer that has Omnisphere in it, it's not duplicating the plug-in state. So I'm having to copy the part "On" Omnisphere and then paste part back into the duplicated Plug-in. It used to copy the plugin state didn't it? I don't remember. Thought it did.
The only old beta I had was 1.1.2 and it worked there.
This is a bug in v1.3.2, which only affects Omnisphere 2. It's fixed in the latest beta, and we're hoping to get a v1.3.3 update out shortly.
In the meantime, you can manually copy/paste the state from the original layer to the new one, as a work-around.
