@RosDimitrov,
either use the mentioned approach from @pianopaul above:
Advantage: no scripting involved
Challenge: need to do changes to each rackspace
Another possibility is this:
Advantage: work needed only for rackspaces that involve global plugins
Challenge: a little one-time scripting involved
Or the Auto Bypass Scriptlet:
Advantage: automatically unbypasses plugins based on their use
Challenge: needs MIDI
