I'm running BFD2 for my drums on rock tracks and have made a kick sound in operator to go in time with the kicks. I was wondering if I could somehow side-chain the operator kick sound to trigger a hit whenever audio comes into the kick audio track of BFD2. There's probably a very simple answer to this, and all help or tips mentioned is greatly appreciated! It takes forever to write out midi to coincide with the kick by hand!

Thanks,
