I think Studio One should include a feature like native "One Click Multi-Band" option by clicking we can use any plugin (which dont have native multi-band options) can be used as a multi-band plugin. If this can be done with a single or multi no of plugins (I don't care both are good for me). And it is up to you Presonus how you design it.
Provided by some Snapshots and a very rough design how it should look (I know my photoshop skills :P It is just for information :D)
And how I am using it right now...
Let me know what you guys think!
