- -- Configure AT5 as a Mono/Stereo plugin in a mono Pro Tools track. The output of the track is now in stereo.
-- Send a signal to the track, verify that both channels of the track's stereo output are active.
-- Bypass the plugin.
-- You now have audio only in the left channel of the plugin.
AT4 didn't exhibit this behavior; input signal is routed to both output channels when bypassed. I'm pretty sure this is standard (and intended) behavior for all mono/stereo plugins.
Not a show stopper, and not something I do every day, but bypassing is useful sometimes.
