Logic: Gate trick using transformer object

In Logic create a software instrument track and add an instrument to it, such as a synth or piano.

Then go the the environment (Windows/Environment) and go to the mixer layer, then add a transformer object (New/Transformer) and check the icon box. Set the Status in the conditions to = Note and then in the operations menu set the status to Fix Control. Then in the Third operations setting set it to Fix 7 ( The image below is how all of your transformer settings should look)



Then cable the transformer to the software instrument channel (See the above image)

Then in the Arrange window ( Window/Arrange) set the transformer object to a track (image below)



Now if you add some notes to your Instrument track and then play the transformer track, the transformer track will open the gate.
