I’m pretty sure I can do this, but I can’t quite see how to do it in the manual section on automation.
I have a guitar on an audio track and I would like to vary the level of send to the reverb on an FX Channel Track during the song. How can I do this?
Write-enable your track and then drag the channel’s send slider as required. You can edit your moves in that channel’s automation lane (project window) afterwards for fine tuning (look for “send 1” in the pop-up menu in the automation lane).
Play around for a bit - you’ll get it.
