  Toggle Current Track Automation Write/Read

Switch between Read automation and Write automation.

Read automation performs automation moves. Turning automation off is like muting the actions.’

Write automation writes over (replaces) any automation currently on the track. This is not a typical command.

When switching to Write automation Logic issues the warning

“Write” mode erases multiple parameters in one go without touching anything!
In most cases it is better to use “Latch” or “Touch”.

and waits for you to confirm what you are doing. The warning is only issued once (per session apparently.) The warning is issued if you create a key command to perform the operation.

Write: Erases existing automation on the track as the playhead passes over it. Records the new control movement or deletes the existing data if you do nothing.
