? side chain

That sounds good to me.
Like I say, you can sidechain gates in Logic and have them activate other tracks by varying the threshold.

For example, if you want a distorted guitar chord held over two bars, just slap a sidechained noise gate to the hi-hat and let the hi hat activate the audio track containing the guitar and you have a syncopated guitar track from a basic strummed guitar chord.

Cool, eh?
