Can someone who has Logic 5.1 (not 5.0 or 5.01) on the Mac please test this? Insert a plugin on an Audio Track. Attach a monitor to the cable output of the Audio Object. Tweak a plugin control - is there any CC or F data output at the monitor? Cable a "Bang 2nd Fader" fader to the Audio Object, and click it - do you get output from the plugin (ie do you get the plugin control values, not just the values of the controls that are on the Audio Object)? Repeat for an Audio Instrument, inserting a plugin instrument. Does the instrument output control data and respond to a fader bang? Thanks John Pitcairn
