With 1.07, we’re deprecating Input buses. If you migrate an existing project to 1.07, any effects and settings on its input buses will be moved to group buses automatically created for the purpose.
There’s a simple reason for this: Most input buses don’t actually do anything. We surveyed a number of users, and in any given project, the vast majority of input buses were left with their default settings… Meaning that they didn’t do anything that wasn’t going to happen anyway. Having input buses for every event, when most of those input buses were never actually used, seemed like a pointless waste of resources.
If you still want to have buses for specific events in your project, you can: Just create a group bus for the event, and route the event into it. (That’s actually what input buses did, under the hood.) This will give you exactly the same functionality, but only when you actually need it, instead of all the time.
