I notice you can edit the wet mix of the reverb effect directly from the panel. Although, while the song is playing, If you try to automate the wet mix of the reverb, the echo continues to play even when at 0. So, it must only relate to the start of the note, instead of its duration. I also tried editing the Active / Bypassed automation. Which worked in cancelling the reverb at a specific point, however, when you activate it again the reverb is lost, another downside to the Active / Bypass I found is you can only choose to edit with points, and not linear.
If anyone can help me with this, I would greatly appreciate it!
