Title says, required action:
Start recording at start of current empty item, if action ID is in item notes, wait until end of empty item, stop recording. This would allow creating a concept like Alk2, when used together with HeDa Regions&Markers from Items.lua . Or does this exist already?
The trick here is using empty items together with actions, action on at start of item, and action off at end of item, similarly as note on and note off.
PHP Code:
|<---------- item ----------->|
|start rec stop rec|
Coolness of this method is, you can copy, thus arrange such items.
