Automation events are like audio or MIDI events, but instead audio or MIDI, they store automations.
Why they are so good:
1.You can have your original track automation which is just deactivated if an automation event is above (fast&easy testing)
2.You can move fast&easy automation data from track to track&song to song
3.You can save automation events in your browser and drag&drop them whereever you want!
4.You can shorten it, duplicate it, reverse it, stretch it and delete it WITHOUT ANY RANGE SELECTION BEFORE!
5.You can make fast&easy complex on/off automation if the common automation is off and the automation event(s) is/are "on"
6.You can arrange your song much more intuitve with automation events!
7.You still can use track automations if wanted!
(The color below/above the automation lines on the screenshot is another good feature for automations!)
