As far as I can tell there’s no shortcut for this, and the closest thing requires you to write automation during playback. Plus, some plug-in parameters do not share the same name as their GUI presents, making searching for a parameter take far too long for an effective workflow. If anyone has a workaround please tell me, otherwise I feel this would be a really useful feature.
I totally agree.
but I have workaround that works nice for me:
I press play, then i press W button (its for automation wright mode on) then I tweak parameter, then I press W button again so wright mode turned off and then I press ctrl-z to undo changes on automation lane.
option to automatically show automation lane that being wright on you can find in prefs of automation panel. heres screenshot of how you can find it http://joxi.net/L219EwwCR8ldy2
