A few years ago I made a MIDI and Audio patch that allows you to bypass all devices in the track it is on. (they are the same - but the MIDI one just allows you to position it further to the left):

bcBypassFX1.1.2.amxd

I have been asked if it can be adapted so you can put it on the Master Channel and bypass all objects in the entire Live Set at once. As I haven't looked at this for years, is there is an obvious solution I am not seeing at first glance?
