You can add plug-ins, replace a plug-in with a different one, and remove plug-ins from a channel strip. You can also move, copy, and bypass plug-ins. If you’re unhappy with any of your plug-in adjustments, you can undo them.
Do one of the following:
Click the MIDI Effect slot, then choose a plug-in from the pop-up menu.

Place the pointer above or below an occupied MIDI Effect slot, click the green line that appears, then choose a plug-in from the pop-up menu.

Option-click the plug-in slot.
Click the center area of the plug-in slot to open the plug-in window, then click the Bypass button at the left side of the plug-in window header.

To bypass multiple plug-ins, click-hold a plug-in slot, then drag the pointer up or down.
All swiped plug-in slots switch to the same state.
